I have a used Robb MC fuel pump, regulator, and pre-filter setup. I ran this on a street car for 5 years, removed in 2017 when I installed injection. No issues with any of the parts.

This is the 'upgraded' pump and the regulator requires a return line.

Asking $125 for the pump, $40 for regulator, $25 for prefilter

Also have a fuel sender for 68-72 A-body with 1/2" hose connections, $50.

$200 for entire package.

All prices plus shipping.

just curious, did you run a true return line with that regulator & pump? always thought you couldnt use a return with a mechanical pump, just the vapor return robbmc offers for their pumps.

The regulator that I bought has an 1/8" NPT bypass port. I ran a 1/4" hose back to the tank. The sender assembly had a return line built in, so it made it pretty easy. I didn't actually run a return line from the fuel pump, it was from the regulator.

i understand the return was on the regulator, i thought a true fuel return line wasnt supposed to be used with a mech pump. the one that robbmc sells that installs on the pump is a vapor return.

here is what i remember reading & having rob explain. the return regulator is only intended for elect pumps, mech pumps arent designed to use a real fuel return line, but like i said it may have functioned ok but the psi & flow would have been reduced a lot. i was just curious when i saw a big full return line hooked up to the regulator.

edit: after looking more at your pic, that "return" fitting/hose is connected to the gauge port, not one of the bigger openings designed to be a return.

i have the 1100 pump & regulator, robbmc parts are very high quality & this package for sale is a great deal.
