I have a stock 5.3 fuel regulator on the fuel rail, so I have both the pressure and return lines running to the engine.
I have a new switching valve which is rated for mid-60s psi and it plugs into the stock 87 wiring harness. I replaced all the lines with gates EFI rubber hose from the tanks to the switch valve, and then AN line from the switch to the engine.
Lastly I moved the switching valve to the driver side so the lines can run down the driver side of the frame and up to the fuel rail which is on the driver side of my engine. That's not required but its what I did

I am in the process of installing a '13 4.8/4L60E in my '86 and I have 2 of the EP381 to go with my dual new '87 tanks. If I understand right the '87 stock sender will work with the 381?? it sounds like the above is what I want to do as well??
thanks!!
