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 epoxy 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.

Hey Patrick,Payment has been sent.Thanks for making these. They are really trick. ( I haven’t used that word in awhile, but it really fits.) Dan

Re: Dummy Filler Neck for 67-72 Trucks with Removed In-Cab Tank
 

Haha, thanks, and payment received.

Re: Dummy Filler Neck for 67-72 Trucks with Removed In-Cab Tank
 

Super! Let me send you a PM on info.

Re: Dummy Filler Neck for 67-72 Trucks with Removed In-Cab Tank
 

Patrick looks like another 15 wouldn't hurt. I had to push you for the first run I will motivate you for the second run. The list for a second go around looks good now and it will grow before they are finished. If your only making 11 can you serialize them in case they become collector piece in the future? I think I was lucky number #01 and would like it sent in a nicely hand crafted silk lined box. Lol

Thanks for taking on the project.

Re: Dummy Filler Neck for 67-72 Trucks with Removed In-Cab Tank
 

Ok, cool. I'll add you to the list. Thanks.

Re: Dummy Filler Neck for 67-72 Trucks with Removed In-Cab Tank
 

If you have my name on the list i'll pass and let someone else have it
because i'm not ready right now.

Re: Dummy Filler Neck for 67-72 Trucks with Removed In-Cab Tank
 

Another idea i'm tossing around is hooking it up to the windshield wash bottle. I'm going with a more modern bottle with a pump built into it. Like I said i'm a long ways away right now. Still welding in the floor.

Re: Dummy Filler Neck for 67-72 Trucks with Removed In-Cab Tank
 

Definitely in! Don't really mind if it's in this batch or the next, but can PayPal to secure my spot in line!

Re: Dummy Filler Neck for 67-72 Trucks with Removed In-Cab Tank
 

Thank you. I will hold your place in line without a pre-payment.

Re: Dummy Filler Neck for 67-72 Trucks with Removed In-Cab Tank
 

I only have the hand-made one in post #2 left. It's $100 plus shipping, and does not include a grommet. Do you want that one? I will be making another batch of new ones soon if you'd rather wait.

Re: Dummy Filler Neck for 67-72 Trucks with Removed In-Cab Tank
 

68 C10 Driver wants the hand-made dummy filler neck. PM sent with PayPal instructions. Won't be able to ship until Thursday.

Re: Dummy Filler Neck for 67-72 Trucks with Removed In-Cab Tank
 

Is there a timeline for what I'm guessing is a second batch?

Re: Dummy Filler Neck for 67-72 Trucks with Removed In-Cab Tank
 

Got mine in today. Nicely done! I don’t have a gas cap yet, but it looks excellent so far.

Re: Dummy Filler Neck for 67-72 Trucks with Removed In-Cab Tank
 

I'm really glad to hear it! This has been somewhat stressful for me. Thanks for posting the photos! Your truck looks very nice.
