white86turboz Posted February 24, 2005 Author Share Posted February 24, 2005 Whats the difference between the 2? I just need a 255 Walbro fuel pump. I'll check out ebay. Thanks Quote Link to comment Share on other sites More sharing options...
auxilary Posted February 24, 2005 Share Posted February 24, 2005 inline = external universal unit in-tank = internal unit, application specific to the vehicle. Quote Link to comment Share on other sites More sharing options...
Z-Gad Posted February 24, 2005 Share Posted February 24, 2005 I know I have posted this before, but not all Walbro 255lph fuel pumps are created equal. If you want the inline pump, then the part number is GSL-392 for the high pressure, high volume pump.

lifegrddude Posted February 24, 2005 Share Posted February 24, 2005 While we're on the subject of Walbro pumps, I am going to replace my dead pump with a Walbro and I'm curious to know if the Walbro is going to increase fuel pressure above stock from the old pump. (ZXT pump) I don't have an adjustable pressure regulator yet (saving up for it). Do I need to adjust the AFM settings aka will the Walbro make me run any richer at idle and cruising if it does increase fuel pressure? Thanks.

white86turboz Posted February 24, 2005 Author Share Posted February 24, 2005 I'm thinking of just buying a universal unit since there's no specific application for my car. Man the list never ends when upgrading a turbo car. Quote Link to comment Share on other sites More sharing options...

white86turboz Posted February 24, 2005 Author Share Posted February 24, 2005 So when I get the Walbro fuel pump, then I should also upgrade the fuel regulator then, are there universal regulators out there? Ebay has a lot of big V8 fuel regulators, but is that what I need? Quote Link to comment Share on other sites More sharing options...

white86turboz Posted February 24, 2005 Author Share Posted February 24, 2005 LOL Ok yeah I didn't really read that, stock fuel regulator it is. I heard a ajustible fuel regulator might be a good upgrade in the future, but I'm not worring about that right now. Anyone have a AFC they want to sell?

I would spend the extra $20 and get the install kit to make it easier to install. I know 87-88 300ZX turbos have intank pumps, I would think they are all the same but not 100% sure. You don't need an adjustable or aftermarket regulator. Quote Link to comment Share on other sites More sharing options...
HeatRaveR Posted February 25, 2005 Share Posted February 25, 2005 Is there any benefit to having the pump in-tank vs. external? Like, is it "safer" to have the pump in-tank or something? Quote Link to comment Share on other sites More sharing options...
randy 77zt Posted March 5, 2005 Share Posted March 5, 2005 most newer cars have the pump hanging off of the fuel sender with a sock on the bottem to strain the fuel.pump and tank are installed as an assembly -its faster at the factory .hoses have snap on connectors and 1 plug for the wiring.older cars like 75 up z with efi had an EXTERNAL pump mounted to the body of the car with a hose feeding the pump.pump had to be mounted low so it would pick up fuel.i am installing a walbro gsl392 external inline pump on my 77 z.the threads on the walbro pump require you to buy adaptor fittings.i am running a 12mm hose barb on the inlet and a adaptor for 6an hose on the outlet side.i am building a custom fuel rail with an fittings.fuel system pressure side will be 6an or equal to 3/8 line.i have heard 5/16 line is good for up to 400hp at 40 psi so the 6an should not ever be maxed out with a l28 motor.
