Gas tank relocation

[Chevy nutcase]

Was ordering a bunch of stuff to redo the floor, carpet and seatbelts in my 66 c10 and I want to relocate the gas tank and I have a question. I know one way this was done was to use a blazer tank which requires some modifications to be made to the bed crossmembers but do the kits offered by a variety of sites also require the same crossmember mods? I was thinking of getting my tank from Brothers/Holley and their site says very little on the subject and I don't see why a product specifically made for this would require cutting and welding.

You can mount the tanks without cutting, but of course it's going to hang down lower. The other thing is when I did mine I had to use nutzerts for the bed boards above the tank because there's absolutely no way to get a nut started for those 4-5 strip bolts unless you put the bed boards in before the tank.

I used a Boyd's aluminum tank mounted with their mounting kit. It is necessary to remove a small cross member behind the rear axle. I would assume any tank mounted in this location would require the same.

I used the basically same one as Bobby B

I used the LMC kit. It worked out well.

I used one from a Jeep CJ5 and a fill spout in the box that came off a Dodge truck. Maybe it's a little small at 14 gallons. I had to use a different fuel gauge.

This is what I did using the LMC truck fuel tank

That's incredibly cool and I'm wondering if your truck is a 64 that probably didn't have original reverse lights. My 66 has them and I think state inspection laws would frown upon this mod BUT I am going to inquire about it. I really don't want to cut a hole in an otherwise pristine bed but lack of options will likely say otherwise

I put mine in the rear stake pocket.

Here's a thread I started before doing mine. Granted I was more concerned with the exterior view rather than the filler location, but I figured out a semi discreet option for it too. https://www.67-72chevytrucks.com/vbo...d.php?t=621177

I kept the reverse light on the right side.

I moved the tank to under the bed (pictured). To fill up, I will need to access the bed, however I have also added another pic of an idea I found online (not my idea, not my truck). But I thought it was pretty cool. Your gas line would need to run through the rear and I thing there are some Blazer tanks already designed for this. EDIT: Sorry but I cannot figure out how to add photos... I will look into it.

I used a 64 mustang tank. I did open the top of the frame rail about a half an inch on each side to fir the tank up a little higher and reversed the rear crossmember. It tucks up in very nicely.

Normally I wouldn't consider Ford parts but your install looks wonderfully clean. I do have a few questions though. One, how well does the ford sending unit cooperate with the trucks fuel Guage. Two, if I had to guess it looks like when you had the rear crossmember off you slid the tank mounting flange into the frame channel making this mod impossible with the bed on the truck.

I have custom gauges so I just ordered a gauge for a ford. The front crossmember will never need to come out to remove the tank, if needed.

As I understand it, fuel gages are basically ohm meters and while I know less than nothing of ford or mustangs I'd imagine their gages are the same. Without buying and testing this sending unit I'm wondering if there a way to tell if it's the same as chevy

[jzorn94]

Tanks Inc. has a device to adjust the ohms between the sending unit and the gauges. I haven't used it, but I saw it on their website. It's part TAN-MM for $90.

The '64-1/2 to "68 mustang sending units are 73-10 ohm units.

I just ordered Boyds Fuel tank and Hagan Fuel door for my 1966 C10. I plan to attempt to put this flush looking fuel door on the INNER wall of the bedside IF I can make it work (with modifications) within the 2 7/8 inches between the inner and outer bed wall. It will be September before they arrive.

I got the idea from someone on this forum to make the filler in the corner. Only downside is it's a slow fill but not too bad.

Mine. Tank is custom one off.

Anybody have direct experience with one of the tanks?

No experience with them here but looks like a decent product and I love how they have a variety of sending units with varying ohm ratings for specific applications as I want to keep my stock gage. Seriously considering this one because it's 18 gallon and won't hang to low. Thanks for posting the link

I used Tanksinc's USPT universal tank. It has two options for filler placement.

Tech support at Tanks Inc says this tank will extend 6-7/8” below the mounting flange, in case you want to measure twice and pay $$$ once
