I'm putting a 31 gallon blazer tank in mine. You gotta remove the spare tire bracket and scoot the rear crossmember back. Tank is like $78 from rock auto, $40 for a sending unit and a couple bucks for tank straps at Lowe's.

I'm running a 25 gallon tank for a 1989 blazer that I ordered from Amazon that fits .. same dimensions as the 31 gallon SuperHondaz is running just doesn't hang down as low. plus its baffled so its set up for fuel injection if you ever decide to go LS. Same mods to my cross members that he did to make it fit. I have had the 31 gallon and now the 25. I prefer the 25 because it doesn't hang down nearly as far.
This is the one i bought

And Here's some pics so you can see how it fits the frame rails. same fitment for a 31 or 25 gallon

I've got a question about your fuel hose. Isn't that flex hose designed for water? If so how will that hold up with exposure to gas?

Looks like water hose. I've used that same hose on my jetskis for fuel though and it's really tough, lasted 10+ years

Yes it is not specifically designed for fuel. it was/is a very temporary fuel fill before I got my bed on with a bed side filler. We have had fuel sittin it this on another truck for a very long time and its still holding up great. I wouldn't use it for a permanent set up but for temporarily keeping fuel in the tank rather than sloshing out it works great ha.

Where are you guys going to run your filler neck at? I'm thinking of using some aluminum tube and rubber hose to run it to the driver's side saddle tank fuel door, options are always nice.

Im personally just gonna run it with a newer body style door through the bedside just in front of the side marker. . some dont like it but its simple and works ha. I like your idea with your stock door but man thats a long fill ha. I had a side marker fill on my last set up and hated it. living in cali the boots at the pump are just too damn big

Ya, I believe there should be enough for itto make it down into the tank, prob a 6" total drop?

I put in a 20 gallon jazz fuel tank with a bed fill

I would think that would be enough unless you have to park at a slope for any reason. I know when my truck was on bags there wasnt much drop from the side marker to the tank so i would air out the opposite side to give myself easier fillin haha.

What year did that gas door come out of? looks nice.

[Smitty]

Not sure. My brother picked it up for me. But couldn’t remember what it came from. Did cut the whole pocket with the door, cable, and release Assy.

You could prob make that work but the dimensions are fairly small so you would prob need to make brackets to mount it. as for the sending unit, the 67-72 trucks use a 0-90 Ohm sender so seems like it would work just fine for that.

That looks really nice. what is the "typical" door from? I am looking for a door to put in mine but am having a hard time because the junk yards no longer let you cut just what you need, they try to charge you for the whole bed panel!

'IF' I remember correctly that filler door came off of a late 80's early 90's Chevy pickup. But that was almost 20 years ago. I was able to get a section from a bed panel from a truck that had been T-Boned. The inner bed panel came from the same year range of a Mazda pickup. Yikes! A foreign truck part on my truck.


Some pics of the installation.

Nope the body shop that painted the truck made it. Well the owner's Dad made it.

Devil pup, will that tank work on a coil spring truck? I measured my frame today and it’s not wide enough or long enough. The tank measurements are 29”x29”x 11, according to the specs on the tank from amazon. Thanks Kirk
