Seafoam in gas tank DONT DO IT!
Guys dont do it! Works great in the manifold however a really bad idea in the tank. After i did it i had a huge problem with under 1/2 tank of gas. Turns out the seafoam broke all the slidge loose in the tank and cloged the pickup screen on the pump so bad it could not suck any fuel through it. Had to drop the tank and clean the screen out. After having this happen to me i started looking around on the forum. Seems that in the last week about 3 other people have posted with problems after seafoam and under 1/2 tank of gas. Avoid the problem before it becomes one. Dont use it in your gas tank.
SeaFoam is a make or break... Blew a head gasket on a 98 Chevy Venture, and I still stand by it. If there are any weak points, itll find em. Good to know about the Jeep issue though. I put some in at about 193,000 and had no issues, but I didnt put very much. How much did you put in? Is there a pissiblity that it could partially clog the screen? - Im thinking I need to check my fuel pressure LOL
I used 1/2 bottle in the manifold. Worked great. Used the other 1/2 in a full tank of gas. Thats when my problems started. My fuel pressure was fine at idle. Just about 50 lbs. Droped to 30 lbs under load. And what was powerbraking it on a lift. Tires were not even on the ground so yes they did spin. With out a doubt check your pickup. My jeep runs so much better now. Can actually get out of it's own way.
Wow I would have never thought that at all.. But I've never heard of sludge in a gas tank.. The only thing that might build up over a LONG time is dirty gas or water.... This is new to me though.. Thanks for the advice..
The reason you have sludge in the tank is because you have had gas that sat in the tank for a long time and turned into sludge at the bottom.Warning everybody is fine but only a small percentage of people will experience your problem.
Chris, I agree with virm. Seafoam is okay in the fuel tank you may just have had more sludge than most, take it from a guy who uses way too much Seafoam in every car he's ever gotten his hands on including friend's cars.
Hey Ryan whats up! How are those tires holding out for you? Hope all is well. Anyway, I duno i have seen a bunch of guys on here with the same problem as mine. You guys can of course do what you wana do. Im just stating the problems i had due to it. Some with agree some wont. Either way ill use it in an intake manifold again but never in a fuel tank.
I guess the Seafoam did its job then. I've used Seafoam in my tank and went through flawlessly.

Yea i got the pix. Where did you go wheeling LIE 71? Yea droping the tank wasnt a bad thing just wasn't what i wanted to do lol. Really not a bad job at all but 1 more thing taking time away from the lift! Should get started on that soon. Know anyone selling a set of 31"s local?
I have used Sea Foam countless times with no problems whatsoever. It sounds like your screen was on its way to become clogged anyway and the sea foam just helped it along. You cant whine about a product when it is doing its job.
