jeff so tell me when you pump up to say 130 psi you cant get them to cycle one time. i had a problem in the beginning with mine also. the brass pinns where binding on the side of the rtract mount cousing them not to work freely.. take out the unit and inspect very well.. i dremmeled mine down a little. now i can cycle my gear with 65psi... i was also quick to jump on the cylinders until my friend found what was going on... let me know...what exactly yours is doing....pat
