Hair line cranks where they meet the injector body can cause issues. Some say to replace them when you switch injectors. I've had mine on three sets then bought new ones.

Check for hairline cracks around the hole that mates up to the injector. Give Jamie at CPP a call. I think he still has a sale on them.

if you reuse the old ones, be sure to match the tube to it's original injector.

best to examine with 20 power eye loupe for cracks and wear grooves on nose. also reverse blow out the filter in the end.

wash and reverse flush with acetone and keep clean before reinstall.
remember, a 10 micron shhitte ball in one of these is like taking a hacksaw to a rod bearing surface
