do a search on it, but it has been recommended that you use studs instead of the trying to get the bolts started. if i can find the size you need i'll post them for you. good luck

Buy a pair of studs with nuts to replace the stock lift pump bolts and the job will be a hundred times easier.
Size is 8mm x 30mm x 1.25 pitch. Most auto parts carry them.

Does anyone know if you can replace the rubber boot on the lift pump. On my 94/12v 189000 miles it has split.
Thanks

The only part that available for the lift pump is the o-ring behind the primer button.
Only way you'll get a new boot is off a used pump.

Put the top line into the lift pump, and give the nut enough turns so it's started for sure. Then throw it on. Install is a breeze, I thought. But it might be different on a Dodge.

Not to hijack, but after the install, my truck was much quieter. I could hardly hear the engine if I was running the heater. Why is that?
