Has anyone ever used a surge tank for an efi swap? Anyone have any experience or ideas? It seems like it would be cheaper than an efi tank. Here are a few links explaining and giving examples.

they are an excellent idea, and virtually eliminate any fuel slosh issues. They do require two pumps, additional plumbing, and a surge tank of some sort, but they work awesome.

Interesting idea, should work ok in low HP application.
A higher HP pump would probably run into overheating the fuel during low demand (idle and cruise), and might empty that tank at WOT in matter of seconds.

Would it support an LS2? Would there be a way to regulate the voltage to the smaller pump in order to keep the surge tank full at WOT, and not flow as much during cruising and idle speeds.

Ya probably, but it's getting to complicated.
Just run a one good EFI pump (like an aeromotive A-1000) in or near the tank, and a good regulator with a return line to the tank.

Absolutely not, it will work with virtually any HP motor.

and be stuck on the side of the road on Power Tour like a dozen other guys. It's all about regulator placement, heating the bypassed fuel, and running a big pump at full voltage for long periods of time. And the voltage reducers seem to help but screw with the pump amps and cause low life span for the pump.

Ideally regulate before the engine and bypass the fuel as far away from the exhaust and other heat sources as possible. Also, a fuel pump controller that pulses the fuel pump instead of cutting the voltage is the way to go.

ok, my thinking was heading towards using a walbro 255 in line pump with an aeromotive regulator. Possibly mounting the surge tank with the pump and regulator in the rear near the gas tank. I was planning on the surge tank being about a 1/2 to 1 gallon tank. I am not sure what size pump to use to fill the surge tank. I like the idea of the fuel pump speed controller I would prefer not to use one but will if I have to.
