    Everyone should have a spare in Glovebox. These are a nice mild steel so you can use a magnet to pick it up when you drop it!! LOL!!

    HPOP Res. Fill Plug Perfect Fit

    Posted by Jonathan on May 6th 2019

    I was recently changing my oil on my 2000 F-350 and HPOP reservoir. Got the plug out and it is now lost forever. RiffRaff Diesel set me up inexpensively and quickly. Will be doing business with RiffRaff again.
