did the design of the lift pump ever get revised or something ? on my '80 and on my '85, they both flow "normal", like they both always have, which is not particularly alot, even with all tanks and screens and filters and things all clean as new......on someone's '83 i was working on, i couldnt help noticing it was pumping fuel through "like a firehose" and you could quickly fill a gallon jug with fuel from the return........same thing on someone else's 60x series i was working on......are mine both just old and weak and need rebuilt ? or is there a difference on certain years ? i had always understood that this old fashioned mechanical pumps were almost indestructable, but after seeing this post about kits, i can appreciate the need for the components to be new and in order, and not 300k + ......
