Fuel Tank from Hell!!!

[MuddyMaestro]

Ok, I have a '73 FJ40 with original gas tank and fuel lines. Recently, my fuel lines and filters have been clogging up with trash (mostly rust) and it get's really annoying when you're out with the guys tearing the rocks up and suddenly you can't go anywhere without someone towing you...

My question is, what can I do, besides buying a new tank, to fix my problem for at least enough time for me to get the money for another tank? My dad and I rinsed the tank out with both water and kerosene, but that only seemed to work for about 100 miles. Any ideas?

take it to a car wash and pressure wash it. and take rocks put them in there and shake it around to losen rust. then pressure wash out.

you can get some tank sealers to put in there POR15 makes one. never used it.

bottom line is buy a new one... make sure to get an OEM one

Muddy,

Use the search function and try "rusty gas tank". I saw a lot of replies on solutions from NAPA, etc. I have also heard of folks taking their tanks to a radiator shop, having them washed out, and using a solution that coats the interior. I went through this with my 70 Ford P/U which has a tank behind the seat. I washed and washed and put in a little diesel and washed....etc. Don't forget to change out your fuel filters. I'm sure you will hear more detailed responses shortly.

You may end up with carb issues also. Most filters are just rock catchers (don't skimp here). I wonder how much of the "fines" have made it past them.

I broke down and bought a Racor which filters down to 5 microns.

I have the same problem, I put two fuel filters in-line. It has helped me get by until I figure out a longer solution.

I also put two NAPA filters inline.

two inline filters is the way to go!! Bottmline is get a new tank....

I would think taking it to a radiator shop and getting it flushed would work, but you are still left with a old tank.

x2 on useing two inline filters. i did this for a couple years . had pretty good results with one of those glass filters first them a good paper type filter after that. the glass ones are good for the larger stuff and you can clean them out on the trail.

tank work

I recently had my tank dipped in a chemical bath and professionally cleaned. I believe it was a chemical bath as i was not actually there to watch. it may have been a super hot bath of some type but after that the company coated the bottom and the tank is as new!

it was 140 bucks and have had ZERO issues. take it to a classic car restoration company and they will most likely have experience with older, rusty tanks. most classic car guys want the orig tanks and that's how they do it. if it's terrible they'll have to open it up, that's when it get expensive!!

your choice! good luck and duel filter that hoe! im mean hose

i used the por15 kit years ago and it worked great. clean the tank out or have it done, i used muriatic acid and water mix to clean the tank. then neutralized the acid with baking soda and rinse thoroughly and seal with por15 tank kit. filters only last so long and will continue to clog and so will your pic up tube in the tank.

do the search because its been beat to death

Buy the polymer one that Jsaltlick has in the forsale section.

another vote for having it boiled out in a hot tank, this will expose alot of thin metal or rust holes that you don't think are there by normal inspection, after the boil out, if it looks to be a sound tank you can have the radiator shop or yourself coat the interior with a liquid liner. The one the shop here used was red, took awhile to cure, like days, and worked excellent. FWIW I used it on an old porsche tank that had rust and carmelized gas in it and it was nice after being reworked.

I already have dual inline filters. what's happening is the s*** is getting clogged in the lines and the filters aren't getting any fuel to filter

What I did for my 73' when the tank was rusty is I washed it with water and threw some chain inside to help break up the scale. Then I got some great sealer and shloshed that in and let it dry. It worked great. I got the sealer at the local avaition parts store. They use the sealer in airplane tanks so you figue it's got to be good. The stuff is not cheap either. I did this years ago and a quart cost me $25. big ones. However you decide to clean it, seal it after. Change your lines too and you should be running with the big boys again in no time. To help dry the stuff I put a drop light with a bell on and just set it on top of the tank to generate some heat to help it dry.

Hi All:

I'd advocate doing it right the first time.

Contact "C-Dan" here on MUD (he works at American Toyota.) He can get you an OE Toyota 40 Series fuel tank for a good price. Install the new tank, flush-out the fuel lines, and be done with it!

I say this after having several gas tank issues over the last 11 years I've owned my FJ40!

Good luck!

Alan

CCOT Tank

My tank on my 74 FJ40 finally rusted through, and I bought a replica from Cool Cruisers for about $220. No problems, and I have a NEW tank with NO rust or other issues. I think they are on sale now.
