The BMW I stripped recently was full of mounts that were like a grommet with a steel tube in the middle. The steel tube was bolted down hard, and the grommet held the sheet steel item between it's...

Soft mount doesn't have to be non-captive.

Question: does that "surge tank" perform correctly on its side?

Some people call surge tanks "swirl pots" which is fitting as it gives the fuel...

Laminar vs turbulent impacts all fluid flow. You have laminar meaning in layers, outer moving slowly or stuck to the walls, and inner rushing through the middle with a sheer of sorts in between. When...

1/4 line is a restriction to a flow of 400hp of fuel, for sure. Will you get a decent lot of fuel through it? Sure, but the pump will be working a lot harder to do so, drawing more current, and...

No way would I run anything under 5/16 on the feed to any turbo engine worth any respect. Suits a crappy walbro, though :-p

Also, your return line should ideally match your post-pump feed line...

Carter black fits the bill. 397 lph free flow which is more or less what it's doing from my main tank to my surge tank and back. The 044 is only about 300 at low pressure, through to 200lph at high...

Fair enough re noise, fuel pumps are pretty loud if the car is a daily/street car. Even with the stock Volvo jello mounting you can still hear them way behind you.

That surge tank... hmmm, I...

A lift pump doesn't have to be inside the tank, nor does the high pressure pump need to be inside the surge tank.

The lift pump only has to supply the average fuel requirements of your use unless...

I would have thought you could buy a large needle-less syringe from a "drug store" locally pretty easily? No?



Good. I doubt it unless your tank was dirty or your pumped gas is, or you're...

Wait, just checked out the fuel pump install post, you have a filter before the pump! You can't do that. At least, not with a small one like that. EFI pumps are NOT designed to pull vacuum, and that...

You can test this at idle with a syringe and the...
