electric fuel pump

any one know how to adjust the regulator please???

a fuel gauge between your reg and carby is recommended to measure your pressure, but from memory, i beieve you'll need to back off the nut, then screw the tread out (anticlockwise) to increase flow/pressure...

so i would have it the wrong way round.....

thank you

ive been reading, and i found the holley brochure online, it says clockwise to increase pressure....

hey mate i have one in my 308 vk, and they are pretty reliable, but it may be an overkill for a 253, but if you do get one , make sure you get a regulator, and set it to 4- 4.5psi, goodluck

is 4 - 4.5psi enough?

one of my mates told me 7psi....

what do you guys and gals think

thanks

Somewhere between 4.35 (30kpa) to 5.8 (40kpa) is what it should be between. Probably around the 5.5psi would be best.

cheers

lucky i got the fuel pressure gauge.... i was running 11psi... when i turned it down, the engine sounded very different......i left the pressure at 6.5psi , where i thought the engine sounded like it was running the best.......
