    The walbro gsl 392 is a inexpensive serious flowing pump.

      have you used this pump? Right now I have the factory TBI in tank pump feed a Holley 670 through a pressure regulator. I worry if the factory pump fails, I want something I can put inline..... and perhaps I might have to do it away from home.. LOL

      Yes I have used it before on my hot street 318 with about 350 hp and a 4 speed a few years ago. I think I actually have a brand new one on the shelf with -6 an conversion fittings if you’re interested. I think the standard in/output on those pumps are a 10mm if memory serves me well.

        they push around 60 psi. I have a regulator already. Do they need the return line? Thanks

        I ran a return line yes. 3/8 feed, 3/8 return is what I ran. I have found running a return really helps solved most fuel related issues.

          I have the Holley(Mr. Gasket is the same) Mighty Mite,Jegs part # 510-12-426.
          Installed it on my 79 Chrysler with a 360 Thermoquad.The mechanical will pull thru with out any problem.At first I just wanted it for a primer but for fun I removed the mechanical pump to see if it would run and keep up with the engine needs.
          It did,no problem.Tested it for 100 miles then reinstalled the mechanical and just used it as a primer. The above part # is for the 1.5 to 4 psi.I now have the #510-12-427 pump that is a 4to7 psi and is rated up to 400 hp on my 63 Belvedere with a worked 318.It too is used as a primer and I'll click it on if I get to run it thru the gears. Not a bad tiny pump for about $50.Also it can be barely heard with the engine running going down the road.

              question is, would this be the best choice to carry in a '89 Van that came with a TBI, but now is using that factory in tank fuel pump to feed a Holley on a 360 magnum. Looking for something to carry with me incase the tank pump goes out, I can plumb in the inline electric pump and continue my journey.

              this pump will work perfect with TBI and is very quiet and have np feeding a 360 magnum . as far as the best choice goes I dunno I'm really not that smart .

                What did you use for filters before and after the pump? I was thinking about getting one of the walbro pumps to feed my carbed 360 magnum.

                  I use the red Edelbrock one to feed my dual quads and I've never had any starvation issues at the track or anyting. I actually use one for siphoning gas back and forth with some long leads and some hoses...

                  glad you said that. I actually had the red edelbrock pump in my hand today at O'reilly's (60 bucks) looking at it. Did you run a return on your car? Or just have it end at the carbs? the package said 5-7 psi, do you run a regulator?? Thanks

                    That's the one... No return line just straight into the carbs... Their fuel pump and their carburetor.. I thought it was a little cheaper than that though...

                        so you've been running that pump for about 5 years? And did you hook it up to a toggle switch or your ignition? Oh, and are you running a regulator?

                          I've been running it for a couple years now ever since I got tired of that loud ass million gallon per second fuel pump and regulator... No regulator.. also it's not in the back of the car it's in the engine compartment about three feet from the carburetors.. on a toggle switch in my row of switches where the heater controls used to be...

                            you still running the factory gas tank or a fuel cell. Wondering how it pulls gas from the tank after your car sits a while and the carbs go dry...

                              You're just looking for a backup to get you home correct? Or finish your trip I think you'll be fine and if it breaks you can find another one at the next orielys...

                                Don't forget safety regardless of what you do. I plan on wiring in a Ford fuel pump inertia switch. In the event of an impact, the switch throws and cuts off power to the pump. Three wire connection.

                                  It wouldn't work for me... oh, it would cut off the gas everytime I bang gears with that neck snapping inertia...

                                    I'm close to just making the in-tank pump a sending unit, put a eccentric on the cam and use the mechanical pump. End all the nonsense...

                                    I certainly don't see the need for an electric pump in your case.....although they are nice for solving vapor lock due to ethanol in fuel.

                                      before I'm confident in going across the United States, per say, I need to feel good about the fuel system and electronic ignition system he used to set this up. For ignition he used one of those ebay ready to run HEI distributors/coil from china. Thought about points, and the coil that doesn't need a ballast resistor.
