mechanical fuel pump

I know when my fuel pump went, (on the beach while driving ) i found out that the filter got knocked off the fuel pump, which would leave me to believe that it would throw some kind of error code and shut the unit off.

any reason why a mechanical fuel pump wont pull through an electric thats in the tank, with no power running to it?? i was getting fuel at first, enough to start the jeep. now nothing. maybe a vacuum or something. so confused!!!!

what jeep your yj? what engine?

I had my mechanical fuel pump pulling through an electric fuel pump that sat on my frame rail. I never had a problem with it but I imagine it would be dependant on the specific electric fuel pump. Try it out.

Why are you going back to mechanical?

ok... seems to me, looking at the lever... its supposed to be on top of the cam, not underneath... anyone know for sure???

Isn't one side smooth and the other not?

Like in this pic the top would be smooth and the bottom would be channel.

this is the exact one... cam underneath the lever right?

Assuming it can only mount one way, then yes.

The parts drawing shows it mounted like your pic, with the fittings up.

Depends on how it's spring loaded. You want the spring to continuously push against the cam so that the lever stays in constant contact. I'm pretty sure the lever rides on top of the cam.

Yes over the cam and yes pointin up like your drawing.
Is this a old pump that was conviently plugging the hole that you decided to use because the electric one stoped working ,or is this a new pump?

Monitor the fuel pressure as it primes and kicks off.
