Newton Posted January 26, 2017 Share Posted January 26, 2017 so when i bought my truck the PO had just put in a new fuel well atleast thats what he said and to be honest it had looked kinda new on the outside until my fuel pump went bad and i took it down..the inside of the tank was well rusted ..through some rust remover in there cleaned it up nicely put in new pump..that was about 4 months ago..took the tank down thiis week to remove the bed pulled out the fuel pump and was already rusted I'm guessing the inside of the tank as well... is the a reason y the tank is rusting so quickly i don't think water is getting in there or maybe its he quality of gas here or maybe moisture inside the tank is it a problem or is that normal..can it be prevented do i need to get a new tank ..whats the deal here?

Hippie66 Posted January 26, 2017 Share Posted January 26, 2017 Doesn't sound like the tank was new if it's that bad. I replaced my 18 gallon tank with one from Amazon. Appears to be exactly the same as the original. Summit has the grommet for the roll over valves on top of the tank at a good price. If you were close to Oklahoma, I'd offer you my old tank. It wasn't as bad as I expected. Link to comment Share on other sites More sharing options...
gogmorgo Posted January 26, 2017 Share Posted January 26, 2017 What fuel are you buying and how often? Mostly just curious. Can't hurt to toss some water remover/ gas-line antifreeze in there. My tank is rusted pretty badly on the outside, to the point I'm almost concerned about it. But I pulled the sender this summer to replace the fuel pump and everything in there was minty and brand-new looking, even though I have no issues believing it all to be original, 300,000 miles later, based on what I see out side. Only difference between all the nasty ones I see you guys posting that I can think of is six months of winter fuel up here in Canada. Link to comment Share on other sites More sharing options...

Well even though the tank might not have been new but the fact that it started rusting not too long after I cleaned out the rust is what concerns me...

johnj92131 Posted January 27, 2017 Share Posted January 27, 2017 Just don't skip anything on preparing the tank prior to coating it. Preparation is 99% of a really good paint/coating job. An old time trick with rusty gas tanks is to put heavy chain in the tank, then slosh the chain all around in the tank to knock off as much rust as possible. Do it a couple of times for a really good cleaning. Link to comment Share on other sites More sharing options...
