After I finished my torque rods my truck spent pretty much the entire summer sitting along the tree line in the back of my property. Was a very busy summer with tons of projects and activities, none of which involved my truck. The main problem was that the fuel tank was facing toward the sun, everyday....all day. It was October and I started to prep the truck for a show. I had it running along side my driveway warming up when it suddenly bogged down and stalled. Very unusual...tried to re-start it and the motor did nothing but crank over. The in tank pump was running and and fuel was present. I checked the fuel closer and found I had an algae bloom in my fuel system. Though this didn't help the matter it likely wasn't the problem. Further concensus lead to the HH. So I removed the hydraulic head, broke it down completely, soaked it, cleaned it and re-assembled it with new o-rings, button and retainer. Drained my tank, flushed that out, I had new injector lines so since my originals were hopelessly stuck on the HH I cut them and replaced them all. Once everything was backed together, I flushed the whole fuel system with about 10 gals of gasoline to kill any algae. Then drained that, filled with fresh Diesel, changed filters, and she fired right up.
