Starts with ether and runs well. Shut it off, wait 10 min., won't start. New lines from tank to primary filter - to pump. Had it sucking from a pail thinking it may be the pickup in the tank. Primer pump hardens but won't stay hard. Primary filter won't fill beyond 2/3 full. Thinking it may be the pump or electronic. I would be so grateful for any help. Nearest Mack dealer is 5 hrs. away. Update June 2:: This morning I filled the primary filter full. Engine started right smart without ether. Shut down, removed primary filter and it is 2/3 full. How did air get into the filter. Is there a check valve in the filter housing? Or in the pickup tube in the tank? I checked for crack in filter housing. I have 2 spin-on filters, no glass bowl. The jumper between the heads is ok. I thank all you guys for replying. I'm going to apply thread seal to the connections,and see.
