Don't know much about 'em myself, but I did a search of the post for "blazer tank" and found a bunch of stuff. There is one really good link with instructions and pics. It is: http://www.low69cst.freeservers.com/Blazertank.htm

Good luck and show us some pics (so I'll know another "niner" to watch out for LOL)

Check out www.classicheartbeat.com . One of the guy's on the board came up with the idea, Tennman I think, it's a pretty cool way to install one!!!!!

70chevy · 07-13-2002, 11:27 PM

Has anyone installed the new aluminum tank from No-Limit.
http://nolimit.net/new.htm

Looks nice but expensive.

Low68 · 07-14-2002, 11:56 AM

I installed the no limit tank. I didn't have my bed on when I was running with the tank. The tank went in fine, but when I would fill it up full it would push gas out the vent tube

. That ticked me off. I could only fill it up 3/4 full or it would leak out. I am going to call them and ask them about that. It might be because I live in phoenix and have excesive heat or maybe because I didn't have my bed on. I need to get it fixed though. Anyone else have experience with these tanks?

Low69CST · 07-14-2002, 12:02 PM

You need to run your vent line way up in the quarter pannel or somewhere. It needs to be about 6-12" above the gas tank. Thats why incab tanks have the vent lines that go up in the piller and come back down.

kaycee · 07-14-2002, 08:12 PM

Wow another Wyomingite,Are you putting your tank in a LWB OR SWB?It should go in the LWB fine I tried a 74 Blazer tank in the swb coil rear and it no fitty

it will but the back brace needs taken out and the tank will stick past frame about 3" or so.I belive they(aftermarket) make a smaller tank for this set-up.

bigvinnie · 07-14-2002, 08:40 PM

I've got a No Limit tank, haven't had the problem that low68 is describing, I ran my vent line along the inside of the frame, coiled it once and have a paper element fuel filter pointing vertically on the end.... no worries.. vent line is visible in the upper right corner of the tank.

chevyman 68 C/10 · 07-15-2002, 08:15 PM

That is a cool looking tank, how are you going to run your filler kneck. can it be extended to reach the tail light?
