Gas tank ???

[84 c10 o skool]

Hey ya'll,

I just drop both tanks on my 84 chevy c10. Both had rust inside. So before i re-install the motor I'm going to change these out.

Gonna buy new ones. Any recommendations.

any difference from the black painted ones and the steel ones?

thanks

I got mine from Classic Parts of America (classicparts.com) five years ago. No issues.

Make sure you get the right ones. The filler necks were 1/4" smaller on the earlier squares (73-81).

I got mine from advanced auto, they actually had it in stock!

I then painted it with bedliner

I have a friend that can get me a discount from oreily's auto parts.

The brand is spectra premium.
There jus steel not coated

I have a spectre premium on my passenger side. Good quality and it holding up good.

Have to consider the same on my 84 C 10. Considering the rear mount one similar to the one listed in the LMC catalog.

Why between the frame rails in the back? Yeah, it's between the frame rails, but it's behind the axle. One third of all accidents are rear-enders. I'd rather have them outside the frame rails on the sides. T-bones are much more rare.

I got both tanks in.

Seems like the have a grease coating inside and out.
Do I need to flush the inside of the tank out??
If so with what...
Thanks

According to Spectra, don't worry about it. It's impregnated in the tank.

They also say do not use any type of gas tank sealer. It will not adhere and it will gum up your fuel system.

Here's what I found on the net in a mopar forum:

As everyone is aware of, I had a new tank from Spectra and sealed it with Bill Hirsch ethanol resistant sealer. Yesterday I
started to set the new tank under the car and a tiny white particle drifted out of the sending unit hole.The sealer had all come
loose from the inside and was nothing but bits and pieces about the thickness of toilet paper. I talked to Hirsch and they hadn't had this problem. So I called Spectra(1-800-565-5524), told them my problem and they informed me that new tanks
are manufactured with a corrision resistant type oil right in the metal and they say NOT to use any type of fuel tank sealer
(no matter how good a product) in their tanks. The sealer will not adhere to the inside of the tank with anticorrision material in the metal . This anticorrision material is not just a coating on the metal, but is impregnated into the metal when the new
tanks are stamped out.
To make a short story or tale even longer. If you get any Spectra fuel tank, do not seal it period.
Incidently all Spectra tanks are warranted up to 20 years using ethanol E20 or less. The company spent over 10 minutes on
the phone explaining all this to me and it was nice to talk to a company that actually gives a damn!
The only bright spot here is that I "discovered " all the sealer loose in the tank before I installed it and put gas in!

Cool.
Thanks man.

Could you paint the exterior with spray on bedliner? Or just leave them as is?

 

[rich weyand]

I left mine as is. Then I can see what is going on. 4-1/2 years, no rust.

With bedlliner or undercoating, if water gets behind it 1) it will hold the water against the tank and 2) you can't see what's going on.

Sounds good.

Less work for me! For once.

Thanks for the help!
