Fuel tank questions.

Yes I know this is like beating a dead horse! LOL I've done some research as I have the past year so about the gas tank and I just have a question. So I am ditching my Wrangler gas tank due to the fact that it's kind of small and leaves a lot of room where it sits and is a pretty small tank and the filler neck is only an inch wide. So I am thinking about using the 87 Blazer tank. does anybody have any pictures of the setup for this so I could see how it looks? Also is it an S10 Blazer tank or a full size Blazer tank?

Re: Fuel tank questions.

I done some research on it and came up with nothing, so I went ahead and bought the wrangler tank for mine.

Re: Fuel tank questions.

What you putting this in?

If I remember correctly, the rear most crossmember would have to come out for it to fit up against the frame. Otherwise I would have to drop it down lower than I'd like. I have the tank and didn't want to do this so I went with the wrangler tank. 1inch filler neck is not an issue at all. And at 17mpg, I get about 250 miles which is about a weeks worth of driving for me. I also like stopping at the gas station. I usually get a couple people asking about my truck every time I stop.

I may still go with the suburban tank and just have it drop down low. I haven't decided.

Re: Fuel tank questions.

I put an 87 suburban tank in my long bed, it fits great and works great. 25 gallon, I think the part # is GM15C. I wasn't sure it would fit in a swb, but check out this thread, others say it will: http://67-72chevytrucks.com/vboard/s...d.php?t=766312

Not sure what vehicle you're using it in but the S10 blazer tank may be too wide for any C10s other than 60-62. When I ran my 383, I used a 78 Chevy van tank that fit perfect. For the LS engine, I bought an '87 van tank but it hung much too low for my taste. Ended up with the 94 S10 Blazer tank that
has worked out great. There are at least one or two trucks I've seen on the forum running the '87 full size blazer tanks for certain. We'll be installing an LM7/4L60E into my brother's 66 swb Big window in the next month or so and the '87 K5 tank may be what we use.

Re: Fuel tank questions.

I used a 87-91 Blazer 31 gal tank on a short bed.
Took fair amount of work for it to fit. Had to take out the spare carrier crossmember, move rear member all way to end of the frame, add 3" to the rear frame rail and notch the cross sill on bed itself.
And remember the filler is on passenger side. Worked for my idea but some might not like it.

I wanted it as tucked up as possible. Tank hangs down 7" from bottom of the frame rail.
The filler neck comes over the rail and landed exactly where I wanted it.
I welded a '72 Blazer interior fill hole inside the bed then made the neck exit like a K5 but on passenger side.
I wanted it to look stock, just on the wrong side. It all lined perfectly.

Re: Fuel tank questions.

Irish1941...can you post some pics of what you did concerning extending the frame rails and relocating the rear member? Did that impact your bumper location or mounting? I like the way you did the filler - looks good!

I put the same tank in my short bed and was wondering about how it would affect the bumper, tailgate, etc. Unfortunately, mine is FAR from finished. Due to a relocation, life, etc. it’ll likely be a while before I can get back on it.

Thanks for the help.

Re: Fuel tank questions.

here's a question, how about a new 69 Camaro tank with a bed fill tube welded in place? could you then raise it to flush with the frame not using the drop license plate option " which I think is cool" but able to raise it higher for a lowered truck?

Re: Fuel tank questions.

I used a Rick's tank, with bed fill option. Made in USA (Texas). Awesome tank.
