Help on changing o-ring seals for a FX hand pump

[Kevho]

I have an older model FX hand pump with the air discharge screw on
the top handle and on the bottom of the pump. My big error was cleaning up all the "gunk" on the interior tube of the pump.

I would greatly appreciate anyone who has the hands on experience or knowledge and could provide me with an exploded diagram on how to disassemble and assemble the pump properly.

Thanks.

I too have an FX pump, not that old,2-3 years. It worked fine until one day it pumped to about 2/3 full and suddenly" let go". Pressure stayed in my cylinder but all pressure went fron the pump. Next time I tried it,a couple of days later, the same thing happened. I have since fitted a new seal kit but symptoms are still the same. It wasn't hard to fit the seals. Any suggestions? Thruxton.
