Check the listing for details. Coleman Lantern Pump Plunger Assemble - Fuel Pump w/Clip & Screw Nut. 1950's-70'. Condition: Used. Listed at 12.95 USD. This is the most common sized and installed fuel pump produced by Coleman.This size was used on most Coleman lanterns from the 1950's to the early 1980's changing over to neoprene cups and plastic end caps with later produced 220k models.This pump assembly has the screw on end nut which holds the leather cup on.All pump assembly's are in good (buy dirty) condition. No rust or damage. Just needs cleaned and/or polished. NOTE: You may have a lantern with a neoprene cup and "pressed-on" end nut for earlier model lanterns. Coleman changed over completely to neoprene cups with late model 220k. You may find screw or pressed on nuts, and either leather or neoprene cups. Especially when so many lanterns have "replacement" parts from users over the years. If you are restoring an older lantern, you can change to a leather cup and the much easier to use screw on end nut. Each comes with a NEW leather pump cup. If you have any questions as to what you need, please just ask. Shipping is USPS with tracking.We do have other Coleman parts and do combine or refund excess shipping. Thank you for looking.
