Holley Sniper EFI Tank Installation

Has anyone had any problems installing the Tanks Inc 16 gallon EFI fuel tank in a 1965 ? The problem I’m having is that I can’t get my filler neck back in. It’s about a half inch shy because of the filler neck on the tank itself is 2 inches. I contacted Holley and Tanks Inc, they both suggested that I cut my filler neck down to fix the problem. I don’t think that’s right. I’m open to suggestions. Here’s a few pics to show what I’m talking about.

Cut the filler neck, then you can install a flapper so that gas doesn't slosh out.

I had to cut the filler neck on mine and use the included hard rubber hose to bridge the gap.

Thanks. It’s just that Holley and Tanks basically said that I’m the only one that’s had a problem out of the hundreds or thousands that they’ve sold. It seems that they could include a shorter filler neck with the kit, to save modifying the existing one.

BTW, that comment above on installing the flapper deal is worth it's weight in gold! One of the dumbest least thought about mods I've done to my car that is absolutely amazing evertime I hit the gas pump! Pull it full blast, click the dealio on the handle and let go and stand around checking out the chicks in the car across the way while you fill up without spilling a drop when it clicks off!

What is this flapper deal you speak of?

BTW I never, ever look at attractive women. I need this because I get so in to Gas Station TV.

I think there's a thread on here somewhere explaining. Pretty much cut the flap section out and weld it to your filler.

HA! That’s funny. You’ll read about me on Yahoo News, “ Moron tries to weld gas tank, blows up neighborhood”. Later in the hospital I would realize that I could have taken the filler neck out.

I may keep this in mind for when I convert to fuel injection though. Thanks!

Update. I’m having a shop cut 1/2 inch out of the filler neck and weld the end back on which will keep the lip for the clamp. Thanks for your input.

Just as well have them at least weld in something like this. It'll make filling it a less messy affair.

Sure your problem is fixed, but wanted to mention my filler neck has a rubber hose on the neck and other end on the tank thats clamp down by hose clamps. That seems to be what your missing in the image or perhaps been a solution?

Actually looking at the pic again I see it's just to long not short. Anyone else with this problem just cut it. It's a cheap part to replace

Been a few days since I've been on here so better late than never... Like said above, I think I saw the thread with the info on a different forum somewhere. Somebody here messaged me a link to a thread with the info. I was going to make my own as I'm more than capable of cutting it and welding in the flapper but there was a guy on the other forum that was selling repop filler necks that he was putting the flapper deal into. I just took the lazy route and sent him my cash and did a quick simple install.

It's a mod that I literally forget about, until I'm at the gas pump and then I love it And yeah, you're right It's all about that time watching the gas pump TV for sure I definitely would never check out the vegas strippers hitting the gas pump on their way into work Blasphemy LOL

Found it, here's the thread that led me down that rabbit hole that I have zero regret of diving into
