bunkyT18, yes there is a dash mounted switch for the fuel pumps. there is a fuel pump relay controled by the ecu, this i have controling the lift pump. i take a signal from this relay to the dash mounted switch, which then switches on one of the two main fuel pump relays.
each main pump relay has a fused power source deirectly from the battery. so when i turn the ignition on, the efi relay siwtches the lift pump on, and one of the VL pumps. there is not a metered amperage, just a constant supply from the battery to the VL pumps. i was under the impresion all electric fuel pumps just had a direct power supply and would draw whatever current necessary, maybe im wrong?
ChrisTH, in my situation its not a matter of dirt in the tank as there is a filter before the surge, its DEFINATELY temp related.
shinybluesteel, why should the tank feed be at the bottom of the surge? i cant see how it would make a difference.
over next week i will obtain a higher flowing lift pump (just for piece of mind) and run the return line to the main tank and just block off the top surge tank line. im fairly confident this should fix it, wanna get it sorted by megacruise
