thank you for the info.. wanting to use some of the stock parts if I can.

 

What fuel pump will you be running though? Most have to run new power and ground wires to support the power loads.

 

yes I have to Upgrade the fuel pump Power Edelbrock pump 1794 120gph 12an in and out. but I can still use the fuel tank sending unit wire ..Just 1 pump..I like to have back ups..just in case..

 

Make sure that any filters used past the Fuel Pumps can handle the Flow of the Fuel Pumps...
Do not use a filter that flows significantly less than the Pumps, it can create a restriction.

 

Yes..all filters are set to flow more them the pump ..
