I am in the midst of doing a fuel pump relocation and wanted to know if I could use the smaller cylindrical fuel pumps to replace my 3 hose L jetronic pump. I have a 1974 1.8 liter.
Thanks in advance for any input.

Thats what Porsche did for the 75-76 cars when they stuck it upfront.
Use the inline pump and the inline filter with the larger feed hole.

The single-in/single-out VW pump will work fine, but it's the same size as the 3-line one. Porsche went to that pump for the 75-76 cars. If you're thinking of one of the smaller aftermarket pumps, probably not. You need to match up the pressure/flow with what you have. The Cap'n

What is the GPM and PSI rating of my oem pump?
What are the GPM and PSI requirements of my 1974 L Jetronic system for my 1.8 liter?
Is it that easy to find out GPM and PSI ratings of after market pumps? or other year 914's?
thanks

on my 914, I have a fuel pump from a 97 Ford Ranger, being fed from a line with a 914 stock fuel filter, then going way back and then going to a 300ZX fuel filter...
whole setup cost 100 or so dollars...been working solid for a dialy three months.
As dependable as a.....a.....honduh

What fuel delivery system are you running?
Carbs?
L jet?
D jet?

I'm using L-jet, but I went ahead and mounted everything up front (except for fuel filter #2) so I could get rid of the vapor lock issues....or at least that was the excuse I was using...shoudl work *EXACTLY* the same with D-jet, and if you purchased a regulator that would cut the pressure down to 3-4 psi from the FI pump, you could run carbs.

So you think that the D jet fuel pump would work fine mounted up front w/ the L jet EFI system?
I like that pump better. It seems as though it would be easier to service it than the 3 hose oem L jet pump.
thanks

The fuel pump from a fuel injected VW Type 3 should work. D-jet system w/three ports on the pump.
Nothing magical or extra difficult with a three port pump

I guess that you hit it on the head! about the 3 port "magic"
Cylinder pumps seem to be the way now.
what's up w/ 3 ports!
anyone know the psi and gpm of the old 3 port pumps?

Dropping the pressure from an FI pump down to 3-4 PSI is a well known way to prep for a fire. Seen several carbecues done that way . The Cap'n

As previous replies have stated, the later D jet cars used that pump, as did the L jet cars through the VW Vanagons. The Cap'n

I agree it would be stupid to do that, but it is possible to do.
