The Stovebolt Site Forums The Shop Area General Truck Talk Filler Neck - Radiator Hose???

Probably been down this road before᠁ here goes-

Is it acceptable to use radiator hose as a filler neck for a gas tank?
A search yields varying opinions. Some say “shouldn’t but can᠁” , others say it will break down in short order. I tend to think it would be ok , but I trust this information pool.

What say you?

Why would you want to? I wouldn't use it. Buy the dedicated filler tube material or one of the ready made ones.

The why is simple - impatience.
(At least I’m honest᠁)
I’ve been working on my truck daily for weeks now , hoping to roll out early April when the salt trucks are done for the year. Snow coming tomorrow btw, streets painted with brine.
Today was gas tank install day. I naively thought I could buy suitable hose for a filler neck locally; don’t know how I got that into my head but I did. The only thing I could find with the right i.d. was radiator hose. Right after the gas tank install comes starting the engine- with the new intake manifold! - and timing the ignition. (high rise single plane manifold swapped out for dual plane, 4 bbl Edelbrock on top)

I’m realllyyyy eager to see and hear my 283 running with that new intake; been a long while in the making.

There’s my explanation.

Why cheap out now...order the correct fuel rated hose today and you'll have it before the snow melts...

I ordered my filler hose and vent hose from NPD. Everybody sells them. You'll have it in a few days.

Even Rock Auto sells the whole shebang in a kit - cap, grommet, hoses, clamps, and filler neck

I want to hear that thing run too, put 5 gallons in the new tank and cap the steel tube with a plastic cap from a rattle can, a little duct tape to hold it in place but let some air in the tank. We might get 2 - 4 inches of powdered sunshine here but the county isn't prepping the roads yet.

Well ᠁ alright then.
I found a good option on Amazon, clamps included, quick delivery. I can pre-fit the plumbing under the truck in the meantime - I have what I need to install the valve and flexible hose section as per earlier discussion.

Snowing pretty good here anyway. Got in a couple rounds of golf last week, beautiful weather; now it’s winter again.

Anyone have use for a cut up radiator hose?

Good to know you have one on the way. I'm excited for you to have a better induction system and hopefully with help from your buddy you can fine tune the Edelbrock. Heavy snow here right now with 2 - 3 on the ground in the last 3 hours.

Snow –-
The key is to find advantage in adversity.
If it were still 70 & sunny like last week I’d have a lot of angst about my truck not being ready to roll out of the shop.
As it is I’ll just continue to enjoy my excellent winter accommodations and truck working situation.

The flatbed truck I just bought has two brand new fuel tanks inboard of the frame rails and 3 feet of flexible radiator hoses connecting them to the filler caps in the side of the bed- - - -they leak like the Titanic! Gonna replace most of that setup with steel exhaust pipe tubing and SHORT nipples of gas filler hose to splice them together.

Not too shabby!

Yeah , it’s a nice winter spot.
I’m alongside a Huckins powerboat, about 40 ft and built in the ‘50’s by a builder of PT boats in WWII.
There’s also a 1961 Chris Craft runabout under renovation, and that yellow boat on the hoist is a Donzi project.
Then , of course, there’s a ‘54 3100 with ‘67 Camaro front stub and drive train , adding to the eclectic cool factor.

I found both the filler and vent hoses locally. One at NAPA and the other at O'Reilly. It wasn't cheap though. You might check again.
Radiator hose isn't fuel rated, and will eventually start leaking.

Cool factor both for boats and the truck. Nice digs.

Waveski ... Is the Chris-Craft a Sea skiff, by any chance? Looks like one ... I've had a life-long love of those since I was a kid growing up in my parents' marina. We had a lot of customers who owned them and we did pretty good business with them (Restorations, maintenance, storage, etc) and the older pre-war Chris-Craft's. Love those boats!

It may be a Sea Skiff, the bigger ones had the headlights like the one in my picture. I’ll verify next time I’m there.

Back to truck stuff before the alarm trips–-
I have ordered good quality 1 3/8” id gas line as shown a couple of posts back. The 1/2” vent I’ll get locally.

Looks like a late 70's 18' Donzi...

Nice to have the truck inside for the winter!

Sea Skiff confirmed, 1961 , 23 ft.
Good mahogany and bronze in abundance.

Now to offset that off-topic content, I will be in that boat shed today, under my truck, cutting steel fuel line and plumbing my new gas tank .

I sold my 34 ft sailboat 2 years ago, couldn’t bear the responsibility and maintenance any longer. It was stored off season in the same building. The loss of that boat left a huge void in me ; that void is largely (but not quite entirely) filled by my hot rod. It is a source of great enjoyment to be back in that shed, surrounded by boats , while turning wrenches on my ‘54 Chevy pickup.
Best of both worlds, counting my blessings.

Don't forget the vent hose on the filler neck. It needs to be fuel hose , too.

Acknowledged.
Readily available in local hardware store.

Filler neck hose arrived yesterday. That fact alone does not warrant a post- I’m posting because I have 18” of good quality filler neck but only need about 5”.
If anyone needs filler neck hose for a tank behind the seat let me know ; I could free up a second section and still have a spare.

Waveski, sounds like something you could offer in the Swap Meet forums
