    The O Rings arrived on time, yet we never received them. Finally found out the our Post Office had a chemical spill, and it got on our package,making it undeliverable. This company worked with us to 2 Day ship new ones to us and refund our payment. Thanks Riffraff Diesel!!

    As usual, Clay has the best prices and the fastest shipping! Make sure and soak these in oil before installing!

    Injector O rings

    Posted by Unknown on Dec 19th 2018

    I was burning about 1 gallon of oil every 25 miles. I installed theses and I burn near no oil now. Took me about 11 hours to install but I'm a shade tree mechanic at best.
    BTW after running that much oil through my fuel system I needed to put new pre filters in and replace my fuel pump.

    Don't bother with any brand of o-rings other than Alliant (You'll regret it sooner or later....most likely sooner.). Great quality and fast shipping as usual!
