i have a 86 mustang that was a 6cyl. fuel inj. and i swaped it to a 302 carb. i bought a holley fuel reg with bypass from summit and a carb and it ran fine for a week. now it won't stop flooding the carb. i have adj. everything and still does it. my guess is the reg is defective. my question is i am running a holley in tank pump i am not sure if it is the 255 or not i forgot what the guy told me when i bought the tank and pump from him. the reg. is the hly-12-803bp. is this the right reg. for my app or do i need to send this one back and order a diff. is so which one do i need now? thank in advance for the help.
need advice fast.

I sounds like you don't have the correct fuel pump and regulator. I never use a bypass regulator on carb applications and certinaly don't use a fuel injected pump w/ a carb either. do your self a favor and pick up a holley 150hp fuel pump and regulator, and no more wories.
if the pump puts out more than about 14 lbs of pressure, the regulator you have will not work. since it is a f.i. pump i'm almost certian it puts out 2 much pressure!
i called summit and they told me i need to use the mallory fuel reg with return. it is maa-4309. so i am sendin my stuff back and exchangeing it for that one. guess i will see. the old one worked fine til i added more gas in the tank cause i ran out. but i was told to get that one cause i did have a stock fuel pump in the tank but i later found out before i hook stuff up that the old pump was dead and then found a tank full of bad gas and all rust so i bought this guys tank.
