My Truck is a '72 C20 Longbed.
I am replacing all my fuel tanks (Stock behind the seat plus the two saddle tanks) with a '73-'81 Blazer tank. With plans for a future engine swap from the 402BB/TH400 to an L96 and 6L80E I have been considering the TanksInc 25 Gallon TM15-T EFI tank. Since I don't want the hassle of the center fill in the bed. The Side Marker light modification to Filler Door looks cool and very clean, however here in California it won't work due to the size of the Gas Station Fuel nozzle won't fit in the hole. So my first idea was to go out the back using a flip down license plate however that area is too low to work (Bummer since that would be super easy and very clean!). This leaves me with going out the side coming up through the extreme corner of the bed 9" from the tailgate then out the side. I will make a sheet metal cover for the filler tube, use a filler neck grommet to secure it the inner bed side then cut a hole in the outer bedside just below and in front of the rear side marker light with a nice billet fuel door (I know it would be easier to just install it in the corner of the bed :smile : ).
Questions: Has anyone installed one of these tanks from TanksInc?
Has anyone else installed a Blazer tank in a C20 Longbed?
Any other thoughts or ideas?

Don't know if it will give any more room but did you look at the taillight mod that flips down? I did the side marker light on my step side.Why not do the side marker and flip it around so it is inside the bed ? I cringe when I see a nice looking truck only to see the filler in the floor of truck I dont mind the side fill as long as it has got a nice stock looking door

Thank you for your reply and ideas. Yes I did look at the taillight mod however the same problem exists for that. The problem here in California especially SoCal is the fuel filler nozzles are approximately 2.25

I have a 68 long box. I had the same problems you are having with where to locate the filler hole. My solution was to install on the drivers side just inside the bed behind the box corner post. I bought a flip out door and filler neck assembly from a wrecker. It came off an old Datsun pickup. That gave me my face plate. I then built a small box around it. You don't lose any cargo area and you have a smooth box side panel. The stainless steel tank I mounted between the frame rails has an elbow on that side of the tank.

Hmmm, that’s not a bad idea. I have made the inner panel already and have the S-10 filler door. The issue I have is for some stupid reason GM trimmed the area that holds the marker light so I can’t mount the door without welding a plate to the area. I just don’t want to damage the paint. I’m going to mock up a test section and try some JB weld to see if it would be strong enough to put up with the constant pressure from using.

I put in an aftermarket Blazer tank in my 71 K10 swb fleetside. I ran the fill pipe and vent horizontally left to the inner fender. Then 90 degree turn up and angled to the center of the top of the inner fender, tire side. I used a hole saw to drill it, the cap is inside the box on top of the inner fender. I used galvanized water pipe so it wouldn't get dented from rocks off the tire.
