    I would not run it with a 1 gal fuel cell in the front... you will need at least a 3 gal in the front... I ran a simular set up a while back. had a 8 or a 10 gal in the back. BG 280 pump and 2 fuel bowls mounted on the front tank. Do a burn out and turn everything off and check you front tank, tell us how much fuel you have in the front tank.

    i had a surge tank with the holley fuel bowls when i sent everything to spud to be flowed..he told me to get rid of it [said fuel bowls restrick fuel inlet from rear tank..said couldn't get a big enough needles to keep front tank full]and go with a straight 1 gal[least i should run]fuel cell then feed it from rear tank using a aeromotive A2000 pump[said that was only one he was sure of flow ratings and it was size i needed..also said i don't want to pressureize front tank so i was to modify front tank where inlet from rear tank was level or slightly lower then the return from front tank to run back to rear tank;;said the rear pump would run non stop keeping front tank full dueing a 1/4 mile past..but didn't tell me how much fuel i'll use or need for each pass

    I'm no expert, but with the setup you listed, I would think that you're going to burn up a minimum of 5 gallons on a run and a couple more on the burn out so you are looking at around 7 gallons per run. As you start pushing for more hp, you're going to burn more fuel.

    I would think that a 10 gallon tank as a minimum and you don't have to fill it up all the way.

    I would rather have fuel left over in a bigger tank after a run than running out of fuel from a smaller tank, your motor will thank you for it.;)
