Bringing up Stepside gas filler hose again

[chrismoore701]

Getting ready to buy my stepside gas filler hose. I found one at Classic industries for $22 or so. I have dual tanks and planned to buy two and cut one up and twist it to work for the other side. Does any one have any other ideas how to handle this?

Thanks

What year is your truck? Also, let me know if it works!

1979

What else have you guys done to the hose on the second tank to get it to fit?

[chrismoore701]

Why not just get a radiator hose to fit?

Radiator hose is no good. The gas will deteriorate the hose. They are made differently.

[chrismoore701]

What about something like this. There are multiples sizes

I think that you could use exhaust tubing for the bends, and connect it with the hose that is in that ebay ad you posted.

If you search online you can find semi flexible fuel filler hoses of different diameters. Some of the hoses have a wire molded into the core to allow it to be bent and keep its shape (somewhat.) Look for flexible fuel filler hose. Don't use radiator hose - it is not designed for fuel. Race cars and cab and chassis utility trucks often use this hose.

One problem with using a flexible hose, is the factory hose is a different diameter on each end. I'm not sure if all year models were like that. I know mine was.

[chrismoore701]

I did a quick check on the diameter and they seem to be the same, but I need to look a little closer before I order. That stuff on ebay is like $0.99 per inch, not a bad price.

[chrismoore701]

Did a little research and it is a little scary how bad it is to use radiator hose. I measured the od on tank and neck. And they are both 1 3/8". So I am good there. I just need to put it together and measure. Will keep you posted

I do not trust the aftermarket stuff so I looked until I found a New Old Stock Factory step side hose for my truck. It's far better than some of the weird rigged up ones I have seen

I cobbled mine together using a section of radiator hose, it was supposed to be temporary. But that was around 5 years ago now and it's still holding up great, other than hardening up some. I thought it would be lucky to make it a year but I was wrong.

Hopefully someone repops correct hoses soon.

The flexible fuel line with a wire core will bend and keep a set very well. Most if not all cab and chassis trucks with utility boxes use this hose to connect to the fuel filler openings on the sides of the box.

[chrismoore701]

Having a hard time finding 1 3/8" flex hose. Any idea where to get it?

I would contact vendors to make sure that the hose you select will make a sharp enough bend to accommodate your application. The ones I have seen are very strong so it will take some muscle to make a sharp bend.

Also, if you have a local pick and pull junkyard with commercial utility body trucks in stock, you may be able to get a useable hose for a few dollars.

You can get 45 degree and 90 degree and 22 1/2 degree bends (I think) from Gates if you can approximate the bend you need. I used these on the dump box conversion on my 83. The hoses are very long and you just cut off what you don't need. With those 3 angle options, you can turn the sections of two hoses at different angles and join them with a short piece of filler pipe with large hose clamps. (Think plumbing fittings put together to fit a close quarter bend.) This will likely be cheaper (check Gates filler hoses on Amazon or Orielly Auto Parts) and you will get a smoother transition from tank to filler neck. You can find 1 3/8" filler necks and various angle filler hoses at the junkyard, so with some creative fiddling you can also get what you need that way.

I stopped by a hydraulic hose shop today. And they said to never get a hose with a steel coil in it as it will conduct static electricity and cause a fire. Just an FYI

You just made me feel better about my crappy radiator hose as a filler hose.

[Pontiac1976]

I think LMC has filler neck hose ARE they any good ?
If you do have duel tanks do you not just buy two turn the hose around to fit the other side.?

[chrismoore701]

I am going to go to a local hose shop and see what they offer first. I think I found them at classic industries.

[chrismoore701]

What about using some exhaust bends with straight hose? I know I don't want metel in there but this is not complete connection

[wildwilly4x4]

static wont build up if you have it all grounded. That's why there are ground straps to the filler neck. If it couldn't be metal, then the tanks wouldn't be made of metal. Think about whats going on with your filler system...

[chrismoore701]

Yes I know about the gas tank being metal, but I thought you want the tank isolated from the filler neck with a rubber hose, hence no grounding strap

[wildwilly4x4]

No, rubber hose is there because your tank is mounted to the frame, and the filler is mounted to the body....allows for movement.

When you run a hydrocarbon through a rubber hose with no ground, static begins to build up as it flows. when you fill up with gas at the pump, static is building as the flow goes through the hose. Once the charge gets to the filler nozzle, if the nozzle isn't in good connection with your filler neck, a spark can jump from the nozzle to your trucks filler neck, potentially causing a fire.

Metal in your filler hose will be fine, just make sure you have a good ground at your tank, and at your filler neck.
