On a carbed engine with an electric fuel pump, is there any reason why I can't plumb the return line from the regulator back into the feed line from the tank before the pump?

Re: Fuel return lines
Sounds easy enough,, but why? Low pressure ... You are just making more places for leaks.. Once it's pressurized it's just more tubbing holding gas..KK6DAD

Re: Fuel return lines
So if it's only an 8-15 lbs pump it's not enough to worry about back pressure and damaging the pump?67 Bronco blue - LS 6.0, 6l90, & atlas (working on it)

Re: Fuel return lines
Thats what I say.. You are not reducing pressure unless you return all the way to the tank. Or at least before the fuel pump.other than that it just builds to max pressure and stays..KK6DAD
