Title: Injector return pipe: anyone found anything better?
Post by: Lonewolf on January 26, 2012, 07:55:20 pm

Hi all  :)

  I keep getting diesel leaks from my injector return lines, and i was wondering if anyones found a harder wearing substitute for the over braided rubber hose?

I went to my polaris dealer and got some clear primer hose, fits real tight and has worked for over a year so far.

I've been using 1/8'' ID x 1/4'' OD Tygon hose for past several years.
Been really pleased with it.

Some of it is translucent yellow, and some clear.

Places that service lawn equipment weedeaters chainsaws and such will have it in stock.

If you get anything like this - DON'T get the thin wall 1/8 x 3/16

Napa sells the right size fuel line. I had similar issues, and after trying vacum lines and an assortment of other hosing, the fuel lie from NAPA has worked great.
