Gas tank neck

Does anybody sell just the gas tank neck. I am removing tank from behind seat but am not doing body work at this time. I am afraid to cut neck off of existing tank.

Re: Gas tank neck

I seen one post the fellow welded a bolt to the gas cap used a bar and a wing nut to secure the gas cap to the truck

It serves double duty close the hole and wont allow a gas station attendant to fill your cab with gas safety feature

Thumbs up Re: Gas tank neck

Fill the tank with water up to the bottom of neck and cut it off. It want blow up with water in it! You can even turn a fan on and keep the neck in the wind stream.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.

Re: Gas tank neck

My tank was outside for about a year open to the elements. I didn't even think of sparks or heat when I took my sawzall to it last month.

Re: Gas tank neck

Depending upon the year, it may not be necessary to remove the filler neck. I removed the tank from behind the seat of my 70 C-30 as one piece.

Re: Gas tank neck

You can see this in my build thread post #13, https://67-72chevytrucks.com/vboard/...d.php?t=782232

I decided to keep the original fuel fill hole. I welded a stud onto the back of the fuel cap and used some washers to double-nut it in place. I didn't want to hack off the original filler from the tank, so I don't have any of the filler neck showing.

Re: Gas tank neck

This is great. How did you keep from burning the finish off the cap while welding?

The stud doesn't touch the outer part of the cap. There's an inner part of the cap that I could weld to.
