Fuel Pump Woes

NEW PROJECT:
Replace Fuel Pump

ISSUE:
40 dollar, electric fuel pump from auto zone that is graded for 4 cyl and 6 cyl was put on the jeep before I bought it.
It is leaking fuel

SOLUTION:
replace electric fuel pump with mechanical fuel pump

PURCHASED:
http://www.partsgeek.com/gbproducts/...FUUV7AodmEMAnw

PROBLEM:
The damn thing will not fit because the power steering does not grant enough room for the pump to slide into the engine block, and fit behind the power steering fluid reservoir.

THOUGHTS?
Now what....

The power steering pump sounds to be in the wrong place hence the need for the electric pump. Normally the alternator is on that side of the engine granting lots of room for the pump.

Ok I took the power steering pump off and it appears I can fit it...

HOWEVER - I notice when sliding the mechanical pump in I have a hard time getting it to flush up against the block? Could this be due in part to the cam being in a position that is making it impossible to load the lever of the pump inside the block? If that is the problem how in the heck do I fix that?!?!

Thanks
JP

Just "bump" the starter, the cam will turn and it will slide right in: at least that is what worked on my install.

Yes that us how it works. You either use the bolts to pull the pump in or rotate the engine so the pump hits a lower spot on the cam.

Also remember, there are two pumps used an AMC motors. One is facing upward, and the other faces downward.



Mine when I was building my motor...

The part on the cam,called the eccentric,could also be worn. This is not uncommon. An electric pump may have been the solution at the time. Hopefully this is not the case,but be prepared.
