Doomed To Have Problems

[Grumpy]

Hi, Im running a 3/8 fuel line from gas tank to 454 6:71 blower but only have a 5/16 sending unit connection at the tank. I have a 110 gph elect fuel pump and don't know if the elect pump can suck enough through the sending unit or not and if it could ,would it matter where in the 3/8 line the pump were located.
thanks jim

electric pumps push fuel far more efficiently than they (suck fuel)
some won.t even reliably self prime if not lower than the fuel level., or in the fuel tank designs

Up to 45 GPH= 3/4 GPM = 5/16" or -04 AN
*
Up to 90 GPH = 1.5 GPM= 3/8" or -06 AN
*
Up to 250 GPH =4.2 GPM= 1/2" or -08 AN
Use these figures as a fuel line sizing standard: if your feeding a carburetor with the typical 8-10 psi fuel pump feeding to the fuel pressure regulator
* Up to 250 HP = 5/16" or -04 AN
* Up to 500 HP = 3/8" or -06 AN
* Up to 700 HP = 1/2" or -08 AN
