![]() Is the srge tank pressurized? Mount a 5psi cracking 1 way valve on the return of the surge tank. It will bleed off vapor and force feed the pump. In that clip you hear cavitation. The pump is creating bubbles and it probably gets warm to the touch.
Do you have it running full speed all the time? Might want to get a pump controller. Sent from my GT-I9505 using Tapatalk |

If air is in the system, it can only be up on top in the tank, but the fittings are almost as high as the roof of he surge tank, so any air should get pushed out to the fuel tank if you ask me. The A1000 is lower than the surge tank, so it should have no issues with cavitation as it's gravity fed by it. No, I don't have a pump controller, so it runs full power. I was thinking going to a Holley 12-1400. I heard comments saying they are pretty much silent. For the price of a controller I have the Holley pump. |

![]() Is it silent ?
Well, you have at least the luxury of room. The holley is a little wider than the A1000 and gets closer to my header. Last edited by Belgian1979vette; 06-24-2014 at 09:44 PM.. |

![]() Hey TT what 5 psi backpressure valve do you use? I'd like to build a little back pressure in my surge tank. The tank is not readily accessable (PIA to get to)so I'd like to use a proven piece. Do you have a maker and part#?
Thanks, Grampy |

![]() If the return line is smaller than the feed line, inevitably it will build some pressure. Starting the low pressure feed pump on mine, I can see the needle move some on the fuel pressure regulator, so it does provide pressure.
