Leaky Fuel Fill Hose... What Have Members Done to fix?

I bought a fuel fill hose from BJs a few years back. Now, it is all cracked and leaks when filling, or if tank (Poly replacement 19 gal) has more than 14 gallons in it. Also leaks with lower fuel level when on a side hill.

Leak drips on hot exhaust pipe

Is there a better product that does not get affected by the ethanol in our fuel?

What have people done to fix it? I'd hate to replace every 2-3 years, because the job is a PITA haha.

Cheers!

Is the entire hose cracking or is it just cracking around the hose clamps?

Cracking is not just limited to the area around the hose clamps. I have an S shaped section (exhaust pipe from muffler shop) that the fill hose clamps on to, then a short 3" straight run of heavy duty fuel hose between that and the tank. The heavy duty hose is still like new.

It would be nice if there were a plastic or metal product that would eliminate the need for the soft rubber fill hose neck.

Maybe you could give this a try!?

Or make another piece with elbow from a muffler and a short piece of hose to connect the filler piece with you S shaped piece!
(Don't forget the fuel tank ventilation connection)

The problem with the overall design is that when full, the fuel sits in the bottom of the filler hose, causing a leak. As the level drops, side hill and down hill attitudes slosh the fuel, causing it to leak until level is significantly lower (like when parked). Of course, none of this was happening for the 1st 2 years after it was replaced, but over time the ethanol in the gas dried and cracked the fill hose.

Thanks for the Link Heep! IDK if they would fit, it looks like the angles are too shallow. My '76 has a hard fill neck so I know they made them in the past.

I've been dealing with the issue by only filling the tank half way... which only gives me about an 80 mile range

Whatever is used needs to be rated for fuel, and I doubt a coolant hose would be.

Just a few years? Man, whatever material they used to make that hose didn't sound fuel rated. Have you looked into TGW's offerings? Not sure how good they are, but I know most of the stuff I buy from them is high quality:

This is the same as MysticRob posted,
https://www.ebay.com/itm/37144634426...AOSwDftbmcw s

Don't know about TGW , there is a thread about them with taking years before they sending out parts and people have to wait forever before they get what they ordered!

I have never ordered parts from them , but would not taking a chance and find out the hard way!
Their website shows a lot of good parts thought!

Just call TGW and ask if they have it in stock. I've never personally had an issue with them, and I've ordered A LOT of stuff from them over the last 2 years.

On the other hand I've been waiting since 7/24 for a hood release cable assembly from BJ's and been told multiple times now "it'll be here in a couple/few weeks". It's ~$25 cheaper (free shipping) than the TGW one, but at this point I'm close to canceling the BJ's order and getting the in-stock version from TGW just to get it done. Not to disparage BJ's either, as this is the first and only order problem I've ever had with them, and I'll blame this snafu more on the scamdemic and global shipping supply problems. BTW, screw China.

Yes just a few years. might try to use the 2nd plastic fill neck from Old Ironsides, although it was on the right side of the bed. Then have a muffler shop bend what is needed and connect with the industrial hose I got that was $50/foot! It's about 3/8" thick and looks like something you'd see on a fuel truck at the airport.

I've ordered once before from TGW, and had no problem. Good suggestion Rob, I may look into that. It would be nice to have the job done in a few hours, not weeks of down time haha.

Coolant hose (radiator hoses, heater hoses) will soften and delaminate when exposed to motor oil, much less gasoline. BTDT. You need fuel rated hose.

Both Gates and Goodyear sell fuel rated hose in these large diameters, including corrugated flexible hose, standard shapes (elbows) and straight lengths. Search online and you will find them. Your local parts store can buy this stuff, or ask at a marine parts supply. Won't be cheap ...

RockAuto sells some of these hoses, as well as large diameter generic fuel hose (like the 1/2" hose you may need for the air cleaner and PCV connection). https://www.rockauto.com/en/tools/ho...r+hose,1001643 I have bought hose from them cheaply on clearance, and also quality Gates fuel hose in lengths. Their stock comes and goes, and often the quantities required prohibit purchase by individuals. Worth a look occasionally.

MTS almost certainly supplies plastic tanks and related parts to both BJ's and TGW. http://www.mtscompany.com/J-truck.htm I would contact them long before I considered TGW.

I would venture a guess the hose you bought and now leaking isn't truely fuel rated?
I suspect the tgw hose may not be either and you'll just be back to a leaker in a few years.
Whatever they use these days for hose is a poor excuse compared to originals that lasted decades.

If it were me I would make or have made a metal one.
Any good exhaust shop can whip one up.

I bought a replacement filler hose for my grand wagoneer, in a few years is was all cracked and dryrotted. Same with many many other "rubber" hoses/parts I have purchased. Whatever they use nowadays just does not last like it used to.

This also applies to the 1/4" - 5/16" - 3/8" standard fuel hose you can buy today. The generic stuff they sell at Autozone and Pep Boys is c**p. Lasts a year, tops. Suggest you buy name-branded fuel hose, and check it annually. I buy Gates hose 10' at a time from RockAuto and it seems to last well enough.

Thanks guys! I'm leaning towards trying to use the plastic filler neck from Old Ironsides, then a quality rubber piece (such as Goodyear) to connect it. I'd like to be able to use the top 1/3 of tank volume
