Delphi MF0001 Mechanical Fuel Pump

No issues , works well.Only ran motor for 2 minutes but looks / works good in that test run.

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.

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.

It works great

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.
