i have cleaned out the gas tank before i put my walboro in and then again after that and now its acting like it did before (like the pump sock filter is clogging up).

i heard there was a tablet that dissolves everything in it and cleans the side and crap.

Replace your fuel filter. Never hurts

Ah, the old "mechanic in a bottle" dream.

I don't think there's any substitute for getting it hot tanked and resealed...especially since you've tried twice yourself and failed.

first find what is the cause of the dirt into the tank. If there are rust inside the tank you need to take it out and buy a Por15 Tank Sealer and follow the instrucctions (I think that there is a Eastwood brand product to seal and encapsulate the tank to stop rust, check for the Eastwood website, they have a lot of stuff for bodywork).

I've got the solution - as long as your tank isn't rusting. :P

My wife and I had bought a BMW that had been sitting for years. Wouldn't start, troubleshooting found no fuel to the engine. Changed the fuel pump and it started like a dream, drove it around the block, parked it and it never started again. Pulled the fuelpump and found (no lie) about a 1/2" of varnished gas under the new stuff.

I'd heard of businesses that would steam clean and seal the tank for $60. So I called around and the cheapest I heard (bringing the tank to them, not on the car!) was $225, or buy a replacement tank for $400.

I dropped the tank, and had a gallon of liquid parts/carb cleaner that I'd picked up at the parts store for $10. I drained all the fuel and poured the whole gallon in. I got a spare toilet brush and every couple of hours would poke it through the hole and scrub for a minute or so, then I'd lift one end of the tank and let it all run to the other side, then do it again from the other side, then do it back for a minute to make sure the varnish all stayed under the cleaner. After 3 days I emptied it all out, dumped about a quart of purple degreaser into it and ran water through the tank until it came out clear. (Read a LOT of water). Then I added a lot of regular 99c squirt bottle dish soap, and ran water from the hose into it until the suds stopped coming, then emptied the water.

I had figured that it would work, but when I looked in afterwards the bottom had a mirror finish on it, with no varnish whatsoever. And for $15 instead of $225. If you had a rust problem, this is where you'd probably put in the tank sealer, but there wasn't any noticeable rust on her '88 fuel tank. (Because realistically, how much water really sees the inside of your gas tank?)

For $15, it's worth a try.

I always use dawn dish soap, just plain old dawn, no fancy flavors no generic brands. Buy a big thing of it and a few gallons of boiling water. you do the hokey pokey and you spin your self around.. Vala! Or...if you have a pressure washer hook it up to the output on your hot water heater and use just high pressured hot water.. There are many different ways to skin a cat.

But Richter's way seems more profound. Defiantly more thorough

Yep, after I went through all that, I wondered if dishsoap alone wouldn't cut down the varnish just fine. Try it first, dishsoap is cheap, and you won't even use a whole bottle anyway.

Drop the tank.

Put about a gallon or two of kerosene or parts cleaner into the tank.

Put a few lengths of assorted chain into the tank.

Seal the openings however you can to get the minimum amount of leakage.

Have a ball rolling the tank around your yard for a while (hence don't want to many leaks, unless you hate your grass or something)

Drain tank along with all the nasty sludge and chunked up crapola that got worked loose.

Finish off with a heavy nylon brush (preferebly solvent resistant)

Rinse, dry. Repeat if necessary.

Always works for me. Makes it all nice and shiny inside.

well i guess i better pull the pump to make sure that its getting clogged again or not.(the screws are a bitch to undo) but a guy on the rtek forum said try a fpr is its not clogging up? we will see

As long as they're not dumbasses coating a baffled tank, which means your car will starve in hard left corners.
