The time to load up my w200 with more fuel has come. I've already got the in-cab tank (anyone have some clues about the amount this tank holds?) and I'm looking at getting a second tank for under the bed. Anyone know what sort of size I can stuff under there? Can I get a 35 gallon RC tank under her? Either way, I need to start looking for a selector valve. The cheapest I've found thus far is a ford unit from the old ford 250's that came with the dual tanks. Aside from that, I've found one for like 60 bucks. Anyone got any other leads?

Nope no leads on the valve i just go to the closest place that would have 1, the RC tank will fit in the back if you remove the spare tire and it's lift.

Don't you have the spare under the bed and it's little winch like lift you turn and it lowers and raises the tire

What year and model is this...according to your info at the bottom of the post you are driving a multiple year W200/W300..club cab..standard? 
In 1977 the tank behind the seat was 24 gallons and if there was another mounted mid-frame it would be 18-20 gallons.
You should only need a universal 3 port valve like this. Try Checker, NAPA or CarQuest or online.
Niehoff Ignition UN50...online at www.partsamerica.com for $27.99. I also picked one of these up at CarQuest years ago for about $30.

Chump its a multi-yeared vehicle, ultimately a w200, standard cab with the in-cab tank. My guesses were right on the money than about its capacity. I was guestimating 22-24 gallons. What I'm really going for here is as many tanks as possible. I know it sounds rediculous. The RC's came with 35 gallon tanks on the drivers side of the chassis, am I correct? If so, wouldn't it stand to reason that, barring the exhaust work, I could put identical 35 gallon tanks on each side of the underside of the truck? Maybe I'm just reaching here. I wanted to get one of those bed mounted HUGE tanks but it turns out they are illegal to drive on major roads here in NJ so that plan went out the window. Thanks a hell of a lot for your return on the part. The only pieces I could find were the ford one (I'm just adament and will NOT run a FoMoCo piece on my rig) and the other pieces were for EFI, and therefore, pretty damned expensive. Its just that, like my other thread says, I'm going to be driving cross country in June/July and with 60-80 gallons of fuel actually ON the truck, with a perfectly tuned 318 grasping at 15mpg, I might actually only have to stop 2 or three times for fuel. Filling up might take an hour and 200 bucks, but its worth it

·This fuel selector valves aren't brand specific, all the makers used the same ones. The three part numbers in Autozones system are FV1, FV2 and FV3. I can't remember which one corresponds to chumps pic but I think its FV1. The price is about $30 I think. Thats the one you need since you don't have return lines.

duane, thats what I'm shooting for. The tank that gets mounted in the very ass of the truck between the frame rails, then the one that gets mounted on the drivers side, the side saddle type, and then the incab one. I'll need two of those fuel tank selector valves, but it will be well worth it.

Thanks for explaining the multi year vehicle...the reason I ask is it makes a difference when trying to figure out what you have installed as options like the gas tank. During 77 there was a mid frame approx 18 gallon tank installed in trucks...this was part of the dual tank option. The RC used a rear mounted(36 gal) tank that had the filler tube that came out the L/H fender.
The bed (being of different year from the cab) already has a filler hole in the drivers side of the box, right before the rear wheel. Its also got the hose going from the filler down to where the tank used to be. So I've already got that setup. Then I've got the in-cab tank that I will be keeping dispite everyone telling me its no good as if the vent tube gets clogged gas fumes will vent into the cab (I think there was a recall for this as well). So I've got to find the mid frame tank and then I'd like to find myself the RC tank that fits between the frame in the back. Then I've just to go to install the filler tube for it. What is the concensus on finding a matching 18 gallon tank and putting it mid frame under the driver's side? Possible? Feasible?

Try searching www.car-part.com for some used tanks...sounds like you are on the right track. I have found with my Stock 77 W200 I get more fuel vapors from the carb when i shut the engine off than I do from the in cab tank except when overfilling it. In 1977 the standard tank on the truck was the mid frame mounte 18 gal one and the auxillary tank(option) is actaully the in tank cab. Also, have you checked on the R/H fram below the passenger door to see f maybe there is still the facory fuel selector valve installed? Copy these pictures for reference if needed.I need to delete them shortly to make more space available in my files.Hybrid 1ton said:
I have never seen this REAR mounted tank in a truck?
