4BD1T - Zexel Lift Pump Overhaul

[kennyg]

Hi there,
I have identified a leak on the discharge side of the lift pump (ZEXEL PN:105210-6130)
It appears to be coming from the base thread into pump body which must have an o-ring/gasket.
Has anyone purchased the overhaul kits? I would like to try repair myself, if anyone has any tips/tricks please let me know.

While you are doing that, maybe replace the priming pump with the Bosch unit:

Ive used them.

not a lot to it, other than the 4x4 inlet is a bit of a bugger to get setup and pull, I generally disconnect the line clamp and hose then take the pump off as one with the hose on the bottom

1/4 inch drive socket set for most of the work

assemble with rubber grease on all the moving parts (or grease or petroleum jelly) little smear of thread sealer on the threads, clean the secret hidden filter in the inlet, copper wire wheel and brush to clean the insides of the pump assembly and thats about it.

have fun.

oh also..

make sure the vehicle is nose up hill and the tank is less than half full.
