Better fuel return hose

[stewardc]

Is there a better hose to use on the small injector return lines. I'm presently using the old braided-cover VW hose, but there must be something better. Like silicon, for instance

I've seen lots of folks using motorcycle fuel line or chainsaw fuel line with good results...

Better for what?  The braid stuff is easy to install, and lasts a fair while.

why?
if its leaking probably its old,itīs always good to do proper maintenance and just replace that.

I use 1/8" ID clear tygothan from mcmaster.  Fantastic hose.  Super-resilient.  I now have a couple years of use on multiple vehicles and haven't ever had an issue.  It lasts much longer than the braided hose.

my 98 tdi that i used to bbuild my tdi-m from has lime green ones.. ive had them off and on the injectors a few times... aka during the build...

i decided to try them out... and over 13k later still no leaks with bio or diesel..

what they are.... rc nitro fuel line... lots of colors avalible.. cheap... most hobby shops that deal rc carry it... so need a little accent under the hood... there you go..

Wow, thanks for this guys. the Tygothane and the RC fuel line both look good.

When replacing, always look for something better than stock. OEM+

i use vacuum lines.. since i usually pull all the emissions equipment off my ricers, and anybody elses who wants me to take it off, i have a HUGE pile of vacuum line laying around.. i use it for damn near everything that takes small line..

boost lines, fuel return lines (it doesnt harden from the fuel or heat)

Isn't that just like what VW puts on them originally?

basically, but smaller ID, so it fits ALOT tighter on the barb than the braided shizz..

plus, its not braided, so the fabric doesnt bunch up on the ends, and make it about impossible to re-install the lines after re-using them 3 or 4 times..

fish tank air line works good for temporary diagnosis of leaks with the injector returns..

I am using SS braided Teflon......its awesome, but I wouldn't do it if I had to pay for the hose first ;-)

Gave you got any pictures of that ?

I use the regular small fuel line. I think 3/16" is what fits. If you can't find it at an auto parts store try a small engine or motorcycle shop as mentioned.

I don't like the OE hose with the external cloth braid, I think it traps contaminants which cause the hose to wear, and it makes it hard to spot a deteriorated, cracked or leaking hose, because you can't see the rubber. If you buy hose that isn't rated for fuel, either silicone or rubber, it may dissolve in the diesel. I've seen this happen.
