Gas Tanks

Figerglass Gas Tanks

Editor - 06/26

A problems that showed up a few years ago is repo fiberglass tanks that look like the steel ones, seemed like a promising solution. Not sure how many were sold, but when the petro industry switched to ethnol doped gas and other additives, the gas desolved the coating and the fibergalss that then went into the engine. If you were lucky it only messed up the carb but some complete engines were runied. If you run accross a fibergalss reproduction don't use it, better yet destroy it.

Cleaning a Tank

Jim_Bollman - 11/10/00

A friend cleaned out a Crosley gas tank by putting few hand fulls of crushed stone in the tank and tied it in a cement fixer. He then ran the mixer till the stones and beat all the rust out. Then after rinsing well, I think he used a coating compound inside. Jim...

I take my tanks (IF solid) to the sandblaster--he clamps a rubber hose on the end-inserts in tank-hose flops around & cleans inside--he blasts outside also. Super Job

The problem with cleaning a gas tank by sandblasting or rolling gravel around inside is getting all the crud out afterwards. Sand in the gas tank is a definite no-no. I think you're safer having the tank boiled out at a radiator shop. I believe Eastwood sells a 1-part coating for the inside of the tank.

Jim_Bollman - 11/12/00

I agree getting all the dirt out after sandblasting or rolling gravel is tough but after you get it as clean as you can, putting in the tank coating stuff will embed all that remains in the rubber coating so it shouldn't be a problem.

Word of caution: My experience when I tried to some coatings in large volume tanks it would harden before coating the entire tank and it is so thick you can't slosh it around. Ended up thinning 1 to 1 with keytone and was tolerable. If had to do again I would thin 2:1 or more. Had some stuff [I think from Hirch] 30 years ago that was the consistency of milk, worked great! Don't know if present day Hirch is as good.

Just a note to say if you get a tank that is to bad some radiator shops has a sealer that coats the inside and outside of the tank, the inside is a red color the outside black looks good lifetime warranty.

I have cleaned tanks before with pea sized stones from garden shop about 5 lbs. add some Ajax cleanser and water and shake for a long time replacing water and cleanser occasionally, shake all out and rinse with water till clean, I use a hair dryer to dry out and then make covers for all holes and dump in a quart of tank liner seal it up and turn all over to coat all of inside, open and pour out excess back in can,tomorrow pour tank liner back in and recoat again and drain,when dry you have a tank that will last as long as you live and never rust again. I get tank liner from Little Dearborn Ford Parts.

Most common thing that plugs a gas tank is ....RUST! The only way to fix is to remove the tank and have it cleaned or clean yourself. Then replace tank and put a inline filter on and change regularly for awhile. There are many postings on gas tank cleaning. Dalef62

Here's a similar story. In 1985 I was invited to ride in the Wadsworth, Illinois parade aboard the Newport Township FD Crosley. There is a steep hill upward off the main street and the Crosley climbed it, and then died. The crew couldn't restart it. They then prepared to attach a chain to tow it through the parade. But how would that look? Thinking about that steep hill, I had a hunch that the tank outlet had plugged with silt while the Crosley climbed it. I told my hunch to the crew. Quickly they disconnected the fuel line at the pump and blew through ... hard! Reconnecting, we primed the carburetor, and it fired. The Crosley rolled proudly under its own power that beautiful September day. With me aboard.

'47 CC Gas Tank Location

cosmicray48236 - 11/27/01

I purchased a gas tank and am now trying to install it. As shipped to me, it will hit the filler plug on the differential housing. Has anyone had this problem and if so, how did you fix it?

cosmicray48236 - 11/28/01

Apparently someone along the way relocated the gas tank in this car so I don't know exactly where it belongs. Can anyone tell me the distance between the cross member and the tank. With that info I will be able to make new brackets and put it where it belongs.

hitekwarehouse - 11/29/01

I have a 48 cc Convertible I am restoring, right now the cross member is not in, however from the lip that holds the stone shield to the rear of the tank mount bracket is 16 1/2". The bracket is the one that you slide square head bolts in, and it is 10 3/4" long. I just mounted the tank, and the differential left side is the closest to the tank, less than one inch. The filler plug sets a bit lower than the tank.

Gas Tank Sealer

It looks like a product you can get at a motorcycles shop should work.

Gas Tank Fills Slow and Blows Back and the Gas Gauge Bounces

Tank Fills Slow

Crosley gas tanks not filling at a reasonable rate, with out the gas gushing back out was reported by several members and we certainly don't want to waste any gas these days.  There was a long discussion with as many having the problem as offering solutions.  Here are a few of the solutions that were offered.  I edited the material to save space and minimizing the repeat information.

Blown air through vent pipe to be sure it is not clogged. Remove the tank and add gas-line to the vent pipe to raise the end closer to the top of the tank.  Check for small crack in the vent pipe where the vent pipe is fixed to the filler tube.

Chuckhk - 

Check if vent tube is bent down in the tank, should be bent towards the top of the tank.  Most vents get bent when the neck is removed, or straighten so they go in easier. Make sure the vent tube isn't bent part way shut.

JimBollman - 

If you got a hole or a split in the part of the vent tube going down the filler pipe.  This could have been from it being stressed from bumping the part that sticks out in the tank when installing.  The air coming up the vent would suck some gas in to the vent as it went by during filling.  This could explain why extending the vent didn't help. Try plugging one end and blowing threw the vent to see if it is air tight?

Ealimke - 

Replace the vent tub. Mine had a small hole on the under side and it would fill up with gas and then it does not vent.

Garyellis1056 -

I recently had the same experience.  I worked the problem for a year and removed the gas tank three times. The problem probably is the vent tube inside the filler tube.  The vent tube is brazed to the base of the filler tube where it exits and where the piece of hose connects it to the gas tank .  The vent then continues on into the gas tank slopping upward.  In my case, the vent tube was cracked where is was brazed at the end of the filler tube, (it had been brazed before.  Must be a weak point) which allowed gas to enter the vent.  I removed the filler tube, dropped the tank and had a machine shop close the crack and re-braze the vent,  I carefully reinserted the vent into the tank.  It corrected the problem.

A50CrosleyTrk - 

My Dad run the vent tube from the top of the tank, outside of the  filler tube, though the frame, back to the filler tube inside the  wagon, and kept it as high with no swags as possible.  A dip in the  pipe could collect gasoline and cause the air block.

IsettaJoe - 

I may have to drop the tank. How much of a job is it? Any "surprises" to be aware of? When the vent tube goes into the tank, I assume it needs to be above the gas line. As long as it looks like I am going to need to drop the tank on my 52 wagon, does anyone have advice on what to look for that is causing my gas gauge to bounce wildly all the time from 1/4 to 3/4 full?

Berard - 

You will need to get the vent to the very highest point possible. Once the fuel reaches this point and covers the inside end of the vent you have lost all venting. On my 51 SS I have removed the tank in December and it's a piece of cake providing you have no rust to deal with. On mine it involves 4 nuts and the pipe to the front of the car, lower it enough to get to disconnect the fuel gage sender wires, and the filler pipe follows the whole mess out.

Ealimke - 

I had the same gas gauge problem, I dropped the tank and looked inside and the baffle had broken loose and let the gas slouch back and forth.

Plugged Gas Tank Pickup Tube

super52sport – 6/16/05

After sitting in storage for 27 years with some gas in the tank the pickup tube in the gas tank on my '52 Supersport is plugged up. I've tried blowing trough it and pushing a wire through it. I can't find a wire that is strong enough to push through the blockage but flexible enough to go around the corner. I'm sure I'm not the first one to have this problem. Anyone have a solution? The tank is out of the car.

If noone has a better idea I'm going to try to make a "snake" out of a piece of speedometer cable turned by an electric drill.

BTW, it started right up after I filed the points and poured a little gas in the carb. I had to disconnect the water pump becasue it won't turn.

chuckhk – 6/16/05

Yep speedometer cable.

hotshotcrosley – 6/17/05

Had the same problem on a Hot Shot and used a cutoff speedo cable on a drill and it fixed the problem.

super52sport – 6/17/05

Thanks. It worked. It wasn't easy and I had to flatten out the end to make it cut.
