Is the GSL fuel tank the same as the GSL SE tank?



How can you tell if its a GSL SE tank?

I don't think that they are the same tank. But I am not exactly sure. However I do know that the SE tank has baffles and a larger pick up. If I were you I would drop the tank and check the size of pick up that is on your current tank.



With your hp and turbo setup you will need the baffle so that when you are boosting you won't run lean and the larger pickup for the pump. Aeromotive "requires" 10AN line for the low pressure side. (tank to the pump)



Good luck

Z....

Yeah the 79 tank wont do for my application. I think I have a gsl tank in the back yard, and possibly a gsl se tank, but not sure which one is which...lol The fuel lines are big enough, but not the pick up.



I need to do the change before abf if possible, so if anyone just happens to have a gsl se tank, please let me know.



Im considering tearing apart IoTus to get my car working right since its a gsl se, and if possible don't really want to do that.

If the GSL-SE has a fuel pump in the tank then they would be totally differant I would think because of the high pressure pump.







You could keep your fuel tank setup if you had a low pressure pump at the fuel tank and a fuel surge tank between the Low pressure and high pressure pumps.

Lucky for me im a parts saving *****. I found a GSL SE tank in my pile of parts. now i have to try to change the size of the pickup line. while im at it im gonna change the size of the return also.

no the gsl-se does not have an in tank pump...

Gsl-se fuel puck up is 1/2 an inch and all 12a cars were 3/8th's inch. the return on se was 3/8ths and the return on all 12a cars was 5/16's.

So will a gsl tank feed a webber 13b? not as much fuel pressure required...... right?

for Iotus you should be completely fine using a 12a tank for her because less HP and fuel pressure. So if it came down to it you "could" take Iotus' tank and put one of your GSL tanks in her.

Yep It's good up to 250 hp I think. That's what I'm running with my blow through. ANd thats what I ran carbed. the return istoo small to run a return stye regulator though. I had to get some 3/8 inch copper tube and bend it from engine bay back to the tank there it's the stock 5/16ths for only about 4 inches.

Iotus's tank is very clean....so were putting it on Blue now and exchanging a gsl tank for Iotus. Should be done soon...will see how it works https://www.nopistons.com/forums/pub...1047683894.gif

if you dont swap all the hardlines from the tank to the firewall it will be pointless. the hardlines are the same size as the pickup on the gsl-se the 12a hardlines are tiny

/\ /\ /\ Ture True!! /\ /\ /\

Well the change went over great, it took most of the day.

And yes the GSL SE has a 1/2 inch feeder tube. I was shocked to seethe size difference between the two tanks.



The SA has a bigger spare tire tray than the FB, so you have to use longer bolts to get it to fit right.

anyways it all worked out in the end. The car idles way better now. You can totaly tell the difference just from changing the tank.



I would like the thank Jesse and Brian, for spending their day helping me figure it out.



I think jesse had the most fun....

Damm Jesse.....

you eastsiders have too much fun. And your cars are all shiney now! What gives?!

Nice to hear that the tank swap went well. Now Blue can get all the fuel she craves!

I hope that doesn't cause problems for ioTus. I remember when we were putting it together, Robert from Rotary Shack was very glad that everything was going into a GSL-SE because of the large fuel tank and stuff... suppose you could get another one if you had to. *shrugs*

i think IOTUS has always been the RED HEADED STEP CHILD anyways.

The pick up line on a gsl is fine for IoTus's carbed application. IoTus doesnt have near as much power as Blue has now. It was either sacrifice Blue not running right, or doing this change over that is fine for both cars. IoTus is running just fine still.



IoTus has had to have a lot of work done to it lately. This summer there are plans for some changes to the car. Stay tuned

Except that it's a TURBOED carb. Hope it doesn't start running too lean now or not get enough fuel at top end. That would be bad...





Really sucks seeing ioTus as the "Red Headed Stepchild" like Kettle said.





What kind of stuff has had to be done to it? Aside from it was leakin a bit of oil out the front cover and the gaskets were replaced? Just curious... been a long long time since I worked on that car. I put my heart and soul into it, so did Geoff.

i cant wait till dave paints his car. its gonna look mean

great way to change the subject

it worked. giggity giggity goo.

cant wait to see that bitch in blaze orange. mm gonna be sexy
