1984 Trans Am that has the original gas tank so I want to replace it before any issues. Basic tank with sender, LG4 motor has mechanical fuel pump so no fuel pump. Any recommendations on where to purchase a tank and sender as I have heard of nightmares with fitting and fill neck issues, part #'s would be great. And yes I know its not an easy job because everything has to be dropped. Thanks

 

I have the full aeromotive stealth setup. It uses a specter tank. It fit well but the filler neck was 1 inch off. It took 30 seconds and a 1/2 piece of pipe to fix it with it in the car. Tuebtank came painted gray and matched my stock tank really well. Just a heads up, i figured my stock 82 tank would be nasty inside back on 2022. It looked brand new inside. There was no need to replace it. But i did cause i had a whole new setup. Theres no way to know till its out. I wish I welded in an access panel cause *** that job.

 

Thanks for the reply. Do you mean a Spectra tank ? And if you could explain more about the modification you had to do to the neck.

 

Yeah, i knew it was something like that. It was stamped in the tank. So the filler is all steel. It has a sort corrugated/flexible section at the base. Once the tank was in and seated the filler wasn't centered in the hole in the body/plastic filler panel. It was 1 inch too far forward. So w the filler panel out, I inserted a 18in long 1/2 inch ratchet extension and used the leverage to gently bend the filler back. It was super easy

 

Got it. Any tips when removing or installing the new tank ? Looking at Youtube it looks like a nightmare !!

 

Do it on a lift and patience! I don't have one so having the car up high. Removing all the suspension so the rear end is freely movable and out of the way. The exhaust needs to be out of the way also. I didn't have to remove the drive shaft/torque arm/brakes but all the other parts on the rear needed to get unbolted.

so pretty much taking the whole back a part!

Id rather pull an engine!

 

Be sure to take off the T fitting for the rubber brake hose from the pumpkin; otherwise that will be the only thing supporting the weight of the axle.

 

I have a 4 post lift so I should be able to jack up the rear and support the rear frame and lower the alxe. Any Ideas for a sending unit, I cant seem to find one ??? My car does not have the internal fuel pump, two wires only.

.

 

 

The 82-84 senders are tougher to find. Ive seen people find them on ebay and hawks. I used an aeromotive but that has the pump built in. If you search around this board you may find some recent info on availability/sourcing.

is your sender bad?

 

My sender works but being over 40 years old I dont want to take any chances. I have read people using the ones with the pump and just using the two wires.

 

Anyone order a tank from Rockauto ? I have ordered small parts with no issues. And is there much of a difference between Spectra and Dorman ?

 

Recommendations for replacement gas tank

If Dorman makes a replacement tank for your 3rd gen, don't buy that one.

 

Any input ordering a tank from Rockauto ?

 

Spectra tanks seems to be fine. In fact, my Aeromotive Stealth system may actually utilize a Spectra tank. Their sending units are decent as well. Can't comment on Dorman tanks.

 

The aeromotive tank is spectra. The only aeromotive parts is the sender/pump. I haven't heard anything about dorman tanks. Id get new straps and rubber insulators.

 

Thanks for the replies,. I will be going with a Spectra tank. Anyone order a tank from Rock Auto with sucess ?
