Well I just replaced my filter, pump, and sending unit about a month ago. My truck started acting up again so I checked the pressure and it's 50-55 psi . The people at the parts store said you can't replace just the pump, but I found just the pump on ebay will this work? I don't remember what brand the new pump and unit is that I just replaced, but I know it was not ac delco (probably my problem)
Thanks,
Jeff

It would be handy to know the make, model, engine size, and any other relevant information about your truck to help. The best way to accomplish this is to put your truck info in your signature so it's automatically on any post you make.

Looks like Rockauto.com has just the pump. They also have the pump + sending unit. Prices range from $60 - $300.
