Injector for ISM 500

[Nilao]

You can use a Turkey baster with a long plastic tube to suck out any excess fluids from the cylinder. I wouldn't put a new injector in without getting the majority out. But I'm overly cautious about hydrolocking a cylinder.

Typically tips dont get "blocked" they can carbon over and cause the fuel to stream rather than atomize but at 30k+ psi at the tip the don't clog. They can also stick open internally and cause fuel to constantly enter the combustion chamber. But that's usually confirmed by a bubble test.
