New Gas Tank!
Well, I removed my gas tank yesterday. Found a small hole in the top edge where the strap was. Lots of rust inside as well and no sign of a build sheet. I ordered a new tank from Quanta.
For those that have done this, how many have painted/treated the outside of the new tank before installation? My car is always garaged and I don’t drive in the rain.
I also have a fuel filter question. My Qjet internal filter was removed do to the inlet threads being stripped beyond repair and then sealed. I have a filter between the pump and carb using rubber fuel hose. I don’t like the look and the close proximity of the filter and hot heads. Does it matter if the filter is installed between the tank and pump? I was thinking of putting the filter in the rear of the car with the tank.

The closer you can mount the filter to the carb the better since it would filter all the lines and the fuel pump as well. Other than that, there's no reason it can't be mounted on the frame rail like most modern FI cars/trucks. Note that there is a filter sock on the tank pickup that should be replaced during tank replacement.

Hi apl,
Since the tank is in such a protected place I don't think it needs to be coated with anything, either inside or outside.
I'd just be careful installing the new anti-squeak cushions so the tank straps don't scratch the plating on the tank.
Good Luck!
Regards,
Alan

I just installed a new tank for the same reason. After cleaning the dirt of 40 years I too found small holes that eventually turned into bigger ones. The dirt and the straps must have kept the gas in. Anyway, I sprayed the new tank with a good coat of Rustoleum gavanized protector; mostly, looks like gray primer. I replaced the filter sock and gaskets. In leu of the paper tank straps; I had some old scuba tank straps(nylon webbing) that I used on the frame to support the tank for anti squeek. I also used them on the thinner tank straps. It should hold down on the friction and noise, and last for a very long time. I dont have a pic yet and the car is still on jack stands while I work on the trailing arms.

I’m getting all of the necessary parts and stuff ready to install my new gas tank. When installing the new gasket between the filler neck and the tank, should I use some kind of gasket sealant or install it dry?

I don't know if this stuff is any good (saw it on Two Guys Garage)...

Suppose to protect unfinished metals...
But if it does what they say -it's a little expensive at $60/quart- it's still cheaper than a new gas tank and could use it on other unfinished metals(alum as well) to protect them.

When I did the body off on my 79 I took the old tank out, soda blasted it and painted it with POR-15. After putting gas in it to see if there were any leaks I noticed that there were several. So I fabbed up a new aluminum tank...

Under the tank there is a bracket bolted to the frame.
This is the procedure: empty tank, remove filler neck boot, remove the bracket, lower a few inches and disconnect the fuel lines on the tank.
After you put it down, pay attention to fuel lines.
It seems difficult, but it is very simple.
Sorry for my English.

In my 1970 I had to drop the mufflers to get the tank out. A lot of manipulation and twisting. Wear safety glasses, alot of dirt and crud up and around the tank.

I'm assuming if I have to do it I will take the spare tire bucket out, the mufflers off, clear it out to do it. Right now the exhaust is at the end of its useful life and I'm having a new one put on in early Feb. when I get back from a trip to Colorado. I may have the two #4 and #8 bushing's replaced at that time as well. The right hand ram's horn manifold has a crack in the casting and that will be either repaired via weld or more likely replaced so the major work will then be done on the car.

the bushings I refer to are the body where it bolts to the frame, the back two, one on each side. Those two are rubber and look pretty much like cauliflower even though there are no sqeeks and movement. Should be easy enough to do. Also, four new shocks will go on as well. Don't know the existing one's provenance though the bolts are really solid with rust and the barrells of the shocks look pretty old. Rides well enough but I want to start fresh with knowing under my ownership when things were put on. New shocks in hand for installation.
