Well the trip went excellent. The truck handled the ride just fine, and broke 118,000 miles on Tuesday. In fact, it handled like a dream. It didn't seem to care about the altitude at all. Had great power the whole time. Can't say the same for some of the other rigs I passed and got passed by on the way.

A 90's 7.3L Powerstroke passed by me pulling a 6% grade at 4000' and he had a light haze rolling from the tailpipe the whole way up. I got the check valve is earlier this week and it should work well. I think I might be lazy on this one and wait till open shop in a few weeks at the school to put the truck up on the lift to install my relay for the Walbro, get the check valve installed, and double check my work after its had the time to get some miles on it. The guard plate that protects the filters from debris slung up by the tires proved its worth on Saturday as we ducked away from Sedona and hit 12 miles of rough, bumpy gravel trails to go trail riding in the mountains on horseback. The filters don't have a scratch on them. But the plate actually had a few dings in it where it looks like a couple rocks hit it at high speed. If those rocks could leave a crater in a piece of 1/4" steel than imagine the damage it could have caused to an unprotected filter :EEK:
orrum, I got the check valve off ebay:

It seems like a decent quality piece, but only time will really tell I suppose. He does have other sizes for different I.D. fuel lines if you need as well.
Once again, overall, I'm EXTREMELY pleased with how the system came together and how it performs, even under some of the toughest conditions. I'd say mission accomplished :thumbsup: Who knows, maybe even when I get back to PA this winter i could make a kit for these or something.
