went carburated on my 92 and have a aerometer fuel regulator.I'm using the stock fuel pump in the tank hooked to a switch and have the pressure line goin to the regulator then a line from the regulator to the carb.the regulator is for a duel feed so I have the other side blocked off.should I be running the return also? if so how do I run it?? do I use the other side of the regulator??? any comments would be appreciated.

You have to buy a regulater with a return on it,if it were me I would definetely run a return you only need 8p.s.i MAX with a carb and the stock pump puts out alot more than that.You dont want to overwork that pump youll burn it up,you can run the return line to the stock return line that was on the fuel injection.Hope it works out for ya [patriot]

that reg you got is a non return style. so just block the one side off. 2nd. if you want to run a return line. then make sure the return line is smaller than you carb feed line is. or you'll have the same problem i was haveing. the car running out of fuel on the top side. becuase it is easier for the fuel to go back to the tank then go to the carb. and don't run more than 7psi tops! 6psi is better. hope this helps.

I have never done this before but you may run into problems using a high pressure fuel pump with that setup. An EFI fuel system runs at around 40 psi and a carb'd setup is around 8-10psi. That is a pretty significant diff in pressure.

Most people switch to a mechanical fuel pump when going carb'd.

Check that out. Eliminate the in-tank pump, get yourself an external pump and call it a day.
