Matt; Yeah, I have been eating my Wheaties lately. I have always just had to "tap" the tube into the pump body, usually with a wrench around the shoulder and a small hammer. I never saw a need to press it in, but I only pull an AMC six apart about once in a long while. What does the TSM say about doing so? I haven't had a six let loose on me in years, and always from a PO. I am putting a lot of dough (for me anyways, I'm a cheapskate)into my 4.0 build up and don't want any surprises....Russ __________________________________________________ Do You Yahoo!?
