Surge Tank?

[Boosted98gsx]

Has anyone ever fabbed up a surge tank for us 2g-ers who are stuck with this crap saddle tank and cannot feed more than a walbro 255 to the rail w/o serious hacking?

So, rather than having to drop the entire fuel tank and build a cell, would going with a fuel surge tank be a viable method to get fuel to the rail? I was thinking this; feed with a walbro 255, mount in the engine bay and drain by an Aeromotive Eliminator, with -10an to the rail then regulated by the black top red bottom Aeromotive reg, and returned to the surge tank. Overflow returning to the OEM return line back to the saddle tank, so I would never have to worry about overwhelming the OEM return line to the tank, all the high volume stuff is just handled by the surge tank.

I stumbled on this site: Tech Page

and it seems easy enough to rig up, but where should I mount it? Under the hood? Fuel filter before the tank, or after (thinking after), and how likely would it be to drain the thing during a run with a GT35R, thus to what capacity should it be made, and out of what material?


Thanks

A guy here in town that i autocross with has one and he can actually take right hand turns wide open. The tank is kinda small so on big sweepers it still gets bad if he's low on gas, but he can autocross on a 1/4 tank!! I think his hold just under 1/2 gallon

Plumbing sounds right. A small Junior Dragster fuel cell would work nicely and they're built for small spaces and to handle fuel safely. I'd mount it under the hood so you can use the stock lines up to the engine bay and back, and keep the runs of expensive 10an line short I guess. Many JD fuel cells are "vertical," tall and thin, so they'll be easy to stick in a corner of the engine bay.
