Went out this morning and only had 2-3 psi. I drove it to the store and back, no problem. It was cold last night and I'm due for new fuel filters, maybe some waxing on the dirty filters. Maybe it's my Holly Black fuel pump, it's been in there for about 5 years now and it looks like it is weeping a little on the bottom. I have a rebuilt Holly Black under the back seat. Not sure what to do?

 

First, I would check the fuel line for the gauge, then change the filter(s). Dumping some PS silver in will help if you are gelling a little.

If you have fuel seeping around the pump, the seals may have worn, allowing fuel to get into the pump motor.

 

the cp3 will work and produce full power down to MINUS 5 psi lift pump pressure. the filters are ok. a plugged filter causes low pressure under load, not at idle. the stock in tank pump was the best but I bet you did not keep it. carry you a hose to bypass the pump in case the pump fails, you can bypass it and get back on the road then in the next few months get a brushless pump.

 

I installed a rebuilt Holly Black fuel pump, works good, at start-up it reads 20-21 psi, driving around town 17-18 psi, the highway 14-15 psi.





The pump I just took out was a used Holly Black and I got 4-5 years out of it.





I'm not sure if I should pick up another pump or try and rebuild this one myself. Anyone ever rebuild a Holly pump, any advise?
