Default Cool surge tank ideas!

Got curious about surge tanks, after hearing about fuel starvation issues on the WRX. Check out these two pages, both have really cool information about creating home-made surge tank setups.

http://www.teglerizer.com/fi/fi_fuelsystem.htm

http://www.geocities.com/hrayhouston/antisurgetank.html

The second is a really cool idea! The only problems I can think of is 1) feeding with the in-tank, high-pressure pump, and 2) the o-ring on the filter getting ruined by fuel. Of course, you could just silicone it and be good...

I like cheap stuff:-)

The first one looks ok...second one is just ghetto. I wouldn't mess around with fuel, you want a metal sealed container. My surge tank was custom made for me in aluminum and it was not very expensive at all. The pump, hoses, and fittings were way more expensive than the tank itself.

you've got a point... plastic is easily cracked. A fuel leak that far away from the engine poses minimal danger, though. Unless you're considering danger to the engine; that's a different story, one that only ends badly.

If you ask me, even minimal danger is too much. Especially when you can spend another $50-100 and have something much safer. Even if it's away from the engine you don't want fuel leaking in the car. You never know what will cause it to ignite.

Surgetanks arent all that expensive and relatively cheap in scheme of things.
