Fuel tank baffle
Anyone have any pictures of a stock tank cut open? I"m curious how GM baffled it.
I'm doing an EFI conversion. I've been considering welding a sump to the tank, but the angle of the tank in the vehicle means the sump will only be effective really on launch. If I attempt to put the sump at the forward part of the tank (lowest) I feat it might get torn off.
In any event, I'm curious how the general did it.

Re: Fuel tank baffle
drill 5 holes in the bottom of the tank like a dice would have on it and weld the sump in the bottom rear ward most area in the center. That will be a poor mans baffle, either way you can't run the tank nearly dry because in a turn it'll become uncovered and you'll suck air.

Re: Fuel tank baffle
my jegs sump is definitely the lowest part of my tank setup, that pic is possibly just a weird angle. I cut off both -8 fittings and ran a -10 though on my setup. I'd weld in the largest fitting you think you'll ever need before welding it to the tank. What is this ripped off comment about? Maybe I'm not understanding you, but if your tank ever touched the pavement the rear end would have to be missing first.

So these guys put the sump in the back which is probably fine for drag racing, but it's not any lower than the front of the tank is (lowest spot) so I'm not sure how well it will work for cornering or stopping. I'm weary of sumping the lower part of the tank because I think it will hang down to the point where a speed bump might grab it.
Or maybe it's just me...

Re: Fuel tank baffle
Still curious if someone has a pic of the inside of a thirdgen tank baffle setup.
