Gas Tank Options

[amcordo]

Anyone ever seen a plastic, or even aluminum gasoline tank for a 109 (preferrably under rear-end type)? I've searched googs for a while with no luck, but I'm hopeful someone on here can tell me it exists.

That's what we made for my truck to replace the original tank I put a hole in wheeling

That's nice work! Did you make it or did you commission a welder to build it? Reason I ask is that I'm curious--why only a few bends and lots of welded seams instead of a lot of bends with only a few welded seams?

Nice looking tank.

Thank, the reason the tank has so many wells is we used a thicker gauge where the sending unit goes inorder to give the bolts more to bite onto. When I make some more tanks I will probably try to come up wither some nuts to use instead of the thicker gauge aluminum. We als made the tank wider to gain about 5 additional gallons

I think a year or so ago firemanshort had a factory aluminum tank from a Norwegian 109, so they must be out there. I haven't seen anything in plastic that would work without fabbing mounts and fillers.

That's true, now that you mention it... Here was the link.

In the aviation industry, they rivet these floating nutplates to the underside of aircraft skins for applicatons like yours. Solid aluminum rivets are used. The nut "floats" a bit in the anchor plate so precision alignment with the sender holes isn't necessary:

I'm sorry onecross (more than you'll know actually) but that is one of the sexiest things I've ever seen on a Rover.

Alum tank

I make marine fuel tanks occasionally, what you do is just weld on a thicker alum ring where the sender screws into, easy and leak free. You can drill and tap it before you weld it on, and if you weld the inside of the ring to the tank you don't have to worry about the screw threads leaking.

I totally dig that tank! Did you install baffles in the tank, or does the cut away kinda act like a baffle?

[onecross]

sorry for the hijack amcordo.

Thanks complements and advice on the tank i will be sure to make improvements when i make some more... we put the tank together last minute so that's the reason i didn't have time to make its better.

Thanks, yes there is a baffle similar to the original one works great!

cheers!

109 tank

i want one, please?

[amcordo]

BINGO!

Later year 110s have plastic fuel tanks. I bet I can make one fit just fine.

I don't know for sure, but I think you're being a bit optomistic on the fit of that plastic tank. AND, for $400, I think I'd just have a welder do up the correct tank in aluminum or stainless.

Does the 110 have that crossmember back there like the 109?...You know, the one that causes the 109 rear tank to be "U" shaped. I really don't know. Let me try to scare up some photos of a 110 chassis with that tank installed...

[SafeAirOne]

You might compare the location of that 2nd crossmember on the 110 and on the 109. I can't see how you could make that plastic tank work with any degree of grace:

Maybe move the crossmember? then you could put any # of different tanks back there...
