Magnet on a gas tank??

Lets say you have an old car with a rust problem in the gas tank. Has anyone ever tried to put a magnet on the bottom of the tank, to hopefully hold the rust particles out of suspension, and out of the filters?

Would you think that it may be a hazard of any kind?

 

should work, maybe put them on the rear corners

 

I've used this product before for gastank rust problems.

http://www.kreemproducts.net/

It's originally made for motorcyle tanks, but works just as good on cars.

 

I've used magnets out of discarded large speakers. Figure they're big enough to hold the rust in place.

 

iused a magnet about the size of a half dollar and an ich thick-it was a poerful sucker, no problems.

 

i put a magnet on my gas tank and the car only wanted to run north and south.

 

that's why you gotta use the speaker magnet, they're round so you can go any direction

Kreem sucks. Really. had lotsa problems with it in the past.

POR15 makes a much better product.

 

If you want powerful cheap magnets, grab a junked hard drive from a computer. the curved magnets in those are strong as hell! do NOT get pinched between them- they'll give you a blood blister in an instant.

 

When it comes to gas tank sealers..two words.. red-kote, made by Damon products, I get it through my local radiator shop...Dave BTW, that north south comment was priceless hotrod-Linkin, took me a second or two to quit laughin'

 

He's been hearing that crap ever since he was at UCLA. He's out there busting his buns every night. You try to drag Walton and Lanier up and down the court for 48 minutes.

 

lol..i was wondering when this connection was going to get made

I used that Kreem shit once for a Harley tank....big mistake..always having to clean out my filter and carb of goo..

I have this issue with my 53's tank..might give the ol' speaker magnet a shit before i ditch the tank

 

I'd always thought that rust was NOT magnetic. Iron is, but pure rust isn't. I do know that I had a rusty gas tank and tried a 200-lb rated magnet on the tank, I cleaned the fuel filter once/month and the magnet never made a difference.

 

Haa haa,good one Muttley.

Microwaves have two nice round powerful magnets inside them.Beware and be mindful of the large capacitor as it'll knock the farad-loving gnorts out of you!
They're flatter than speaker magnets but about the same diameter.
(and round,so you can drive to all four points of the compass?)

 

HOTROD...it's been done for years, i know atleast from the mid 50s. also we put magnets on bottom of oil pans, keeps metal out of oil pump. have you ever heard the saying, whats new is old?...POP.

 

I think it would be better to clean the tank out the right way. many times it it more than rust in there screwing things up.

 

I had the same problem!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

just some science shit i found..the magnet on the fuel tank might be a waste of time?


Question: We rusted some steel wool with bleach and vinegar as
catalyst. We removed the wool and drained the liquid through a coffee filter. We
tested the dried residue, which was no longer magnetic. We then heated it in a
spoon over a candle flame, which turned it black. It was magnetic
again. What was the process that "remagnetized" it?
---------------------------------------
Probably what you did is drive off some of the oxygen from the rust
(hematite or goethite) turning it into magnetite, which is black and
magnetic. The balanced chemical reaction starting with goethite would
be:

12 FeO(OH) --> 4 Fe3O4 + 6 H2O + O2

That is the most realistic, since rust is generally hydrated. The
reaction is a little easier to balance from hematite:

6 Fe2O3 --> 4 Fe3O4 + O2

====================================================================
Some oxides of iron are non-magnetic, others are magnetic.
Fe2O3 . nH2O (red rust) is definitely non-magnetic.
"Magnetite" mineral is an iron oxide about like hematite,
something like Fe2O3 . FeO. (aka Fe3O4)
FeO is blackish not red, and the mixes tend to be gray-black too.

Your residue lost all water and a little oxygen
and maybe also recrystallized while in the solid state,
to a form more appropriate to its new composition. .
Check out whether your estimated peak temperature, in degrees K,
was more than 1/3 to 1/2 of the melting point of Fe3O4, also in degK.
If so some recrystallization should be able to occur on the molecular
level, though perhaps not to crystals large enough to be visible.

It is possible the gasses in the candle flame helped chemically,
not just thermally, with some of the oxygen removal.
If the flame wrapped around the spoon on all sides,
it might create an oxygen-depleted or reducing atmosphere in the spoon.
Carbon monoxide, unburned wax fumes, and soot are all reducing agents
for the conversion of Fe2O3 to Fe3O4.

 

Ferrous oxide (rust) is magnetic, in fact, it's the part of magnetic recording tape that makes the tape hold sound/data. I'm with 49ratfink, if you know you got rust then do what you need to do to eliminate the cause of the problem rather than trying to come up with a magnetic rust collection device... sooner or later the tank will rust through.

 

:d

Pull the tank and clean it well. Use red-kote to seal against future rust.

 

I always heard that a magnet would speed up the rusting process...

 

i too, find that kreem is delicate, and tought to get to work in a cars tank.

for mini bikes and stuff like that, it works ok, if you install it right.

biggest mistake is letting the m.e.k. dry before pouring in the kreem.

anyway, as said, there are better coatings for a car's tank.

worth noting, once you coat them, most radiator shops wont touch them, so get it right the first time

I routinely put magnets inside of gas tanks I use a stainless steel hose clamp to attach a copper wire so I can retrieve it and clean off the rust. Also use a settlement bowl with a creamic filter between the gas tank and the fuel pump. Even by taking off a gas tank you cannott get to all of the area to clean it completly. OldWolf

 

Now what in the world would you want to stick to a cow with a magnet?

Best thing to use is a couple of magnets out of an old computer hard drive. Nice strong magnetic field!!

 

My vote goes to red-kote it works great.Just done use it inside the shop, It will Make you feel really good(like a kite) haha

 

I second that.

 

Just cause you don't know how to properly use KREEM, doesn't make it a bad product!!! I've used it for years, in cars, trucks and bikes and NEVER had a problem.
