Fuel pump psi
Posted by: loots ()
Date: February 23, 2018 08:05AM

I am putting an electric fuel pump in the car. Mounting it under the car near the fuel tank. The one I bought is an Edelbrock 4-7psi from my local O'Reilly's. I liked the size. Its quite a bit smaller than some of the others I've seen guys using. Is 4-7psi gonna be to high or will I be okay? I've done some searching and see 4-6, is tje one psi gonna cause a flooding issue? Thanks for your input.

MAY be OK we usually use 2-5 psi. If too high just get a regulator.

I stay away from the plastic body fuel pumps like the edelbrock and mr gasket type, the facet pumps have done me right for years and think the ones I use are 2-4 psi, the airtex seems to be decent as well.

Agree with davem. NO PLASTIC

Typically the fuel pump pressure range equates to lowest pressure at highest flow rating and highest pressure at lowest flow rating. A Corvair only needs a low fuel flow so with MOST pumps you use the HIGHSEST psi to determine what the pump will operate at even at wide open throttle.

So the 4-7PSI pump will most likely supply 7PSI in your Corvair and that is excessive. Corvair spec. is 4-5PSI.

It's been awhile since I looked up the numbers, but at one thime the Facet #40105 was rated at 3-4.5PSI. The Airtex E8016S was rated at 2.5-4.5PSI. Both have a good reputation.

I looked on the O'Reilly web site to see what you bought. They show a #17301, #17303 and a 17302 Diesel pump. Edelbrock shows the 17303 as 2-3.5 psi @ 30GPH.

You can get the knock offs like this for less than half the price. I did that, but they were very loud, as I could hear 50' from the car, with not the best hearing at the age of 72. The cheapie did function fine, except for the noise. I then got this one and it is much quieter.

Yes I compared the AirTex and Carter pumps (looks just like the Airtex). The Carter pump was much louder vs. the AirTex

If it is too high, it will push past the floats.

I put a locally bought electric on my Dauphine, and after playing with the carbs and jets, I measured the pressure. It went up and down between 3 and 6 psi, with the engine stalling at 3. Switched it out for an airtex and it runs fine.

The one I bought for my Mini was supposed to be 15 psi, and it pushed out 50 psi. I had to put a regulator on it.

I got the Airtex from Amazon. Reasonable price, correct pressure and great delivery
