Fuel Pump for Webers

[Amstaff]

What is the best pump for Webers and where do most people locate it?

I use a $30 12 volt inline 1 to 5 psi ebay low pressure one for 2 years now with no problems and I have it in the same location as the stock one which would be up front under the pan is. I have a PMO adjustable regulator and keep it at 3.5 PSI.

One like the Facet pump? The small square one or the cylinder type?

Round rotary pump. 3.5# max. 912fpmp is one I like. Carter makes a nice rotary. The square ones are crap and noisy too.

I've been using this one for the last 9 months with no issues. I have it mounted up front on the cross-member under the front of the fuel tank. I did quite a bit of research and decided on this one due to the configuration of the input and output both facing the same direction. Made for a very clean install given where I wanted to mount it.

I do not use a fuel pressure regulator, just a couple of in-line filters.

Here's a photo of my install...

I’ve had good luck on several cars with a low pressure Pierburg pump mounted by the steering rack. I’ve wired the pump through a switched relay so I can turn it off before shutting the engine off to try to minimize fuel percolation in the float bowls (let the engine idle a bit before shutting off to lower the fuel level in the flout bowls).

I prefer the Pierburg pumps over anything else unless using the PMO FPR with a Bosch CIS pump.

Avoid the little square Facet ones at all costs as they are really dreadful.

Oh my, I've been running the stock pump with an inline metal filter and pressure regulator for 20 years!!!!!!

Ditto on the Carter rotary pump with 3.5# pressure. No need for a regulator, works well, dependable, made in U.S.A, cheap, and can be found at most auto parts stores.

Is this the Carter pump ?
P/N P60504 , I did not find a spec for the pressure in the Carter site. Somewhere else they say it can deliver max 4 psi.

Looks like it. Same as the 912fpmp (pierburg) which has studs and nuts instead of push ons.

[blee]

Yup, that's the one I have on my car too. Come to think of it, John probably told me about them. I also added a pair of Mahle filters in the back, just before the Webers for good measure.



Gotta have pictures!
