PVC and Gasoline - Compatible?

[Tonka J200]

Trying to replace the filler hose that connects to the tank in my '63. OBVIOUSLY a replacement is not to be found. I bought a correct size chunk of straight filler hose, but it won't make the 45 degree bend without kinking. I found a perfect size PVC 45 elbow that would work just fine, but will the PVC stand up to the gasoline? Or should I just go to a muffler shop and have them bend a small piece of steel pipe and connect it at each end with chunks of the rubber fuel filler hose?

I don't know for sure, but I would guess that gasoline will eat through PVC over time. I would suggest haveing a muffler shop bend you a new filler pipe. You could always use some mandrel bends where needed and have them welded to the straight section of the pipe.

Dude...IT'S GAS! Spend the ten bucks to get metal pipe and sleep better at night. I'm all for saving money - but that doesn't sound like an economical decision... :D

i made 2 filler necks out of sch 80 pvc for a cj and the step van both in 1992 both are still sorking fine no leaks or cracks i say go for it

Both types of PVC (40 and 80) are supposed to be resistant to petroleum products.

Having said that, most glues are not.......

gsmikie what glue did you use?

[Sitting Bull]

Not trying to be a smart-azz here...but we're talking one elbow right? PVC, $5, should work. Metal, $10, WILL work.

Not doubting the auto-tranny-god (whens that video coming out anyway), but when dealing with volitile liquids, I'd be erroring on the safe side - especially if it was only a 5 dollar difference.

i went out and looked i used the blue glue

Anyone know what the following items are made of? Plastic Gas Can, Plastic Fuel Filter, Plastic Gas Tank, Plastic Floats. tongue.gif tongue.gif LOL PVC works fine for gas. Actually some Wags had plastic filler necks, 76 I think it was, better than the steel tube ones, no rust or condesation. ;)

LMAO!!! I hate you Pete. (good call, I'll shut up now)

ok pete what are you trying to say ......i dont get it !!!!!!!

There are many different types of plastic. If gas is harmful to the plastic, I wouldn't worry so much about a leak, what I would worry about is what is comming off of the plastic and heading towards the engine. In many locations, you cannot use PVC for plumbing below ground level (such as a basement). Don't know why, but it would make me think twice about it. PVC is cheap, but if a substance were that cheap and was suitable, why wouldn't we see it being used in new cars??

[gsmikie]

we run it all around the shop and hook it up to the air compressor (outlet every 10 feet ) 180 psi for compressed air but keep it out of the sun

[Chero77]

I think plastic gas tanks are made from polyethelene, which apparently leaks gas fumes to some small degree. CARB won't allow manufacturers PZEVS (partial zero emission vehicles) to use it. CARB makes them use steel tanks. I don't know whether PVC would work for a filler tube, but I wouldn't put it on my Jeep. Pepboys has 45 and 90 degree mandrel bends for just a few dollars. Why bother with PVC.

sorry what did i miss i was outside building my new winch bumper and roll bar outa pvc it looks cool and since im in the desert i put a faucet in the roll bar so that if i get thursty i can turn it on and get a drink of water.........

The off the shelf 45 and 90 degree radius metal exhaust elbows have too large a radius and won't fit. I'd have to have one custom bent (if it could be bent tight enough). The PVC elbow is almost a zero radius at the inside and would work perfectly. I would use two 6" pieces of the rubber filler pipe I bought with the small PVC elbow in the middle and it would fit like a dream.

Take a peice of pvc and soak it in gas. If you are not using a glued section of pvc, don't worry about the pvc if it passes the soak test without breaking down.

Good luck

... About three years ago I made a gasoline filler neck out of the White PVC pipe fittings and glued it all together with J-B Weld. I also soaked a piece of the PVC in gasoline for about four months and didn't find any problems.

Have a good one http://www.michiganjeepers.com/forums/images/graemlins/popcorn.gif and CUL.. Don S..

[timmirvin]

It will pass any "soak" test we could come up with.....

I reccommend using the SCH 80. Thicker walls. Better color.

GSMikie thanx for all the laughter you have given me lately!!!!!!! smile.gif :D

[gsmikie]

im back i was outside building a new garage out of pvc and parachute (12 car) what did miss ???? tomorrow im going to build a full size pool and a upstairs with pvc........need more hack saw blades

[Thunder Struck]

You know what gas really likes Styrofoam. Just keep feeding it and it gets real thick and....ohhh haha aaahhh nevermind smile.gif

[jeepguzzi]

Here is something you all may not have thought of. GSmikie might know, since his whole garage and shop are PVC.

Don't you have a static electricity problem with it?? I know that the hair on my arms will stand up whenever I am handling it. Would you REALLY want that as a filler tube??

I am thinking of getting a welder for Christmas. Which models have PVC capability?

[gsmikie]

hot glue auto feeder the static electricity is from pvc rubbing aganist a conductive source
