A 1/2" (or -8AN) return line to a RobbMc 1/2" sending unit will work fine. When using a bypass/return style regulator, ALL the unused fuel is returned to the tank (unlike a bleed or "vapor return" line which only sends a small amount back to the tank to keep things cooler). So when using a...

A 140 pump with a return/bypass regulator will require a 1/2" or larger return line from the regulator back to the fuel tank. You'll need to either change to a fuel cell or figure out some way to adapt a 1/2" return line to your stock fuel tank. This is why we developed the PowerSurge units. No...

You are confusing our mechanical pumps with the PowerSurge units. The 550HP and 1100HP pumps are mechanical pumps. The PowerSurge 500 and PowerSurge 1000 are surge tanks with electric fuel pumps inside. The instructions for the PowerSurge units can be found at the bottom of this page...

One Walbro 255LPH pump in the PowerSurge 500 and two in the PowerSurge 1000. You said: "It also says if you do not use a regulator with the pump and lower the fuel pressure the flow will be reduced by 50%. 50% of What???" I'm not sure where you read that but it has nothing to do with the...

Coarse filter (about 100 micron) before the pump (to keep the big chunks out of the pump without putting too much restriction on the suction side), and a finer filter (about 40 micron) after the pump to protect the carb. The factory did this with a "sock" filter in the tank and an inline filter...

Very quiet and you don't need to change the rest of the fuel system: http://www.robbmcperformance.com/products/powersurge.html

We hope to have our 110 and 220 gph six valve mechanical fuel pumps available for SB and BB Mopar V8 engines in April. Go here to see examples of the pumps we are already making for other non-Chevy engines: www.robbmcperformance.com
