    Phase 1 fuel filter has air

    Giz a hand on this lads!
    Had a bit of leaning out going on at national day, so pulled the car off the track, I'm investigating in to the problem only now as I'm a lazy basted! Lol
    Need to get the car ready for snetterton next month, so I'm starting from the fuel tank forwards, first I removed sender from the tank and everything looks sound, then was under the car checking lines, when I noticed the new plastic seen through fuel filter on my phase 1, was only half full!?
    So I started the car to see what's going on,and it look like a washing machine( air and fuel whooshing around) is this normal ??
    Before I start getting hit with possible running faults I know them, and iv checked all them all, it's got a new fuel pump, carbs good, pressures good and so on, I just want to( for now) stick with the issue of the air in the fuel filter!

    yes the see through filters look like this with the engine / pump running....Id bin it and replace with a metal canister filter as per the ph2. Especially with a track car, I don't like the idea of a brittle plastic fuel filter under the car

    You could always T a fuel pressure / boost gauge into your fuel line at the carb to check your fuel pressure when running, shold be at least 4psi fuel pressure above your boost pressure
