auxilary Posted April 12, 2003 Share Posted April 12, 2003 OK, here's my dumb idea for making a sump in a 240z tank without having to weld one on the bottom and risk exposing it to damage. Would this work: take a stock tank, boil it out, and split the halves, since it's press seamed together. The tank has 2 baffles in it, if memory serves, and for the lower half, drill some large holes in the baffles. Secure some of that summitt racing fuel foam so fuel doesn't slosh around much, and then weld a sheet of metal with several holes drilled out (we're talking about 1" diameter holes) over the baffles. Now hte lower 1/3 of the tank is one giant sump, that'll prevent fuel from sloshing around and causing starvation. Seal the deal by reassembling the tank and welding the upper and lower halves back together. Only thing left to do would be to put several fittings underneath, and replumb some of the vent lines. dumb, or not? what are the downsides that I may have missed?

Tim240z Posted July 29, 2003 Share Posted July 29, 2003 Alex, If you are planning to split the tank, then why not weld in a reservoir inside the tanks with baffles and one way trap doors with the pickup inside the 'box'. That should work very well.. Tim Quote Link to comment Share on other sites More sharing options...
jeromio Posted July 29, 2003 Share Posted July 29, 2003 I agree, if you're gonna open up the tank, then just make the sump inside the tank. The way the camaro tank works is the pump lives inside a big coffee can sized plastic tank. There's a syphone at the bottom (with a sort of filter bag) that lets fuel in (and out too I suppose). The pump draws fuel from the inside the coffee can which pretty much stays full of fuel. I've removed mine when the tank was 1/4 full and that coffee can, which reaches almost all the way up to the top of the tank, is completely full. I think something like that would be the simplest and easiest. No need to even open up the whole tank. Just make a 4 or so inch hole in the top of the tank, buy or make an appropriately sized can that will fit in the access hole. Put a hole in the can (maybe block it off with some mesh), mount the pump in the can, mount the can to the access hole cover. Quote Link to comment Share on other sites More sharing options...
auxilary Posted August 9, 2003 Author Share Posted August 9, 2003 haha that was a really old post before i learned about sumping and such, ignore it i was just being stupid. I reexamined the tank, and it wasn't worth it. Maybe I'll do it for sh-ts and giggles, and entertain the can/sump/surge idea I have a spare one to mess around with Quote Link to comment Share on other sites More sharing options...
