I just got my new Holley mechanical fuel pump delivered today. I havent' had time to start swapping it out yet but I did take a look at the part and sized it up with my old one which is still attached.
This new Holley pump has the in and out on opposite sides.... left and right when facing the pump. It looks like the 'in' is going to compete for space with my oil filter.
My old pump has the in and out rotated very close together but this Holley unit doesn't seem to have the capability of moving the location of the in/out.
Does anyone run a Holley mechanical pump and if you do... did you have issues with the oil filter interfering with the inlet?
They make a adapter that will move the in and out to the bottom of the pump. At least they do for my eldelbrock fuel pump......
