New stainless steel gas tank
 
2 Attachment(s)
I installed a new stainless tank in my 68 lemans today . Came with new stainless straps, stainless sending unit, top pad, strip pads for straps, and some generic 3/8 3" pan head bolts which I didn't use as a package deal. Install was kind of tricky because it seams the tank from side edge to side edge was a little wider than my old tank which I didn't measure beforehand and my exhaust seemed to be in the way. Undid the hangers and got each pipe to move 3/4" or so and bent one corner of the tank with a pair of nines enough to clear. Other than that install was fairly simple. The neck on the new tank seemed to be about 1 3/4" longer than old tank (which I don't think was original) as shown in pics but didn't make a difference. most importantly, the neck was pre bent already and needed no further "tweeking" for proper clearance of bumper for gas cap. I didn't put any coating on the tank and hope I won't regret it. I did use spray adhesive for top and bottom pads. Overall I'm impressed and hope it lasts!!

Good deal!
I don't see any pics. What's this bottom pad that you speak of?

The pan to tank pad was like a not as dense workout pad/foam material maybe 3/8-1/2" thick. It all came really well packed. Box inside another box.

Forgot to mention I ordered the 69 Gto tank for my 68 lemans. It had filler neck vent as well as 1 vent near ront of tableland on passenger side. Old tank for sale in the Atlanta area. Pressure tested with soap bucket and hold air. Inside looks great and no rust. Needs cleaned. 25$ as I'd hate to junk it

'69/'70..That's why you didn't have to bend that neck. Speaking of which, nice...the neck looks polished.

That looks nice. I'm not sure I'm a fan of that foam rubber pad though. looks like it'll trap moisture up there and stay wet forever.

Did all tanks have the big blanketed sheet over the top of the tanks? North posted a pict on the originality pict thread I started last week & you can see the insulator hanging on the neck side of the tank. curious.....

That SS tank sure does pop under there!

original upper tank insulator pads were tar paper like whats on the floor pans.

Greg Reid 03-04-2018 02:31 PM

I was hesitant to say the same thing Dennis re: the foam...probably does't get a ton of water up there though unless the trunk leaks..
I got an excellent pad from a user here by the name of 'pglade'. In fact, I got two of them from him. Identical to the original equipment. A tar paper like material with a thin plastic coating on one side.
Haven't seen him around lately but he used to post a lot on the big Oldsmobile forum.

These tanks are awesome.....no need to worry, it will stay looking
new indefinitely with no tarnish. I put the new stainless sending unit in mine as well, and the fuel gauge reads 3/4 when it is full, so I wish I had left my original
sender on my car. I have a brand new GM one on my shelf, will swap it out one of these days.

The only proviso about stainless tanks is surrounding corrosion. If you install a stainless tank (or any other stainless part for that matter) in a car you can create corrosion cells with any regular steel that comes into contact with it.

Of course the way a typical collector car is used (indoor dry storage, no winter use etc) there won't be an issue anyway. (which is why you don't really need a stainless tank ;-). But if you were to use it in a corrosive environment like driving year round or wet storage any regular steel that contacts the stainless will corrode many many times faster than it would otherwise.

This is because when stainless steel is paired with regular (carbon steel) the regular steel becomes the noble metal and it "sacrifices" itself to protect the stainless.

Anyone with a boat who ever put a stainless anchor and a regular steel chain knows this all too well when the last link of the chain that connects to the stainless anchor dissolves away!

north you are so right. But he's in Huntsville where the city shuts down for the possibility of Snow. No salt here You north-erners got all the salt.
