Also, Carb intake was what I was referencing not running well; fowling plugs. like I said, back to the stock Vortec truck intake:
Fuel system will be a 1987 Fuel Tank and pump set up; pump puts out 135 PSI and the tank is baffled; 200.oo set up from Rock Auto.
Fuel out-efi Hose to 10 or 40 Micron inline. 3/8" Not to hose barb input; Braid 6 AN to the inlet on the intake. return line I think is 5/16 and low pre4ssure so I will probably run 5/16 EFI hose to the pump return; not sure if I have enough room for tube to AN crush fittings. I will try and post my results.
