Custom Fuel Tank Location - Filler & Vent Hoses.

[Mike_82_Shortbox]

Greetings Guys and Gals!

I just got an email from the forum saying it's been a while since I posted, which prompted me to post about my latest problem.

I'm installing a square, center-mount fuel tank from Tanks, Inc. i.e. 1973-81 Chevy Blazer Fuel Injection Gas Tank [<—link].
The tank has a pretty standard EFI fuel pump, and this fuel neck, which came with the tank, but strangely they don't sell on their website:
6 Hole 90 Degree 1-5/8" OD Bolt On Filler Neck w/ 5/8" Vent, Part Number: FN15B [<—link].

Terminating the filler hose at the inlet end is a custom billet filler neck that came with the (1973-87) Hidden Tail Light Fuel Filler Kit [<—link].

This 1-1/2 inch outside diameter fitting has no vent tube fitting incorporated. And even though Tanks Inc. sells a gaggle of hoses, necks, and couplers, there's not a single fitting that will connect two 1-5/8 inch (or 1-1/2 inch) hoses that has an integrated 90° fitting for a 5/8 inch vent line.

Our plan, from tank to filler neck, is to plug a 1-5/8 inch (or 1-1/2 inch) filler hose and 5/8 inch vent hose onto the tank fitting, run those up to a coupler that has an outside diameter of 1-5/8 inches (or 1-1/2 inches), and incorporates a 90°, 5/8 inch fitting for the vent line, and then use a small piece of 1-5/8 to 1-1/2 inch reducing hose (or just 1-1/2 inch hose) to connect the coupler to the filler neck.

We can use all 1-1/2 inch hoses and fittings and just warm up the hose and jam it onto the 1-5/8 inch fitting at the tank, or we can do the reducing system I described above.

Our problem is that no one on the planet makes a 1-5/8 inch (or 1-1/2 inch) outside diameter coupler with a 90° 5/8 inch integrated vent line fitting. How do we solve this? Has no one else ever had this problem in the last hundred years? Certainly we can't be the first ones?

Any ideas?

Yep, make it. Or have it made. It doesn’t have to be a TIG job since it will be hidden. No need to make it super fancy. A good MIG guy will make it just as good. Have him make 10 and put 9 on eBay. You might be famous.

Would love to see this set up when you are done. That tail light set up is really slick. I love hiding all the upgrades in plain sight and making it look stock.

The name of it there in the original message is a link the page, https://classicparts.com/chevy-gmc/...-tail-light-fuel-filler-kit-sku-23-043-driver

All three things are linked in the original message, the hidden taillight set up with the billet filler neck, the fuel tank, which comes with the 90° neck and vent fitting, also linked.

But that was just a link so I could show you the part. Pictures of the actual thing and where he got it are below, in the reply from the actual owner.

Here are some pics of the hidden fuel filler. The kit is made by a company called LSFab https://lsfab.com/
