For the pump, place an add on RCG ( best place to sell and buy ) we all have one or two spares, place the add, see what kind of reply you get.
Also get a propane can, the Colman green one will last you a life time, one can is all you need, not six 😁
You will need a one way Festo fitting fort the gas line coming from the propane electric valve, there is where the tube from the gas can connects during start, a gas filter for the fuel line and one for the gas line on the gas can.
