This has been resolved

Connected a VL turbo EFI fuel pump direct to the carby because the the stock carby fp couldnt keep up

don't forget to call me when everything's sorted out

eerrmm... the carb will only need 3~5psi pressure.

you havent found that the pump is overpowering the float and over filling the fuel bowl??

[ke70dave]

that poor little carby will be getting OWNED by that fuel pump.

btw how does that 4ac go? sounds fairly intense.

are you still running the stocko carby?

[Javal]

Yeah man, a VL EFI pump is going to cause you alot of trouble.

You'll want an electric pump for a carby (aftermarket example is a holley pump) / lift only pump. as mentioned before 3-4psi is the most that's required.

high power 4ac??? is that posible? ha ha

but serioulsy how much pwer do you think this will make? are you doing this for a certine race class?

[rthy]

haha in all seriousness

the std fuelpump couldn't build enough air pressure to suck up the petrol from empty lines just buy cranking with the starter motor...

so i used a spare vl fuel pump to suck the petrol up the massive 6mm copper lines
now starts 1st crank :) its sounds so sexy with out any extractors
ill put a video up
