Walbro Fuel Pump Part Numbers / Sources

[TurboBrick940]

I have seen over and over people asking for part numbers and sources for the Walbro fuel pumps, well here it is. Now nobody has any excuse for not being able to find the info... Maybe Robin'll come over to the house sometime and we can do a VFAQ on the in-tank fuel pump install. :-D

The in-tank walbro pump I used was sourced from:

http://www.autoperformanceengineering.com/html/fuelpump.html

The walbro part number is GSS340

The P/N from the above site is FPG003 (a universal GM pump)- $108
http://store6.yimg.com/I/fuel-pumps_1740_1112605.jpg
This pump is a 255lph High Pressure pump.

:badboy: :badboy: :badboy: :badboy: :badboy:

Walbro also offers an inline pump which can be found from:

http://www.fuel-pumps.net/inline.html
http://store6.yimg.com/I/fuel-pumps_1740_76944.jpg
This is also a 255lph HP pump. The price is $140. This site also offers the Walbro intank, but they are considerably more expensive than the APE site.

thank u very much.

now it adds to list..........

[the poi]

hmmm. I like it, i approve. Any special notes needed when installing it, or does it slip into the clip ring pretty easy?

I just got mine like 5 mins ago. And dont know how to install it. Duh!

[TurboBrick940]

The in-tank pump was as close to a drop in as you could expect. It is a touch longer than the factory unit, but has caused me no issues.

[secondtwig]

www.extremepsi.com sells them......they're "for DSMs", but its the same thing, and fit perfectly on my 740. $95 I believe....

edit:// and too much money in my pocket, ordered myself one. borwn tops and megasquirt on there way...

[TurboBrick940]

Yes, comes with a wiring harness, strainer, etc. etc. I didn't need a single extra part save for 2 crimp connectors to splice the pump into the factory wiring.

[Hank Scorpio]

Actually mine had the connectors, you just need a crimping tool.

On a 240, because its a hair longer than stock, mine was jambed up against the bottom of the tank and made the pump quite loud. All I did was trim the metal tube (that it attaches to) up some, about 1/4" of an inch.

Mines been quite ever since.

I think I payed about 105 through Jegs, as a "Grantelli universal 255lph". A bit more expensive, but I already had a big order with them, so I just added it to the list.

saaay eric, while you're posting part numbers, how bout the number for your mother?

[secondtwig]

I hear she gets around............PM me for the # :rofl: :rofl: :rofl: :rofl:

She said "Have you SEEN Kenny?" :eek:

I hear she gets around............PM me for the # :rofl: :rofl: :rofl: :rofl:

Yea Reid she pawned your turbine housing for spare cash, looks like you'll get a stock one instead. :whip:

[linuxman51]

hatefull little bugger, isnt he? what she really meant by have you seen KENNY tho is have you seen his HUUUUUUUUUGEEEEEE









feet? :rofl: :rofl: :rofl:

[joel142]

I posted a more indepth, how-to over at the brickboard in the 140 forum so you can check that out if you can't figure out how to attach hose to hose fittings.

At any rate the upshot is that the inline pump fits in the existing spot in a 142 and works great just gravity/siphon fed (there is no intank pump for those of the 2/740 generation).

So far, it's done everything a pump should: it's silent, it comes up to pressure really quick and it'll supply more than enough flow for the B20E or my planned for B230FTi swap :twisted: (don't tell the brickboard, I don't want the thought police at my door).

Regina cars own you!!!!!!!! 8-)

1 fuel pump baby!! :woowoo:

[grizlyadams]

Any ideas for us UK lot, dont like the idea of ordering from the US, something that may or aynot fit my 1996 940.

Griz

[linuxman51]

how bad is shipping on something like that? Its not big and doesnt weigh that much. I've heard tell of kjet pumps being used, and I'm sure there are other hi flow fuel pumps (what do the guys with the cossies run?). They're pretty much a shoe-in to work, basically a fuel pump is a fuel pump is a fuel pump (with a few exceptions)..

[TurboBrick940]

...a fuel pump is a fuel pump is a fuel pump (with a few exceptions)..

Is that like when a fuel pump isn't a fuel pump? :-P

Good point, so you should be able to track down WELBRO in the UK or EU for that matter.

If you can get the part # for your factroy pumps, or pump, and post them here so they can be compared with the pumps used here that may help too.

The WELBRO conversion has been great for me, even though the 255lph high pressure pump over rides the factory fuel pressure regulator off idle by 10 more psi.

[TurboBrick940]

WELBRO will be tough to find, look for WALBRO.

I may just be a little retarded when it comes to fuel pumps, but....

Will the intake pump work in a volvo with K-Jet? And will I then be able to remove the stock main pump along with the prepump?

Thanks,
-JT

[MikeHardy]

bad news for us UK fellows, the HP walbro intank pump as listed in demontweeks is £150Inc VAT. so maybe cheaper the get one from the states as there $108 in the link above, which is £64 before shipping and vat.

From what I've researched......
K jet pumps together flow 120-140 L/h @ 5bar
LH jet pumps together flow 120 L/h @ 3bar

What this means to you is that a k-jet system needs a higher pressure than LH does in order to operate properly. The first chart within the link at the top of this page is where you want to look. 5bar equals about 73.5psi. I'd get a "high pressure" GM Universal if I were you, should do you just dandy.

[poulson01]

Do you use the pre pump wiring or extend the main pump harness back to the trunk?

[stylngle2003]

Mike brings up a very good (albeit quite old) point.

Do you splice the Walbro connectors in with the prepump (ie. in tank pump) wires, or run the main pump wires back to the tank when doing this install. The reason i'm curious is because I'll be doing this swap soon as my prepump has died on me, and I'll also be replacing the main (undercar) pump with either a section of fuel hose or another fuel filter.

Help a brotha out :please:

[grebnut]

hey ya'alls... thread resurrection time!

i am getting ready to set up the slovo with a walbro and am wondering if the 340, 341, and 342 are all the same? because they are different prices in most places. is that just so the retailer can make it SEEM like they are different? or will they all work? thanks guys... later,

ben

[stylngle2003]

i just recieved a GSS342 pump with install kit from Boostfed.net, and im very happy with its looks, as i havent installed it yet. ill admit it was confusing picking the right one, but i think if you get on the phone with someone and tell them you need the 342 which is a universal gm fit pump with install kit that is 255lph and high pressure you will get the right one

good luck

[The Aspirator]

You want the GM universal pump. I got mine from here:
http://www.autoperformanceengineering.com/html/fpapps.html
The very first one on the page, though I got the high pressure 255 ltr/hr kit for $108. Been running it for like 10 months now with NO problems at all.

I used the existing in-tank pump wiring for the walbro, and just left the main pump wiring hanging there (cause I removed the main pump).
http://www.vipinfoservices.com/john/images/walbro04.jpg

Here's a picture of the walbro next to my stock in-tank pump. In the end you want the sock to come within like 1cm of the bottom of the tank, but NOT resting on the bottom or else you could reduce flow potential and possibly create a lot of loud sucking noises. Do accomplish this I had to cut the metal pipe on the sender assembly back like 2".

For the wiring, in my picture anyways... the black wire on the sender is power and the green wire grounds to the sender assembly. So splice the red wire from the walbro into the black wire, then ground the Walbro's black wire to the sender body.

Here's how I replaced the main pump. Make SURE to use high pressure fuel safe hose. Yeah, it's stupid expensive, like $5.00/ft. Regular fuel hose is only meant for like 5psi in carb applications, we need 50+psi capable hose.

[stylngle2003]

thats a great set of pics John, thanks!

i need to get after Lloyd so i can look under his car and see if he has any pics from his 700 series install, but he's been busy

[grebnut]

nice guys... thanks for the help! ill have to do this sometime soon then. :) fuel is good...

a complete install guide on this would be great :D:D:D

And the pump we need is froma mustang again ? I ebayed the walbro part # and this came up:

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33555&item=7943092302&rd=1&ssPageName=WDVW

[Kirby]

dude it's easy. it's no different then changing the stock in tank pump really. just read your haynes manual.

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33555&item=7943092302&rd=1&ssPageName=WDVWNo it's NOT the mustang one that you want. It's the GM universal. Just buy it from the link I posted above, it's only $83-$108 depending on which one you want. Then you KNOW you'll get the right one, rather than some e-bay guy possibly posting the wrong information.

And with a Haynes manual, the info I posted above should be plenty enough to walk you through it :lol: .

[940T_Drifter]

Alrighty then :-D

Edit: Why all the confusion then ? Why is there so many part numbers flying around ??? :???:

I agree a simple table with the different Volvo models (IE) 8X 240 turbo- 8X 700T- 9X 900T and what pumps and part numbers would be GREAT...

Okay is this correct
240 turbo cars pump is ???

700-900 Turbo cars part number from APE SITE (http://www.autoperformanceengineering.com/)
FPG003 - $108
a.k.a. GCA758

[The Wizard]

Is any of my info correct??

[stylngle2003]

JUST found this link, hope aaron doesn't mind my using it because it is VERY informative. thanks so much Aaron!

http://www.aaronreedbaker.com/walbro.html

got some pics, lots of instructions, great site all in all...now there's no excuse for not doing this mod, so do it!

[940T_Drifter]

Awesome, I've been waiting for a reply to this thread for a while now. Thanks alot for that link :)

[r.friborg]

Hello

The saab 9000 Turbo, uses the same pump in the tank as Volvo uses under the car.
It is posibble to fit that in the tank whit some mods.

Mvh Robert

[940T_Drifter]

Yeah but the SAAB pump must be expensive no ? The walbro is relitavely cheap & powerfull.

[r.friborg]

You can buy a saab pump at the junk yard.
At least in Sweden

[940T_Drifter]

Well, I for one after investing a few thousand dollars in my motor will not be putting in a used fuel pump...

Just ordered mine and a supra one for my friend, better be right :p

[The Aspirator]

When you crack open your 700/900 series gas tank, I wouldn't be suprised if the pickup tubes and sender assembly look different than my picture... Dunno, I've never been inside anything other than my 240, just don't blame me if yours looks different! :) Though I'm sure the same pump will work just fine.

Can't be that different, I`m sure it will be fine lol

[ICE RCKT]

I just wanted to share that I've been running a GSS242, 190lph low pressure in-tank pump for 5000Km without issue. Main pump was deleted as per instructions above. I'm getting ~31mpg (9.3L/100Km) highway mileage on an otherwise stock 745T.

Thanks again to Matt/Dale et. al. out in Ab for the suggestion, it obviously works. And you never even hear it :).
