Blazer Tank Install With Pics. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

RED71CHEVY · 11-01-2003, 01:14 PM

is the tank galv. or plain steel, do you need to use a gas tank sealer on the in side of the tank to prevent rust?
why use the steel tank if the ABS tank will work?
did you use rubber strips between all mating surfaces?

Thanks for all the information and time you take to post. I'm about to start this same installation and this is very useful.

71HUGGER396 · 11-01-2003, 06:10 PM

I'm getting ready to do this next week and I was worried about how low the tank was going to hang down. I'm running a 4" drop in the rear. When I was holding the tank up to the frame I was trying to see if I it would go in the frame instead of under the frame. I thought about removing the cross member in the rear of the frame and sliding the tank in that way. My truck is completely torn apart so I don't have my bed on it. I was wondering how much I could raise the tank before hitting the bed???? Do you have any idea?

*Randy70C-10* · 10-29-2003, 03:26 AM

Nice job!

Hey, can you get a pic of what it looks like from the rear? I'm just curious on how much of the tank is visible below the rear bumper.

nu2-72 · 10-30-2003, 08:53 PM

I thought this was a modified Blazer tank to fit these trucks? Or is this company making Blazer tanks only?
It seems that there were several items that need to be addressed. I mean if the builder is just down the street from the Truck Shop, maybe you could do some R&D for them and tell them to increase the filler neck during the build. Also increase the hole size/angle so the mounting bolts fit correctly. How does the filler neck line up with the side marker? Maybe they could adjust the angle there also if needed.
I would like to do this swap but do not want to work hours to cram and fit it.
It would be great to have the details worked out and built right from the start.
Like buying headers and then massaging (hammer) the pipes to clear things.
Let us know.

nu2-72 · 10-30-2003, 10:24 PM

I was just thinking that if they make them, they might consider a filler neck in different configurations. As you say, side-marker, bed fill or original Blazer. Options are nice and all that is involved is the soldering of the different necks. I am lazy and would like to order a custom fit. All done and ready to install.
Keep up the good work.

lukecp · 10-29-2003, 02:41 PM

Nice job...now what are you going to do with all that free space behind the seat, lol

Huck · 10-29-2003, 09:14 AM

So much for the easy parts---can't wait to see the step by step on the fuel filler work. Tennman's porcess is nice but seems to leave out too much detail so perhaps your's will either show the way to side market filler or scare us to in bed filler!

I've got two tanks to install and have been putting it off till I'm comfortable with where and how to do the filler. Also hate the idea of cutting the floor support on a metal floor~~~~

bluec10 · 10-30-2003, 11:35 PM

I really appreciate the effort you went through to post the pics and the description. I want to do exactly the same thing on my '68 and put the filler behind the marker light.

Out of curiosity, what are you doing with the old filler cap? I'd like to keep mine where it is for original appearance.

A.P. · 11-01-2003, 03:29 AM

Great job.

rambler · 10-29-2003, 12:01 PM

TTT,,, I agree, this would be great in the FAQ section, when I convert my tank!

oldcarbuff · 10-31-2003, 11:07 AM

do you think it would be possible on this type of tank to run a filler tube into the fender on a stepside? I am torn between the clean look of a filler in the bed floor, and the sure knowledge that at some point I will have the back filled with sheets of plywood and need to get some gas

gbkwork · 11-01-2003, 12:32 PM

This couldn't have been posted at a better time for me. I plan on tackling this job next and will be looking forward to the side-fill pictures / instructions.

I am running bags at the rear...do you think this tank drops too far below the frame? I'm not laying frame and have no intention of ever doing so (I'm at about a 4.5" / 6.5" front/rear drop).

Thanks again for the education. This message board is great!

Carl71 · 10-30-2003, 10:20 PM

Great job on the pictures, wish I had that when I did mine. Your right on the time with the bed off took about 2 hours of actual putting it in after we figure out what we were doing.

The Tank from The Truck Shop

jorgensensc · 10-29-2003, 02:55 AM

Feel free to paint it whatever color you like. I chose to use rubberized undercoating to help avoid rust.

I removed the spare tire bar by grinding off the rivets holding it on (sorry no pics from before).
