Swapping Bosch fuel pumps into a Regina car

15A · Sep 26, 2014

I've read of guys on here buying Regina cars and finding them converted to the dual LH fuel pumps. After a futile search, have found nothing on the details. The harness for the chassis pump is there - just tucked away. The bracket is the same, just missing the pump.

Was wondering what all was involved? Is there already relay'd power at the chassis harness (plug n' play)? AND.....did it also require a Bosch FPR as well?

TIA

I would find no physical reason for doing it. Economically, a clueless person might get "sender and fuel pump assembly it's $600-700 from Volvo." But, those with Pick-n-Pulls nearby might waste their time for such a conversion.

US $64.00 is current price on ebay for a regina pump.

Someone else noted, "My current DD/regina car just had the fuel pump died so I just threw in a walbro"

I'd venture to say GM's late 1980's in-tank fuel pumps would work too, and maybe cheaper.

Imho, only a bozo would install two pumps...

I have a customer who asked about it - whether he does it or not, I dont know or care.

And no one is asking your opinion, just an answer to the question which that thread didn't answer either.

My 1989 745 with Regina came from the factory with dual pumps - which is odd. It even has the LH2.4 powerstage mounted on the fender which is not connected! it is a true regina 745.. must be early production. Currently mine is running low on power, which I am trying to troubleshoot with no luck ...

Awesome - I was hoping someone here had one.

I've heard of 'some' having 2 pumps which makes me think its a plug and play setup. The only difference on the intank sender is the connectors, otherwise they're the same as well. My biggest curiosity is the FPR - is yours still the small Regina style or did they use the larger 2.4? With the same injectors as the 2.4, I can't see it being a problem to use the larger one......but dunno.

Forget those, use Gen III
1993-944 NA Regina with rebuilt B23F, AW71L, Bosch 0 280 155 746 Injectors

OEM 740 940 Bendix Deka fuel injectors # 1389563
These are high impedance injectors (14.2 ohms), and 18 lb/hour flow
The name SIEMENS is also associated with them.

Fuel Pressure Regulator...look up pressure specs

Regina cars

Fuel Pump: VOLVO 3507736

US $16.40 FREE Standard Shipping

So Regina and LH 2.4 (and 3.1) all have a max pressure spec of 43.5psi, which equals 3.0 Bar.

bosch pumps

It seems pre/main pumps these days are turbine type....As Bosch says,

Bosch brings the benefits of turbine fuel pumps to the aftermarket for late-model vehicles, as well as for many earlier applications with older technology fuel pumps. The superior design and industry-leading electromagnetic shielding of Bosch Turbine Pumps virtually eliminates fuel pulsation and noise, reduces hot-start problems and prevents on-board electronics interference.

Roller-cell pumps are still available, but are high $$$, and really have no use on stock vehicles these days.

Jeep, 1987-1990 used RENIX System on 4.0 LITER MULTI-POINT FUEL INJECTION, and Bosch 9580810019 pump was used, which might fit Volvo.

Regardless, there are number of pumps that could be made to fit. In a 740 Regina, that cheap $16.00 pump was installed last year, and it still works

Make sure your grounds are fit for duty.

From a Jeep Forum - This sensor ground circuit affects the CTS, TPS, IAT, MAP, ECU and diagnostic connector grounds. It?s very important and not something to overlook in diagnosing your Renix Jeep as it is common for the harnesses to have poor crimps causing poor grounds. If any or all of the sensors do not have a good ground, the signal the ECU receives from these sensors is inaccurate.

I'd love to get lh2.4 pumps in my regina 940. I'm a bozo in that way because I have handfuls of lh2.4 pumps but no spare regina pumps. I'm now on my 3rd Pro Parts replacement Regina pump (only one available if you don't spend huge money) in a year and a half. The car will start randomly cutting out while driving, and the pump eventually seizes.

So for me this is a worthwhile road to explore just for the availability of replacement parts and the (at least in my experience) issues with what's available for Regina.

Early regina use the large bosch FPR. Can use two pumps. Much prefer the quality of the bosch big main external pump to any of that GM ****.

Thats what I was hoping to hear. :-D

I think the guy is asking because he had heard something about 'some' having the 2 pumps, and hes never had a Regina car so is not crazy about having all his eggs in one basket/pump.

It seems that any issues I've ever had with Bosch pumps - one started making noise when the other began failing giving me ample warning to replace one/both. If the one and only pump failed, you're not going anywhere.

Thanks everyone!

What a PITA it is to drop that giant tank...

Best of my awareness, on Jeeps and 740/940s Volvos with Regina, you don't have to drop the tank.

Well now, chances are most all of these will work: check specs first
