Review on Lisle 13900 Pressure Switch Socket by Eric Speers

Matches my oil pressure feed perfectly on my '07 Yukon SLT 5.3L. Using this head, the 3/8" universal joint, the 3" short extension and the flex head ratchet, you can replace this oil pressure switch by just removing the engine cover. But just in case, I hope you have small hands, because even I have, and I've gotten quite a few cuts and dents from having to reach into the inlet valley 3 times to get a new sensor since it wouldn't stay in becomes the nest alone and he is in a very favorable position for PITA. Had to buy it as the 12PT 1-1/16" socket fitted the new sensor but just screwed onto the old one. Don't know why but this one worked great on both.
