I just replaced my Nomad tank last month because it was leaking. I thought the top rusted away, so I decided to change it. While I was pulling the sending unit, I found the rubber gasket spllit. I made one out of cork and found the tank was okay. It's a big job since you must slide the rear-end forward on the springs. I put the new tank in and O ring on the filler neck. Now I'm ready to rock and roll.
Great video and explanation of something that bites most tri five newbies. And you make a good point about the copper washers. GM was in the business of making money, not adding extra parts =$ that the car didn't need.
Thanks , not a waste of time. Explained things in a simple manner. I have leaking fuel system when to much fuel is put in.. 57 wagon. I’ll have to look at it.
I am going to be replacing my tank on a 57 Belair, I have a place to buy the cork gasket, and clutch screws but what O ring from H&H did you get? do you have a part # or size?
Good advice I used one of those rubber gaskets years ago and mine didn't leak then but did later. Funny story about o rings. The F-35 has canopy defog ducts that use hot bleed air from the engine and the tubes are sealed with a fitting that uses o rings. We were using plenty of lube on them in assembly. They couldn't figure out what was getting on the inside of the canopy (which is Lexan and they can't use anything that cuts Vaseline to clean it) They traced it back to us lubing the o rings. They finally had a vendor make a special fitting that was pre lubed with something that the hot air didn't blow on the canopy.
Half, 55, 4 door sedan, 265 4 barrel. Is it 3/8 or 5/16? Guys on the tri five forum say the only thing that got 3/8 was fuel injection or 2 / 4 barrel carbs. I just ordered everything new and I ordered 5/16 on the sending unit. Now I am confused.
I believe the original 1955 265 with a two barrel and single four barrel had 5/16. If swapping to any bigger cubic inch engine, 3/8 is a good idea. I usually do 3/8 when I build one but most of my cars had 350's and 400's
I just installed a new fuel tank on my 55 and used old filler tube...also got new gas cap...gas cap appears to be non-vented...but it needs to be vented...should I put the gas cap on it and blow compressed air in the sender line to see if air comes out of the cap?
@@haffrods7055 I just went out to the garage and looked at the top of the filler neck and it has a small v shape in it...maybe this is an area where it breathes through?

Thanks very much!!! If not for your video I would have made all the mistakes you teach us to avoid.
You're welcome Elijah

Thank you for wasting my time you slove my problem on my new tank.
great tips. Mine is leaking at the sending unit and it runs to the drain line just like you said.
Military surplus GRG (Gas Resisting Grease) is great for those O rings. Sold commercially as EZ turn lubricant.
Thanks man , Im about to do this project myself, cork makes sense.. may have to reuse original screws though....

Petrolium based lubes aka Vaseline can degrade rubber over time. It can also cause the rubber to swell.
Haven't ever heard that one before. I worked as a mechanic at Chevrolet in the 90's and that was what we were were taught.

Not a bad idea

Where do I get the screws
H&H Classic has them #1190
Can you tell me where to find the cork gasket? I;m having no luck finding one
