Delphi MF0001 Mechanical Fuel Pump

Q: how much fuel pump pressure?

The answer of 9 psi is terribly incorrect. This is a factory pump designed to put out 5 psi so says the spec sheet for this pump. If it actually put out 9 psi, it would likely lift the needles off the seats and flood the engine since almost all stock to mild factory and aftermarket carburetors that would require this type of stock GPH flow are designed for a maximum of 6.5 psi and will flood at anything above 7 psi.

Q: where is it made/does it have a poylmer diapham to hold up to heat & ethenol?

Ethanol is a problem in many situations.

Q: Does this pump fit a 1963 Chevy 327 , 250 h.p. Block ?

Yes, it fits, though fabrication of lines in and out might be necessary.

Q: Will this fit on a 350 sbc?

Yes, absolutely. If it’s 1986 or older block with a fuel pump provision, or an aftermarket performance block 🏁

For 4BBL Carburetors.

The MF0001 Inlet size is for 3/8" ID fuel hose. Outlet size is for 3/8" flared tubing (5/8" line wrench), same as the inlets on Holley or Quadrojet 4 barrel carburetors and not for the 5/16" flare tubing Inlets on Rochester 2 barrel carburetor. The MF0020 pump is the 5/16 x 5/16 Inlet/Outlet pump.

Didn't cost to much

Ok. I put this pump on my sbc 350 this morning. and it works great. to great for some reason it's putting out 2 1/2 times the psi almost 15 psi. that is way to much for my carburetor which 6.5 is max I can run it. It will blow out my needle and seats. Luckily I only paid $16 bucks. Is it worth it to send it back. I don't know.

Reliable

This went on a daily driver so it had to be reliable. It’s been installed for years and still functions like new. Doesn’t loose prime unless it sits for several days. Starts right up every morning and never had a vapor lock issue. Excellent value for the money.
