Dual Tank Filler Question. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

monte0185 · 11-25-2013, 05:01 PM

Has anyone ever seen the fillers for dual tanks connected together? I was up under my dually on the passenger side working on my drop and There is a pipe that connects to the filler and the tank and also looks like it runs to the drivers side but I didnt get over that far cause truck wasnt up that high and it was cold. Just curious if anyone has ever seen this?

I had a dually that had the same. It was home made, I believe. It filled on the drivers and had a pipe(iron) running from drivers to pass side. That was it very crude.

It was a parts truck that I got to see if it worked.

Mine seems pretty crude also and probably home made. Im gonna pull the bed off and take some pics and probably replace with some aluminum pipe. Outside looks real rusty I havent tried to look inside yet. LOL. I have filled both tanks and depending on the angle of the nozzle it can be a pain to fill. Didnt realize it may be crossing over till i was looking under the truck and seen the tube.

I have seen it on a 1/2 or 3/4 ton, I don't remember exactly but it was definitely homemade and not skillfully.

Yep thats it. Well the big tube looks correct anyway. Mines a bit more rusty though. Lol

Well I answered my question on the tank filler!! Here ya go guys!! Not sure if I want to put it back or not..

walkerb · 12-01-2013, 03:38 PM

How does the pass side tank vent? The only think I would be worried about is the scaling and rust deposits from the metal pipe in the tanks?

monte0185 · 12-01-2013, 03:48 PM

They both vent thru the filler necks like stock. I was worried about rust also so im doimg away with it. Im gonna take it to an aluminum welder and have him make me one. Then ill put it back.

That type of set up is the biggest PIA to get the second tank filled. I had one on a J10. The "main" tank has to fill completely. Then you continue and fuel is pushed into the second tank. If you are lucky, you can get about a gallon a minute into the second tank. I ended up yanking it and setting up a separate fill for the second tank.

Anyone know where I can get the rubber filler hoses to fill the tanks individually now?

I like it! Thought about doing that same thing on my old C20. It may take longer to fill, but sure beats driving around to another gas pump to fill "the other tank"! I did a few long trips and would alternate filling one tank full, then drive till the other is empty. I miss my old truck!!!!

To answer about getting new rubber hoses, any of the truck companies should have those. I LOVE the LMC catalogs, it's like having an IPC (illustrated parts catalog) for my truck. LMC definately has them.

I dug around and LMC was the only source I could find that had them. 50$ shipped for both sides. I will probably put it back at some point but Im going to have someone make me an aluminum or stainless one first. This one was rusted inside and out. It would be alot better if someone were to take the time to move the filler necks up higher on the bed. It would fill alot easier then and work much better. My main concern other than the rust was the rubber joint in the middle being right over the exhaust. I could just see my truck burning down from that.
