Found a trick for bleeding injectors on a 5.9 Cummins

Used a cheap garden sprayer with a hose fitting to pressurize the fuel tank cap, got air out in 2 minutes flat, has anyone else tried this method?

Funny you mention that, I tried the same thing but used a handheld pump sprayer instead and it worked like a CHARM. Just make sure you don't overpressurize the tank or you'll be cleaning diesel off your driveway.

Wait @jenkins.reese is this just like how spray solvents always seem to find the one spot you didn't think to cover?

Overpressurizing is actually kind of a feature not a bug if you think about it. I've had way better results pushing that stuff through with higher pressure than any sprayer can give you. Those handheld pump sprayers you're talking about lose pressure halfway through the job and then you're just dripping diesel everywhere. The whole point of using a pressurized system is to atomize the fuel properly so it actually coats everything evenly. Maybe it's just me but I'd rather clean up a little overspray than deal with streaks and missed spots from a weak spray pattern. Plus diesel evaporates quick enough on a warm driveway that it's really not that big of a deal.
