James - let me see how the 1st one goes. Thanks for the offer!

Sam, that's what I thought. Usually..... the cause for that situation is becuause the cap ring is for an EEC tank which used a different (non-vented) cap. The depth of the cap ring lip is different to prevent the inadvertent use of the wrong cap - and thereby potentially sucking in the tank!

My advice (albeit unsolicited!) is to use a Quanta tank! A little pricey, but.....

Marlin - the Spectrum tank looks real nice. Mikey promises me even a doofus like me can unsolder the old cap receiver and put the correct one back on. Me being a cheap-skate and all , I gotta try this way 1st before buying a Quanta. BTW - I called Q and they would not sell the cap receiver separately to me. I got the feeling they do not make them there anyway (subcontractor?).

I had a tank with a small hole punched in the bottom once, and soldered a penny on to the hole.
That's the short version.

The long version cost me some eyebrows. Seems the metal actually absorbs a bit of petrol over the years. I completely emptied the tank. Let it sit for a day. Ran a garden hose in it until it overflowed for about 5 min. Emptied the water. Let it set til the afternoon. Set the tank up on a work bench, cleaned the spot really well, went to solder the penny on, and as soon as I hit the hole with an open flame.... BOOM. Of course, I was standing right over the hole for the sending unit.

Fortunately, it only slightly balloned the tank.

Mikey says old shop trick...use dry ice to displace the oxygen during soldering operation.

Sam has requested the neck from the old tamk. I cut it out yesterday and will send ASAP. After that, I am not responsible.

The Hippie makes sense since Quanta only sells Spectra,(Not Spectrum),Premium gas tanks so buying one from them won't resolve your problem.
Quanta Part# GM 46-D 1970 Nova Gas tank w/o EEC for $189 + ship...includes filler neck.

Be sure to catch it on video. It could be informative, .................................................. . or entertaining!

Conducted the procedure this weekend. Mikey didn't steer me wrong. Dry-ice worked like a charm and the original gas cap has been mated back with the cap receiver. Thanks for all of your input. I feel much better now!

P.S. the notion of an exploding gas tank made me think of the tank as a rocket ship, so I made a launch pad!




You can see the dry ice doing its thing here. By the time i was done the project and ready to mount the tank back on the Nova all of the dry ice had disappeared with no residue.

Sweet work. Glad it didn't go BOOM!
