Here's a video that shows the filler neck on my truck.

This is a blank filler neck that fills the hole left behind in the cab when the stock tank is eliminated, allowing you to retain the original look, and avoids the need to patch and repaint the cab. The parts have been sprayed with two-part satin black paint.

Included in the kit:

-Filler neck, shortened, 2-1/4" diameter
-Clamping Plate
-Cab grommet, 67-70 style (fits 71-72 cabs as well), made in USA
-Pan-head screws for clamping plate
-Pan-head screws for increased clamping (not usually necessary)

Installation instructions can be found here.

Note: you will need to provide your own 67-70 non-EEC gas cap, such as Stant 10623 available at O'Reilly for $9. I got my cap from GMCPauls. EDIT - Member D.B successfully used an OE 71-72 grommet with his dummy filler neck. EDIT2 - 71-72 caps do work after all.

As an option, the clamping plate is designed to have an AC power outlet connected to it for people who have an inverter in their truck and want a convenient way to plug external items into it. It's designed to work with Journeyman Pro HJP-5279 (not included). In order to install the outlet, a blanking plug must be removed from the clamping plate (drilling required), and the two mounting holes must be tapped to #8-32. Also, the four clamping plate screw holes must have 100° countersinks added so that 100° flat head screws can be used (not provided). Instructions can be found here.

Overall, I am pleased with the way these dummy filler necks turned out, and I am picky. Please note though that there are some minor cosmetic flaws such as small lumps from the brazing done on the original filler necks I purchased. Some of the welds inside the filler neck are not as clean as others, but the welds are completely hidden inside and are fully functional. There are a few very minor thin spots in the paint as well as the occasional slight orange peel, but the portion that shows from the outside of the truck is very nice. It isn't possible to get complete paint coverage on the inside of the filler neck due to the shape of the opening.

Also, please note that I tested the design on my truck, and it fit quite well. There could be variations from one truck to the next that might influence how snugly the dummy filler neck fits in the grommet. Included are four jacking screws that will allow the fit to be tightened up, if necessary.

I'm replying to the thread so it's easier for me to find again later. 😁

I need to replace my entire cab, so once I get that handled and off to get cleaned up, I'll be looking to add this to the build. 😁

Great work, man!

Sounds good. I sent you a private message.

Here are some photos that were sent to me by member Yeller_71 of his truck that spent its first 50 years in California. He installed a dummy filler neck on it to preserve its really nicely aged paint. Nice truck!

[YBNORML]

Love these, would like one if you have any available. Feel free to send me a PM

Thanks

[Wilkinson_LSX]

If you can add me to the waiting list please, id like to grab one of these off you.

Thanks

[Wilkinson_LSX]

Awesome, thank you

Here are some photos from Travis who installed a dummy filler neck today.

[Chevylife]

May I be added to the list for neck when they are ready ? Thanks

[pjmoreland]

Nice! Thanks for posting the photo. Cool truck. I think the rear fuel tank installation might take a little longer than it took to install the filler neck.

I'm working on another batch of dummy filler necks. They should be ready in about a week.

Here's a really cool idea from Glenn who bought one of my dummy filler necks recently and converted it into a kill switch that is activated by twisting the gas cap. Here's how he did it:

"The red cap comes off. I put a 10/24 nutsert on the cap, tapped an aluminum rod, screwed in and red lock tight a piece of all thread to the cap. Cross drilled the other end and inserted a 1/8” steel rod to turn the switch."
