Anyone running 3 fuel tanks in an M1010 or other CUCV?

Hey all,

I got got a deal on the passenger saddle tank and a 30g suburban tank.
anyone running all of these?
I’m trying to wrap my head around the plumbing and wiring of it all.
I’m know It’s a bit ridiculous but I am thinking long range expedition use.

Any input is appreciated

thanks a bunch

it would be hard to get 3 filler necks and doors, you may be able to put a transfer pump in to fill the 30 gallon tank. The other problem may be the fuel switch. i don't know of a three way but you could use two -two way switches in series to get to the third tank.

It will be a lot of weight in fuel

just my thoughts. I want to upgrade my 1009 to a 30 gallon one of these days

Well, I was going along the same thoughts...I have mocked up the passenger side and I think can get the filler just over the horizontal rib but between the wheel well and the cold air intake for the heater and wired “factory” with the switch....I like the idea of making the rear tank a transfer tank.....I’ll mock that one up and see where the filler could go.

Thanks

On the M1010, I think it would be difficult to mount the suburban tank unless your willing to lose the rear entry ladder.

Dunno about the 1010 but my 1031 wouldn't fit the sub tank unless I moved the rear crossmember aft and changed the bumper bracing. Yes re: transfer tank - but try this version. Make the rear the main tank and transfer into it from either or both saddles (use the blackout service light switch to control two pumps and switch between tank senders to a small gm squarebody fuel gauge mounted in one of the upper idiot light locations - add an idiot light elsewhere on the under dash metalwork if desired)

Plumbing: send me a PM and I'll send pics of my system. I mounted the filters/pumps/1-way valves and a drain valve for the system under/inside the transfer case crossmember.

Skysix great idea having the rear main tank as the primary is an outstanding idea.
I’m Finishing my “kitchen” this weekend in the 1010. I’ll mock everything up next weekend and see how she goes.
I’ll let you know how it goes.

thanks a bunch

I'm confused. Why is making the rear main tank a great idea? What is the benefit of that? I'm in the process of adding a passenger side tank into my M1010 and have thought of a third tank in the spare tire space, especially since the spare (which is larger than stock) does not fit there very well anymore. I may just put a water tank in that location but I want to hear of the benefits of using it for a main tank....?

My guess, you wouldn't need to plumb a filler neck for the rear tank. If you use your side tank(s) to transfer fuel into the rear one, you can keep the stock fill on the driver side and just fill up that tank, after you transfer fuel to the rear tank. Not a bad idea.... That might solve my using with the rear tank setup I am trying to use....

I did not think of that. Not bad. I'm about to pull the plug on a tank/hanger/sender unit and valve for mine and I guess I should rethink it a bit before I do.
