Fuel Pump replacement

[HSFDChief600]

So I had to replace the fuel pump on our truck that we use for a brush truck. We decided to replace the manual pump with an electric pump. Got it all hooked up and powered up. Truck runs for a second or 2 then dies. The pump puts out like 9-10 psi so it should be plenty of pressure to run it. Just wondering if anyone else has had this issue?

Are you sure you were able to bleed all the air out of the system?

How did you plumb it up? If you screwed up and plumbed it to the injection pump return, or in some other way that would put back pressure on the return it would run as you described.

It's plumbed correctly, acts like it's not getting enough fuel or has air in the system somewhere. I'm starting to think I have the pump too high in relation to the fuel tank. I have been sick as a dog so have not worked on it much.
