Fuel Tank Crossover Pipe

I haven't posted in awhile but figured I'd share the wealth with what I built. There used to be an aftermarket one in the 80s and I've built a couple of these for my trucks over the years and each time I improve a little. So here ya go.

This allows you to fill both tanks at the same time from either side of the truck. Instead of trying to market and sell them I decided to just give out instructions and pictures of how to build your own. This way I am not responsible for anything on your vehicle should you choose to undertake this endeavor. Besides I have gotten plenty of help over the years from the truck community and it's always great to give back. The reason they are split in the middle is a couple reasons. 1. It provides flexibility and 2. You can install and remove both sides without pulling the bed.

List of parts.

1. At least 72" inches of 2" Stainless tubing. If you don't use stainless you risk the insides rusting and getting in your fuel. 1.75 would probably work as well but I wanted 2" to make sure I had enough room for air as well as fuel.

2. Gates 23972 fuel filler hose. Comes in a 3 ft section. You will need to cut 5 couplers out of it 3.5" in length. If you want the tube a little closer to the frame cut 2 of them a little shorter depending on where you want your tube. Those will be your connections between the tank and the tube.

3. 10 2" hose clamps.

Instructions. Hope you can follow along with my brain and lack of phone typing skills. LOL. If not maybe pics will be better than my instructions.

1. Cut 2 30" sections off your 72" pipe. Cut the remaining section in half.

2. Measure 24 inches from the 2 30" sections and Mark it. Measure the inside diameter of the pipe you have and drill a hole with a hole saw to match at the 24" mark.

3. Using the 2 shorter sections notch one end of each to match up to your 30" pipe. There are lots of ways to make tubing notches. YouTube is your friend.

4. Weld the two pieces together to make your T-fitting.

5. Cut both of the shorter pieces to 2.25" from the inside of the long pipe.

6. Put everything together.

7. Depending on how level your setup is I made a couple stands and bolted them to the crossmember and then welded them to the tube level. I can give you measurements but most will be different I'm sure depending on where you put them.

Best of luck everyone. Hope this helps a few people and your welds are better looking than mine. Lol.

Re: Fuel Tank Crossover Pipe

How well does it work with the Auto-Shutoff nozzles?

Gates Fuel Filler Neck Hose is the good stuff. It meets the SAE J30R6 Fuel Filler Hose spec.

Only time I had an issue with the last ones was on a hill toward me. But I didn't have the pipes level with the middle stands either. Even then though I just flipped nozel upside down and didn't have an issue. I plan on making a video after I get the truck back together when I go to fill it up.

Re: Fuel Tank Crossover Pipe

Great Idea!!
I had a 78 with dual tanks.
That would have come in handy.
I am tuned in for the video.

Re: Fuel Tank Crossover Pipe

TRADERS Trucks carried that cross over kit, almost ordered one for my 83, glad I didn't, read later on that the parts used were cheap and prone to leaking.
