Hi all! I hope this is the right forum for this question.

I have an external in-line fuel pump for the 1989 F-150. I'm using it for a custom fuel injection system on a supercharged motorcycle (yes, i'm nuts). Can someone here tell me which end of the pump is the high pressure (fuel rail) end? Is it the end with the electrical connectors on it? Thanks in advance!

?? I had a 1985 Ranger and it had two fuel pumps on it. One in the tank, high pressure pump. One on the inside of the frame rail under the drivers door this was a low pressure fuel pump. Are you sure your not looking at a low pressure pump and the high pressure pump is in the tank?

 

this is the pump:

i know it's the right pump for what i'm doing, i just don't know which is the tank end and which is the fuel rail end. if anyone knows that'd be awesome.

Question that would be obvious. Does it have an arrow on it that would shows the direction?

 

hook it up and try it. if it dosent work, turn it around.

 

On my 1987 F150 fith 5.0L v-8 the output (pressure) side is the one with the electrical connections
