Sorry for the delay, I don't check in here too often lately. I got to digging around and the closest I could find was a manual for the 413g on coleman's website. For usage, it's fairly accurate, but you can pretty much ignore the part numbers.

Also, coleman does still sell parts for the 425e from their website, if anything's gone bad on yours. I just ordered a check valve, air stem, and plunger for mine. Just type in 425e into the product number field at

Hope this helps a bit.
