machanical fuel pump

I am looking for someone that has used a carter 170gph machanical fuel pump

I'm getting ready to redo my fuel system and I was woundering if the carter 170 gph machanical fuel pump has any fitment problems in a 69 camaro with a 350 sbc.The carter 170gph pump looks very large in size.does this pump hit the chassis? or any other problems!!

Re: machanical fuel pump

i've got a holley 170 gph in my 69 with a big block. i don't know about the carters but on my holley the bottom half can be unscrewed and rotated to point the inlet and outlet whatever direction you want. i'd imagine you won't have any problems with one on a small block.

Re: machanical fuel pump

I'm using a Carter mechanical pump, it has female 1/4" NPT outlets in which you need to use a male 1/4" NPT to 3/8" or universal nipple for the rubber line on the inlet side and the same for the outlet side, (unless, like me,you run a 3/8" hard line then you need a 1/4" NPT to a 3/8" Inverted flare. You can bend the line yourself and flare it, aluminum is easier to work with than steel).
But the Carter also allows you to unscrew the bottom to rotate the bottom of the housing and point the outlets where needed for correct alignment with fuel lines and no fitment problems with chasis. Provides about 6-8 psi.

I am running a Barry Grant superspeedway mech., which is pretty much the exact same thing, and it has plenty of room all around. Even using larger -8 An fittings.
Ditto on the abilty to "clock" the bottom of the pump to suit your needs with the BG.

Re: machanical fuel pump

Tried one here and the lower clockable half was still too large , as the lower half hit the frame. Went to Edlebrock with a smaller id lower clockable half and cleared . Be careful using hi psi pumps with out going to brass tipped push rods. After a few hundred miles, I had to go carter electric as my fuel pump lobe said goodbye on my hydra roller.
