Gas tank cleaning for the new year?

« on: December 29, 2008, 04:15:59 PM »
Stupie got a gas tank for Xmas, Well,  I got the tank a year Ago,  and I'm installing it this xmas season.    All your talk about the reliability of JP weld and gas vapors worked.   This is a previously owned gas tank that went in a fuel injected stuperbeetle.   IS it common practic to wash out the tank with water?  Will washing with water make it rust more?  Or should I just vacuum the rust the best I can?.

Gas tank cleaning for the new year?

This is for a bus tank, but the steps are basically the same for any VW tank:  http://www.ratwell.com/technical/FuelTankRestoration.html

Here's a link to the POR-15 kit:  http://www.por15.com/prodinfo.asp?grp=FTRK&dept=12

Rolling a chain around in it to loosen up the rust and sloshing it out with acid (as described in the first part of the article above) will get the tank clean, but if you don't do something to seal it, it'll be back before you can blink.  It seems like a waste to clean and seal an old tank when for just a few dollars more you can get a new one, but if you do it right, you're done.  You'll never have to worry about it again.  If you buy a new tank, you wan't have to worry about it for at least a few months . . . maybe even a year or two, but a new tank, untreated, WILL rust.  And it will probably rust much quicker than your original.   8)

good stuff Zen,    info said ,  Yes to water hosing the the tank.  Then it went on about buying acid and things.   I'm thinking that if I fill it with waste oil that would stop the rust for a while,  Coat the tank with oil.  then fill it with gas.  I would not notice the oil smoke,     SC

SC,
Gas disolves oil and then after the 1st tank you are back to square 1.
At least you would get some "upper cylinder lubricant" in with the gas..
Hey it works for weed wackers, and I am sure that there is a weed wacker part on there some where....

If you get the loose rust out and wash it out with acid, you are almost back to a new tank (yeah, you have to buy the acid, but it's cheap).  Sloshing oil around in it will keep it rusting until you can get gas in it.  After that, you're not protected . . . but it'll take a while for the rust to come back enough to cause a problem.  It beats leaving rust in it any day of the week . . . but coating it would fix the rust once and for all.   8)

Zen,  You shared  all  this great advice,  then I ignore it and just through it in.

I hosed out the tank,  Used a leaf blower to dry it out.  Stuffed back in Stupie

SInce I had all that expensive 4 dollar gas in my wrecked Subaru.  I went out and got some clear hose,    to syphin it out.   What was wierd was that the back hatch was up when I was trying to get the suction going and then it fell down hard on my head.  Jimminy crickets that hurt. WHile typing now,  I reached up there to check the damage.  I'm leaking transmission fluid I think.  Owe.  My Sube is mad at me  

So While I waited for 5 gallons to squezze thru a 1/4 inch hose.  I looked at why the ignitons fuse blows when I signal right turns.  Left turns blink no problems.  I took the light lenses off  and pulled the bulbs for fun.  Poof  fuse gone.  Stick in new fuse,  Put bulbs and lenses back in.   SOmetimes a good knock in the head is what a guy needs to figure out Vw's.  

 I took the steering wheel off and pulled out the signal blinker levers switch thing.  Sweet,  The steering wheel had rubbed thru wires  so I got our my shoe box of duct tape,  After deciding that the white duct tape is best for blinker wires,  I taped it,  Yahoo.  Blinkers on bothe sides,

Back to the new gas tank,  Poured in new gas,  Found out I did not tighten all the hose well,  gas all in the spare tire well.  
Stupie no start,  I'm charging the battery.  SC

:lol:  :lol:  :lol:  :lol:  Sorry.  I'm not laughing at you, I'm laughing . . . OK, let's just leave it at I'm laughing.  Hope your head isn't perminantly damaged.  I'm begining to beleive Ret.Bugtech is on to something with his "triangle" theory.  That sounds like something that would happen to me.   :wink:

Gas in the spare tire well . . . charging the battery . . . in the "triangle" . . .  :whistle:  Hope you still have eyebrows when this is over!   :lol:

Or maybe it was the blood offering you gave him?
Happy new year,

Or maybe the "magic" words you uttered when the hatch hit your head?  :oops:

I'm glad you let a Dr. glue up the gash . . . Duct tape would be painful when you went to remove it and JB Weld would dry too hard and let you continue to leak "transmission fluid."

All joking aside, glad you survived and got to hear Stupie fire up again after going to all the trouble of installing a new gas tank!  Hummmm . . . maybe I shouldn't use "fire" and "Stupie" and "gas" in the same sentence . . .

Leaf Blower

« Reply #12 on: June 23, 2009, 12:11:51 AM »
Thanks for the great idea with the blower. I've been soaking my 30 PICT-1 carburetor in cleaning solvent and I need to wash it out with water and blow it out with compressed air. Although not particularly elegant, a leaf blower will do the trick. Unfortunately I don't have a compressor. Maybe someday.
