mechohaulic Posted 8 hours ago Share Posted 8 hours ago time for this ole man to further his education. I've been requested to check a superliner having E9 V/8 400. this is basically a toy truck not at the moment daily workhorse. sits for months at a time (4-6) ? when attempts made to start there is fuel loss . it has the primer pump on the baby v8 injection pump. does this primer have same two nylon T shaped check valves as the old school 6's had ??? I don't think there's a problem other then the lapse time between starting. told owner I would check with greatest source in the world the BMT crew ; so here I ask. plan is to go back fire it up for a while then go back in day or two restart. no fuel leakage .didn't put alot of time on it today; hay baler down at the farm took too much time . two projects 10miles apart. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75847-superliner-e-9-400-prime-loss/ Share on other sites More sharing options...

Thanks for the heads up Joey ! ! Try to shed so light ! The aforementioned orings are highly suspect! If it has plastic line check them also any thing with that oring with a squeeze nut on it also suspect the primer it self has to seal properly as well!anything on the drain side of the pump before the check valve on the right rear corner of the pump! Needs to be checked! Happy hunting Mechohaulic! 😂😇 Quote Link to comment https://www.bigmacktrucks.com/topic/75847-superliner-e-9-400-prime-loss/#findComment-580589 Share on other sites More sharing options...
