ECS-Fuel System Problem ???
So today I started cutting the tank for the ECS fuel system. After cutting, I went to mount the sump in the tank. Well after I was done I filled the tank back up with some fuel and noticed that it was leaking at the seal...has anyone else run into this problem before? What can I do to fix this problem? All screws are tight and it looks like it is sealed good.

Mines in for 2 years now and not a problem, did you pinch the seal? The only problem a very select few have had was with cavitation which is just a matter of relocating the pump by the rear wheel well on the drivers side.
Post this in the forced induction forum as many others will chime in as a lot of us are running their system and post in that venue.

If the hole was cut to the currect size, I would think you have a bad seal...........Have you try to call Doug.
Also, make sure that the aluminum piece that goes on the tank isperfectly flat.

I haven't tried to call ECS...I'll called several time for some install instruction and also e-mail and PMed them several times and nothing I still don't have install instructions...I'm installing this system from instructions that CF forum member MIKE04, gave me.

I had a small leak on mine the first time I added gas. I loosed the screws and then snugged them back down. That took care of it for me. You could have the O ring seal out of the grove, you would have to pull the bracket back appart to check.
Getting those screws tightened down is not that easy if you still have the rear cross member on the car like I did. I used a short screw driver with a wrench on the grip for extra twisting power. If you tightened them down with just your grip on the screw driver you might want to try the wrench trick to get another 1/2 turn or so. Just don't strip the treads out in the backing plate.
Good luck!

I had a problem with my FFS/ECS setup too, similar to yours. It turns out the tank itself was warped a bit on the inside which made it tough to get a good seal.
To fix it I basically put a thick coat of Permatex oil/gas compatible sealant around the perimeter of the inner plate (which was tricky!) Let it dry for 24 hours just to be sure, then filled it back up with gas and all was well.

so i came to the conclusion today that the crappy o-ring gasket isn't enought for sealing. so i decided to go buy a 12" x 12" x 1/8" thick sheet of silicone rubber and cut it in the shape that is needed to seal the tank. the only problem i'm having now is finding a place to buy that material for making it...anyone know where i can purchase this without having to buy a whole yard or roll of it for something so little. i'm also swaping out the cheap philps screw heads with hardened allen key head bolds. with that i will be able to screew it together tightly and not have to worry about stripping the heads of the bolts. i'll be keeping everyone posted on my progress.
