Looking for a low buck solution for a fuel pump for a 2.0 F.I. car Options

[Mike Bellis]

I used the MSD pump on a V8 EFI system I built with good results.

On my last 914 I bought a pump from a BMW 320i. It was cheap and worked great 40psi out of the box.

Not a particularly good idea to try to regulate a 100 PSI pump down to 30 PSI. We call 'em fires waiting to happen ........ and they don't wait very long.

BS! (IMG:style_emoticons/default/laugh.gif) While I don't wrench on cars professionally, I do design hydraulic and pnuematic systems that safely drop 300+psi all day every day. Its perfectly safe to regulate pressue as long as your fuel lines and connections are rated for it. (IMG:style_emoticons/default/smile.gif)

I think the Cap'n point is trying to use a new pump with our 30+ your old fuel systems may not be up to the task. Specially if you move the pump up to the front and push through the plastic line.

I could see it as a viable option if you replaced all the lines with rated hose which I will be doing anyway. I have stainless tunnel lines. and I'm looking into that new lined F.I. hose for the alky fuel we have now. The only stock hose will be the injector elbos but those are reduced pressure.

Bosch has stated that the pumps are "not rebuildable". Mostly a problem in getting them to seal around the electrical connector from what I understand. Several companies (Python, Fuel Injection Corp, etc., )used to try to rebuild them. Haven't heard much about them lately.

Volvo, BMW, Mercedes Benz, VW, Ford, GM and who knows who else used the style of pump but in different configuration (single in, single out).

Best bet is single in single out (late 914). Never understood the magic of the 3 port. When I tested used pumps, they were capable of putting out in the neighborhood of 40 psi+.

Now, if you are running a flat six conversion with CIS .... double that pressure. (IMG:style_emoticons/default/blink.gif)

Ya, I used a Volvo Turbo pump and accumulator for the 928 CIS in the Alien. It requires way more pressure than your average F.I. car.

OK, I don't mean to be waking up an old thread but I found a cheap alternative for a 2 port EFI fuel pump, $44.95. The manufacturer is Hayg, found it at fuelpumps.com

Got a question. I've seen that there are pumps that can ccome very close to the factory psi but at about triple that of the flow rate , would the flow rate be compatable with the fuel regulator that comes with the stock system or would one need to go to a different regulator to keep the pressure / flow rate under control , if needed . Just asking because of going with a higher flow rate changes a spec in the system .
