    05 hpdi fuel???

    Boat has been run very little the past year, had about 10 15 gallons in it with ring free and marine stabill in it also run little bit on small lakes no hard runnin. noticed it cut on me at a little above idle I thought that its loading up so I put 10 more gallons of fresh gas in with ring free and marine stabill and went to loz to run it boat started right up got on pad went about half mile cut out then quit . Did this between pb2 hwy 54 ? bridge did this several times but start every time tried to blow it out but could not off on with throttle only the same. Had a forth of a tank when all took place looked at fuel from vst drain at bottom no seperation and no water . Was told next to vst are 2 diaphrams 3 10 mill bolts hold in hand pump primer bulb if gas comes through diaphram is bad, Ithink there is 5 filters ? plugs are 20.00 each filters 150.00 pump 700 800.00 dino 100.00 , dont no where to start but thinkin plugs and diaphrams also drain all remaining fuel this has me stumped it seems to run out of fuel cuts out then quits . Anyone ever experienced this before not a lot of money need help thanks you guys are the best.

    Common problem on the HPDI. Correct on the lift pumps, pull them away from the block and pump the bulb up hard and see if they leak. There is a screen filter in the bottom of the VST. Then the "strainer" in line filter between the VST and high pressure pump. Open the top post pinned here and read all about changing the filters.
