We are needing to remove our gas tank to have it flushed out. Also the strainer on the sending unit needs to be replaced. It has corroded with age. I should mention there appears to be some rust residue in the bottom of the tank. Thanks in advance on how to best approach this, and the steps for removal. Frank & Paula Lowery. NCRS #28045.

Re: 69 Gas Tank Removal
Frank and Paula-----
It's pretty straight-forward to remove the tank. Drop the spare tire carrier out of the car, remove the fuel line and fuel gauge electrical connections, remove the bolts holding the 2 straps, and lower the tank. For 69 models with Rochester carb, you will also have to remove the fuel return line from the upper right side of the tank. You may or may not also have to remove the rear (crossmember-back) exhaust system.
I don't recommend re-using most fuel tanks, especially if they have sufferred from any significant internal or external corrosion. Exact replacements are not that expensive. Some folks think that the tanks are dated on the lower surface of the tank near the fuel pick-up orifice. Indeed, there is a stamping there that LOOKS like a date, but I don't think that it is. The original stamping on my original-owner 1969's tank was "2-70". Since my car was built in September, 1969, I really don't think that the "obvious" date coding is actually a date code. The "date" can't be seen with the spare tire carrier mounted in the car, anyway.
A replacement strainer is no longer available through the GM parts system, but one MAY be available through Delco. Also, Corvette vendors like Dr. Rebuild and others carry them.In Appreciation of John Hinckley -
Re: 69 Gas Tank Removal
Joe - when I removed my original tank from my 67 (it is still in excellent shape inside and out) the top surface had some faint blue ink stamping that indicated 2-67, and my car was built on May 11, so naturally, I assumed this was the date. It also says Long Ternes or something like that...I don't know if this was a tank supplier to GM, but, fyi, I bought some used saddle tanks for my 81 pickup to replace the original tanks (had a problem with pinhole corrosion on the original tanks). The junkyard had taken them out of a 73 pickup, and they also had this Long Ternes designation in blue ink on the tops, and a date with a 1973 vintage....again, seemed like a date code. Are the marks on your 69 this type of ink stamping, or something else? Thx!...CraigComment

Craig-----
No, I'm not referring to an ink stamping or anything else on the top of the tank. The specious "date code" which I'm referring to is on the bottom of the tank, EMBOSSED on the ring around the pick-up orifice as I mentioned in my earlier post.
I am not aware of any company other than O.L. Anderson that manufactured PRODUCTION fuel tanks for any 53-74 Corvette and, perhaps, even later than 1974. That's not to say that there were not others, but I don't know of any.In Appreciation of John HinckleyComment

Re: 69 Gas Tank Removal
Thanks Joe - sorry for my confusion. My 67's tank is O L Anderson with the logo....maybe the Long Ternes is a steel supplier to O L Anderson, and it is the dating of the sheet goods from the suppler. It is very very faint, almost indiscernable...same on the 73 truck tanks. I didn't notice any embossing in the 67 tank near any of the openings. Thx again!...CraigComment

Re: 69 Gas Tank Removal
As Joe says, the repro Quanta tanks appear to be dead on. If you insist on reusing your original gas tank though, Eastwood (I think) makes a gas tank sealer. From what I have seen, once your tank is cleaned of residue and rust, you pour this mixture in your tank and swish is around to coat all of the surfaces. I don't know how long it lasts or how well it works, but I have corresponded with some who have used it and seem to be satisfied.

Repro Tanks....
a thread comment is the gas tanks from Quanta are 'dead on'. Can't say I've really seen that many of them but the two or three units I have seen looked right on the money to factory orignals EXCEPT for the OL Anderson emboss which was cocked 90-degrees from the orientation of true original tanks.
Is this something that's changed recently at Quanta or have I been duped by the small sample analysis/conclusion syndrome?
I've got to agree with Joe--the price Quanta gets for this reproduction part is VERY fair. Heck, IF you can find a local plater with a 'gal' tank big enough to emmerse your original gas tank, the price of the repro has to compete with your out-of-pocket to restore an original PLUS you've got fresh steel all around!Comment
