Injector top o-ring and spacer issue
Last week I pulled my camper for a week long vacation. Made it to the campground fine... the truck did great job as usual. The 2nd day I went to Wally World and the truck lost ICP pressure and broke down. Got pulled back to the campground and tore into it.
It turned out to be the top of an injector. Looked like the retainer clip gave up and let the o-ring and steel spacer slam up the nipple cup. The Retainer clip was out of shape and the spacer ring was split in half. All three pieces were at the top of the nipple where it flanged into the ball cup.
I got a new injector and put it back together. You can imagine how fun that was away from home without your tools and shop.
A week later we leave and come home just fine. The next day at home I was running an errand and the same thing happens. Different injector... same exact findings. WTH is causing this.
It's the same scenario of hard pull of the camper, pulls fine and then when not loaded.... next day the top of the injector blows apart.
I need to find where to get that steel spacer. I have the o-ring kit (ISK-102) but it doesn't have that piece.
