Yup cant find one, i found one for a 94 yj 4.0 look identical is there any difference? or has anyone found one?
The part i found is
5003861AA

I took off the fuel line off the rail and ran it into a bottle when u turn the key it would randomly not send fuel, so im assuming sending unit is dying , fuel pump is a bosch and brand new not saying new cant mean "never ever worked" however it seems to be getting progressivly worse with time so i think the sending unit is dying

 

I don't know if the XJ and YJ use the same pump. The one you want is Bosch Part # 67617 provided you want the complete assembly. You can change just the pump and re-use the housing too.

Before you shell out $, check to see if you have solid power going to the pump. Grab a DVM, probe the power connector at the pump housing and see is going on when the pump acts up. Might not be the pump at all.
