    I noticed that on my mate's TT 180 fwd that his pump primes longer, about 3 seconds, that it does on my car with is about 1 second.
    Am i right on thinking that this is something programmed in the ECU and not relays related since it gets its input from the ECU?
    And what can be done to increase it?
    Some might wonder why i'm asking this is that i have a new pump installed and when fuel is around 1/4 tank car doesn't start on first attempt cause i have a bypass in the swirl pot with it gets emptied on such occasion.
