Leaking Fuel Return Hose

[todds112]

I think I need the rubber fuel return hose that goes from the fuel filters down to the frame and connects to the copper line.

It's leaking pretty good. I took the lower connection apart, cleaned and put it back together, but it still leaks. I can't tell for sure where it's leaking from. It doesn't leak when it sits and idles, but if I drive it, there is fuel all over the area of the connection. There will be fuel above the connection and leaking down dripping off the connection itself. I'm assuming it's spraying somewhat.

I have found listings for the input rubber hose, but haven't found the hose I think I need. Is this part available, or can an auto parts place make one up?

Should have thought of this first. I pulled the metal tag and it has the part number: 10896242. Found one on an auction site for $12. It's on the way.

I had the input hose leaking a little while back. Glad you found a hose at a good price.

Looks like my input hose was replaced already. Hope this fixes the leak. Hate to lose even drops of $4/gal diesel!

Got the replacement hose today and installed it. Wow the old one was really bad! Can't believe it wasn't gushing out even at idle!

For future reference you can use Pushlok and make pretty much any hose you need. Any good hydraulic hose shop carries the stuff.

Or just have the hose shop make you one.

Thanks, I have to say I am pretty confused by all the different types of connectors and what is compatible with what. Flares, nuts, feruls, oh my!

The closest city with stuff like that is a several hour round trip for me. It would be nice to be able to have some connectors and hose on hand for repairs like this when they come up.

most stuff on these trucks is easy to get fittings for even online. The beauty of pushlok is you can build a little stock of common jic fittings and make hoses in seconds as you need them.

My fuel return hose looks just like this. Further inspection shows the lower section to be "sweating" thru all the cracks even while idling. The fitting appears to be OK.

The larger concern that I have is that for it to leak so much, the pressure of the return line must be substantial, and I thought it shouldn't be. It just runs another 8 feet or so and back into the tank.
Is the fuel return high flow? Should I be concerned that something is causing too much back pressure in the return?

Regardless, I plan on replacing the whole return line (and switch to 3 stage spin on) in the near future in a manner similar to Rustystud

Not to bring up up the past, but I have the same problem of this hose 'sweating' fuel. I can only find the hose from 2 places, Big Mikes Motor Pool, and Eastern Surplus (as part of a set). Both seem a bit pricey to me, and Eastern lists the condition as NOS - I'm not paying top dollar for 40 year old rubber. Anybody know a lower cost source for these? I looked at Memphis and Saturn but couldn't find anything.

Saw pushlok was suggested, but not familiar with them or making my own hoses (I don't have any press/crimp tools).

Thanks all.

Do you have a hydraulic shop or a hose shop near you? I had one made locally. It was only $30 or so.

I second welldigger's advice. A local truck/hydraulic shop had no problem cutting the old fittings out for re-use (or had new fittings on hand, I don't remember). New hose for chump change.

Look for NAPA or Goodyear Rubber, they both will have the facility to make up your hose. Also check farm equipment shops....

I think in the previous posts they are suggesting Parker push lock hose, we used to use it for lots of things in a plant where I worked, great stuff. As long as you use their hose and fittings it just pushes, although not real easily onto barbed fittings, IIRC it holds 250 psi . I have lots of 1/4 and 3/8" air hose that's 20+ yrs old made of this with zero cracks and still very flexible, aero quip and others also have a equivalent hose/fittings. My winch truck was apparently overhauled at Toole (spelling?) , has decals on oil filter cans and "overhauled at TEAD" tags, it has a pushlock hose that was painted when the engine was at overhaul, this hose comes from a port in the side of the block just below the air compressor and goes to the IP I believe, oil line?
