Thread: Which Fuel Pump?

Tweet

Thanks Techinspector I've copied it all down, everone around here told me to get the Holley blue but I'm going with your recommendations. OH one more thing where should I start with the jetting on the Dominator for this engine? Thank's again

Many, many variables. Start at 88. May be too fat. If both power valves are in place, 84-88. If no power valves, 94-96 as a start. CHECK PLUGS OFTEN until you get it jetted the way it wants to be. Go 88, then 86, then 84 if it's fat. You don't want to jump too far at one time and go lean on the motor.

Thanks alot will be back in touch later with some results.

Having just been through the instructions from Edelbrock on their pump and plumbing, I will offer one comment. Edelbrock stresses that the pump be 1) below the tank, as close to the tank as practical, and 2) that there be no filter upstream (other than the OEM "sock" in the tank). Their filter goes downstream of the pump, and Edelbrock's explanation is that the pump is not designed for the added pressure drop of a filter on the pump inlet. Also from Edelbrock, the advice is that even if it works initially the filter pressure drop will increase as the filter ages causing early pump failure, especially on an existing system being upgraded with new components. I'm sure there are many systems installed with filters first, but you might want to check your pump installation instructions relative to warranty and decide accordingly.

I'll be using a 6 gal. fuel cell and I'll install the pump under the bed on the frame and the cell will have the bottom outlet so everything will be down the hill.
