I have seen people use mini zip ties to hold the lines on also.

Another option is Tygon hose from a chain saw or lawnmower shop.

Most parts stores don't sell the correct sized hose, so I don't agree with a lotta suggestions for improvisation. The correct newer hose is thicker, but its internally barbed so the clamps arn't needed.
From my experience, trying to find small hose clamps at a part store is near impossible as well. They probably have it listed under something specific, and have no where to look.

This is the made in Germany stuff, with sizes on it, in a roll, not the precut junk. It is the same stuff for VW TDI's and Mercedes, so that is probably something to look under at a local part store. 3 5mm Diesel Fuel Injector Return Line Hose Made IN Germany 1 Meter Ships Fast | eBay

I used something similar to replace rotten injector return lines. I went a size smaller and let the hose sit in the sun to warm up so it would stretch a little more and used needle nose pliers to pre-stretch the ends. It was a PITA to get installed, but it did not leak in the 6 or so months that it was on there. Also required careful use of a razor blade to remove. I would have kept it longer, but I have a set of new delphi injectors and new return hose to install with my rebuilt IP.

Also, I had good luck using a small 12V compressor on the return line to pressurize the tank slightly and prime every thing to the IP. If you use too much pressure you could rupture a line somewhere.

I work at Autozone and found those pesky clamps one day while cruising the aisles, couldn't believe we had them. I have used and would recommend the self sealing German hose though.

Although those dorman pinch clamps Look Ok I can vouch that they are near useless. The small ears that you grab with pliers quickly straighten out or break off rendering them useless. They quickly loose their spring. Better off buying 1/4 pinch clamps in the plumbing dept. when youre in a "Pinch" Better yet buy the correct hose and end plug / clamp kit Delphi makes a nice kit for around $25. Before I knew any better I bought those dormans and quickly threw them in the trash where they belong. More beneficial to spend your $7 on cheeseburgers imo.


I would buy a Delphi kit which many vendors seem to sell in a repackaged offering by looking at pictures or this from badger in Wisconsin. Hmm his kit says that the end caps included DO Not require clamps which I never noticed. I have a spare delphi kit on hand and just ordered one of these to check it out. http://pages.ebay.com/motors/link/?n...255949&alt=web

From the ebay KRServices (Badger Diesel) listing:
"This is a return line kit for any 6.2 or 6.5L turbo or non turbo GM diesel engine. This kit includes more than enough line to do the full job with 8" of line per injector rather than the 3" that the competition offers having only enough to barely do half the job. Thats 266% more line! This kit includes 64 inches of line and 2 caps for the end injectors. Neither of these items require those troublesome clamps put on by the factory because they are made out of a special material that seals onto the injector. This is not the cheap chineese stuff that I see listed on here for a similar price and can be identified by the yellow stripe on the side of the line, this comes directly from Germany. If you put the cheap stuff on it will become brittle and crack in only a few months. I am able to offer this at a low price because of low overhead and factory direct ordering, not cheap material cost. If you have any questions feel free to ask.

If you have any problems with this line in the first year due to manufacturers error I will send you another kit or refund your money if you prefer that! I fully stand behind my products and wouldn't waste my time and reputation if it were junk"

Awesome Floyd, I have asked at a few parts stores, nothing as such carried. Unfortunatly its Dorman, quality will be iffy. They look cheap, JC added his experience.

No one should hold working at AutoZone against you, your still OK.
