cutting gas tank neck

I have a manual and know I need to cut/section the gas tank neck for hood clearance. What you some of you used to do that, a hack saw? I was looking for a large pipe cutter like those used for cutting hot water pipes. Any thought?
Thankyou
Gary

I took a gas tank once and had a radiator shop pickle it, clean it, and cut the neck to the right size on a project corvette. It cost me $40 to have all that done.

It probably doesn't help you but I just received a 16 gal tank from Pacific Customs that has an angled-down-to-filler feature of the tank with a filler neck that is only 1/2" high at it's top enge from the tank body.

The filler is smaller and required the purchase of a smaller diameter cap, but the whole thing seems as though it was built for us.

it's their iem #201075113ab-16, listed as being for the '61-'67 type 1.

i bought a 16 gallon tank and it held only 13 gallons tops

bob, gas is a lot more now

HAR!

My tank is a new tank so no crud inside yet.... I thought about a cutting wheel but need a clean even cut. I could use a hack saw but I am sure that is a suck way of doing it.

get yourself a jubilee clip.....fit it around the neck as a guide and cut with a hacksaw......

The clip idea is simple and easy for me I like that. The idea of the new tank is good, but this is a new tank. If I screw up the cuts, then I will go with that done tank idea.
Thanks all.

Turn the tank upside down to avoid filings getting into the tank then using that forbidden hacksaw, make a light cut all the way around the neck than as you cut straight through, the blade will track straight...been there a couple of dozen times.
Some of the aftermarket tanks happen to have a slight taper to the neck and if so, you can get away with just filing the cut edges smooth and with a light coating of JB Weld as a sealer, tap the shortened neck into the retaining neck...done~

OR you can braze it with brass instead Of JB Weld .

But even a brand new tank will have cosmalall in it. Not combustable but does collect dust and trash.. Wash out the tank with water when your done.

(((and check it for leaks.)))

Use lacquer thinner to remove the cosamalall and displace the water,and put it in a hot dry place, to dry out.

Gary, in a previous life we used a coating of shaving cream to capture metal particles and toxic dust from cutting lead sleeves. Might be overkill in this case because you sound like you're being extremely carefull anyway. Good luck

Put some grease on your blade

...and avoid getting mud on your helmet!

BWAH HAH HAAAAAAAaaaaa..............

This tank does have a taper at the neck, I like the idea of tapping into it. I have a guy who can weld. Thanks for all the ideas. I am the third owner and plan on finishing this over due 20 old CMC. I just got it 2 yrs ago and this list keeps me pumped up. Let the cutting begin.......

"plan on finishing this over due 20 old CMC.
" OH you must be neighbors with Wolfgang " he's at 20 something years I believe.

Yeah, I know it is going to be a close race to see who wins....doh!
