quote mikephillips:
I’m not sure you even can mount the fuel pump upside down. The pump is operated by an arm that rides on a cam lobe which I believe is slightly offset towards the bottom of the pump mounting hole and studs. And even if you could that would put the inlet facing the front of the engine when the fuel line comes in from the back.
Agreed, Mike, unless it was designed to go on bowlside down. With your information, I’m sure that if one were able to mount it upside down, the motion of the cam would probably tear the pump arm off and cause all sorts of internal damage. Like I said, I got a little paranoid and needed a bit of "hand holding". 😳
Thanks again
