    fuel injection hose clamps

    what options are out there to use for fuel injection hose clamps? think that worm gear would eat into the hose. factory clamps need a tool. looked at automotive injection clamps. can't find any locally that are small enough. i guess what i am asking is what are you guy's using and having good results with? this will be on a msx 140. thanks in advance!!!

    The factory Ear/Pinch type hose clamps are one time use, and must be cut off the hose.

    You can purchase similar Ear hose clamps inexpensively. While a special tool is sold for them, you can also use a dull pair of diagonal cutting pliers. Just be careful how hard you squeeze the clamp so you don't crush the ear

    Sometimes referred to by the well known brand name Oetiker, Ear (aka Pinch) clamps are generically available.

    Gap-Free Ear type hose clamps
    52545K53 or 52545K51 will clamp 1/4" ID fuel line (12mm OD)
    52545k26 or 52545K38 will clamp 1/8" ID oil lines (7mm OD)

    I use McMaster-Carr part number 53175K24

    I dont remember what size though. youll have to measure

    I usually change all of the hose too because the polaris stuff gets very stiff

    Look hear for your needs These clamps expand and contract with temp keeping a constant pressure, unlike worm gear clamps.
