Review on Efficient Ford 7.3L Injector Sleeve Removal/Installation Tool Kit - Replace F4TZ9F538A, 1814376C1, 1833564C92 & More - 1994-2003 by Michael Finnegan

Bought because other reviewers might not have repaired and installed properly. Spring. You're right. This kit sucks! Do not buy! This went on for several months and now I have to go back and do it all over again. The sealing rings are leaking, the cups do not correspond to the factory dimensions. 3 or 4 cups started coming out. Before you start wondering how I'm doing "Hmmm. He must have done it wrong." I did. I do this for work. My friend wanted to use them because it was a 'good price' and he was unemployed due to the lockdown. Please use Ford parts. Pictures I'll add later.
