For the benefit of 944Hybrids users there are two search functions available for you to use.

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Hi all,

What are people using for a fuel pump?  Is the turbo/S2 pump adequate?

Thanks!

Gord.

Stock pump is fine unless you are adding a bunch of power adders. You should keep a return line.

My car still has the factory 944 pump. It's keeping up fine at 389 whp, a/f ratio was good all the way to redline on the dyno. This with the factory Vette fuel filter / regulator and dead-head fuel rail.

Walbro 392, pumps the same as the bosch 044 for a fraction of the cost ($100).

Thanks, I already have an S2 pump, so I'll use that with the Corvette filter.

Corvette filter with regulator has a return line at the filter that goes to the tank, which allows a single feed to the engine. This works well with the stock 944 pumps.

Factory pump on a return system. Plenty of fuel at 6K+ RPM for 380whp

OK, thanks. Here's what I'm going to do:
-Use S2 pump in standard location.
- Add a Corvette regulating filter, to allow for return line operation. I assume this is to keep the pump happy?
- Locate the filter in the rear by the pump and use a single line forward.

Thanks for all the comments.

Gord.
