One of those little rubber lines cracked while my wife was driving. I think it dumped half a tank of fuel on just a short trip to/from the emissions place. Anyway, any recommendations on what to use for replacement hose? Just generic stuff from the parts store (3/16", 1/8" ?) or something more specific? I read that some kinds of hose don't require clamps, which would simplify install...

I don't know what to tell you, I have a few sets I pulled from engines I parted out but I know you can't just use generic hose, you need to get the diesel hose.
I believe that the automotive stores have them in kits with everything you need
 
I used Tygon fuel line I got from a small engine repair shop--it is good stuff and no clamps were needed,you just push it on and it will not come back off the barb fitting,you must cut it off !..

I replaced a few on my 6.2 at least 3 years ago and its still intact..I got 1/8" intended for weed eaters and the guy cut off 5 feet from a bulk spool and only charged me $5..I keep the leftover line in the glove compartment in case another one fails..

My '85 Suburban came with the AC-Delco factory replacement hoses,so far I haven't used them,they were the black rubber OEM ones that need those teeny clamps,that SUCK to install on the rear most injectors ,which was the one that failed on my pickup..

I also got a few feet of Firestone air brake tubing, 1/8" ID that a local diesel shop gave me when I asked them what they used--that stuff is stiff and has to be softened up with a flame before it'll go on the barb fitting,I did use that to replace the rear most line on the Suburban--it worked OK,but I like the Tygon a lot better..
 
That's the stuff,but I'd avoid any made in China...guy at the mower shop said he got burned buying the cheap stuff,it'll get hard and brittle and snap easy in short order..

You think the stuff I linked is Chinese? I can't tell. It says "genuine"...
 
Cant tell,Amazon sells stuff from all over the world..
"Genuine" may just mean "genuine Chineese made "..

You can buy Tygon at places like Lowes and Home Depot in the lawn mower section,if you need it quick...or any mower repair shop..

Oh yeah--got an E-mail from Home Depot,they are now going to close at 6pm starting today around here..."to allow employees to re-stock and clean the stores"..
The Lowe's near me is just about empty of customers every time I go in there--last time was about 3 weeks ago..makes me wonder how long they'll stay open,period..

Buy a $20 hose kit from Badger Diesel:

https://www.amazon.com/6-2L-Diesel-Injector-Return-Chevy/dp/B079H5XCZ9

(It's sometimes cheaper on Ebay). They'll throw in caps and give you a fair amount of extra hose in case you mess one up or you want to replace the center hard line.

Avoid cheap vendors, replacing "brand new" failed return lines is a sucky job. Ask me how I know. :doah:

I have also used normal fuel line without issue. But the stretchy stuff that doesn't require clamps is worth the extra few dollars. And change 'em all out while you're at it. It's cheap insurance, much cheaper than dumping fuel on the ground.
 
I've found a whole roll of it on ebay for cheap.

Can't remember the link at the moment.
 
If your talking about the return lines I believe you can purchase a complete kit from any auto parts store or quad tuning and dont require clamps.
 
Dorman does have a kit available,but I've heard the hoses suck and leak in short order..
I'll use only Tygon on my 6.2's,it is so much easier to install and will last at least 3+ years..it stands up to diesel well,2 stroke gas & oil mix is more destructive and it will eventually harden and crack on that application..
I've had to replace the fuel hoses on my weed whacker and chain saws every 2-3 years due to ethanol hardening it ,it gets brittle..my punishment for not draining all the fuel out before storing them..

I had the rubber cap on the rear most injector fail too,I just used a 1" piece of the Tygon hose with a machine screw threaded into the open end to make a block off plug..I tried one of those "vacuum caps" they sell in "HELP" brand,in two days it got so mushy it started leaking like crazy,it was like bubble gum--so don't use those!..
 
Another plug for the badger diesel kit linked in post #8. I have up to 4 of these engines on the road any given day. Each truck has a ziplock bag with one of these kits in it. You never know.

Plus, the stock little bitty squeeze clamps really annoy me and I love the push on aspect.
 
Yup, I ordered that one. I fixed the busted segment in the meantime just by cutting the broken end off and putting it back, since it had enough slack. Those little clamps are a huge PITA, even to remove. I just demolished them with needle nose to get them off. Not sure what tool could grab all three little prongs at once and fit into that small space.

Needle nose was the best tool I found, when I was changing and reinstalling those clamps.

But today I would not bother with clamps. Stretchy rubber is more betterer.
 
Maybe one of these would work--if you have the hands of a heart surgeon ..and the eyes of a hawk..duckbilled heimostats.jpg wide duckbilled heimostats.jpg

Me,I'll stick with Tygon..push it on,done!..
