I am ready to fire the engine and was wondering if a "Fuel Return" line should be coming from the fuel injection back to the cell.? The car I have did not have anything resembling this.

Thanks for any help.

Maybe to prevent a lot of wasted time in posting here please feel free to call me, I probably will have additional questions if their should be return line.

As long as you are using all the factory fuel components, then it's fine. the no-return systems use a regulator that is part of the pump in the tank.

Thanks Mike, but I am not using the factory tank unfortunately. I have a 4 gallon Pony Cell and an external pump

It depends on how your engine is equipped. Is there a factory regulator at the engine end? Most of the older cars had a regulator either on the throttle body if it was a TBI design or on the end of the fuel rail if it was a multi port injection design. If either is the case, then yes, you need a fuel return line. This is how the regulator bleeds off the excess pressure.

If it's a newer style where the original factory system had the regulator in the tank, these had a pressure bleed off in the tank. If this describes your car, then you will have to incorporate some sort of regulator and pressure return. Some regulators may be able to function without a pressure return, but I suspect there would be too much pressure momentarily until the injectors are able to bleed off the pressure. This would result in a "too rich" condition for a short time.

Thanks Maurice.

I am using a 1997 DOHC 2.0 liter Dodge Neon. My understanding is that the pressure relief is incorporated into the internal pump in the tank. Is there an external fuel pump made that has the relief feature built into the pump?

I used an adjustable pressure regulator with a return line from regulator back to fuel cell. So, cell to pump to regulator then 2 lines from regulator, 1 to rail and 1 back to cell. Hope that helps

Thanks guys for all the help.

Whats the chances one of you have a brand name and part number? I call Auotparts stores and get a "deer in head lights" type response.
