GSL-SE Fuel Pump Questions

Once again, I couldnt find the answers searching, so if you would be so kind as to answer the following questions, I would be very happy. Thanks .

1. I know the fittings on the gas tank of an -SE are different than the non -SE cars, so are the fittings on the pump different as well?

2. Does the -SE pump mount the same way in the car as the non -SE pump?

3. Since Im putting an -SE pump in a non -SE car, should I use the -SE fuel filter, or will the stock non -SE filter be ok with the higher pressure? Is it just the shape of the filter thats different?

Once again, thanks, and I hope someone knows the answers .

The pump mounts in the same place, dunno if its exactly the sam bracket though. WTF are you up to? Why use an SE pump in a non-SE?

1. the feed line is huge on a gsl-se, the exit of the pump is the normal size
3. you need a filter for fuel injection, the plastic jobber might pop, its not designed for high pressure

Well Carl...

Actually, Im going to use the -SE pump to provide enough (more than enough) fuel for my Weber carb rather than buy an aftermarket pump. The idea being that I plan on building a turbo setup sometime soon, which means I need an even better pump. The -SE pump should work well, and its only $10 at the junk yard .

So you guys say that Im gonna need to do what? Get a different inlet to the pump from the tank or get some adapters or something? Im also gonna need to get the fuel filter for it?

And youll need high pressure fuel lines/clamps/connectors. And the FPR youll need will probably cost more than a good aftermarket pump for a carb'd car.........Carter Carter Carter Carter Carter Carter Carter Carter Carter Carter Carter Carter Carter Carter Carter Carter Carter Carter

You cant run a carb with 40psi man.

Grrrr...I had a whole thread about this and people said the -SE pump was fine . I need something that runs over 7 PSI like the Carter pumps dude. Im gonna run a turbo eventually, so I need a little more oomph from the pump. Im using a Mallory 4309 RRFPR that should work just fine with the -SE pump (in theroy) and is adjustable from 3-12 PSI.
The 3-port return-style fuel pressure regulator is designed to regulate fuel pressure between high pressure fuel pumps and carburetors or fuel injection systems.
It sounds like it should work to me...

i agree, i'm using the -SE pump on mine. havent tried it out yet though cause i'm still waiting on my trailing ignitor to come in the mail. it's all hooked up nice though, i just changed all the lines out. i'll eventually get the -SE fuel tank as well.

Ok, in a turbo application, the SE pump should be fine as long as you dont over stress it (remember its a stock pump, so no F&F 800hp motor will run off it LOL). Now your regulator......................... No good for a turbo. You need one that changes fuel pressure as boost changes. I forget what its called (rising rate?), but that reg you got there wont work with a turbo. Also I wouldnt reccomend it with a Nikki carb, the low end of its range is too high (3psi). I dunno squat about webers, etc, so it maybe ok for them. IIRC they run at about 4-4.5 psi????

Yeah, 4.5-5 PSI, and that Mallory IS in fact a RRFPR (Rising Rate Fuel Pressure Regulator), it just isnt advertised very well. I called and asked . So I think Im basically set .

I might be getting the tank too, but I dont know yet. Since Im getting the carb before the rest of the stuff, I was thinking about just slapping the Weber on there and then running it with the stock pump for a little while (just until my order from Summit Racing comes in). Then, I can put on the new regulator, gauge, pump, etc. later when I get it all. The stock pump should be decent for a little while. Hell, RB said that the stock pump will feed a 48 DHLA Dellorto for up to XX amount of timea t full throttle. That should be good for me cause I dont go rocketing around anywhere for now with so many tickets.

Here ya go TJ. Saw this and thought of your thread.

Wonder what you think about this one.

I'm thinking about using this on a TII Fb instead of the GSLSE pump.

Probably too much pressure if your using a carb.

Thanks man, but it doesnt give me any pressure specs . I wouldnt buy it unless I had some real specs listed somewhere.
