The Stovebolt Site Forums The Shop Area General Truck Talk 1961 K10 fuel tank relocation

I am looking to move the tank to the rear and put the filer in the tail light on my 61. I don’t find a tank the says it fits the 61 K 10. I do find some 15 gal universals tanks that size wise would fit between the rails. Is there some issue with fitting a side fill tank in the 61 4x4? Is there another option that bigger than 15 gal. Thanks

Just a question, have you confirmed there is enough space between the top of the frame rail and the bottom of the bed to get the filler hose over to the taillight?

Would this work? Tanks Inc has lots of tanks to look at...

I agree with Mike. Check out Tanks Inc in Iowa. They may have something or could build you what you need. I know others on this site have utilized OEM tanks from other vehicles. Hopefully, one of them will chime in and help solve your dilemma.

If all else fails, you may just have to grab a tape measure and hit the scrap yards.

I agree, 15 gallons doesn’t seem big enough for a full size truck.

Good luck.

Thanks! That could be an issue, There is 2.25 inches. I am fairly sure I could shim the cross supports to get a little more. The truck is lifted so I would have to drop the gate every time I filled it with a bed fill, and I don’t like the idea of dragging a hose over the paint.

Standard tank is 16 1/2 gallon, RPO tank 20 1/2 gallon.
I found a nice RPO tank in a salvage yard C60 several years ago, helps with range anxiety!
Didn't matter much when these rigs were new, gas station in every small town.

15 gallons may not sound big enough, but if this truck doesn't get driven a lot a smaller tank would reduce the amount of "go bad" that happens when today's gas sits in the tank for months.

I planning on it being a driver. I got a drive-chain engine transmission from a 2004 1500. Still got to get a right side dump transfer case. I think that set up will put me at 15-16 mpg.

Gary - Here is one of several older threads related to moving the fuel tank as you described. But it (and the other thread referred to inside this one) might have more connection with your stated later engine as it includes a provision for an in-tank fuel pump.

Also, if you want to go with a larger capacity tank, this 18 gallon tank might work if you have the space to fit it in.

I used a 21 gal side fill kit from one of the vendors, don’t recall which one, in my 66 c10 short stepside. I know several vendors sell it as I viewed a how to U-turned video from Brothers. Details are in my Project thread. FWIW, tank is said to be a Blazer unit. Thinking about it, I believe it came from CJ Pony.

The tank I linked above has a 1-1/4" filler neck and 1-1/4" fuel hose has a 1-3/4" diameter, so you should be able to use that tank. I believe it's also setup for using a in-tank fuel pump which you might need with your newer engine setup.
