Took the pump off over the weekend. Part No. is 174264. Also has 14 (or L4) HJ B marked on it. Need to know if this is the rebuildable type. Seloc manual says they’re throw away types-waiting for the Clymers manual. And where can I order the kit for one of these? My engine is an EL120TLCO with serial number G1025087.<br /><br />If I go buy a vaccum gauge tonight, can I test everything before the pump? Do I disconnect it from the pump?? Anyone tested for this before? Primer bulb wont stay primed. Need a bulb operator at the stern!
