so i had to replace some of my fuel hoses recently and once i was ready to prime the low pressure pump i found that there was nothing i could do to eliminate air bubbles coming from the filter into the clear fuel hose.
i even removed the supply line and connected my vacuum pump directly to it and got a clean flow of diesel. i primed the filter and the supply line and reattached everything i continue to get air bubbles from the filter.
the filter is new (<1,000 miles) so it should be fine, unless i've just manhandled it too much by taking supply line on and off and somehow broke a seal? also, now matter how hard i try i can't seem to be able to open the bleed valve.
i'm about ready to tow it to my trusted mechanic, but thought i'd make one last effort on here to see if anyone can advise.
i could also bite the bullet and buy a new filter and just see what happens...
i should add, i didn't replace o-rings on any voss connectors, just used a liberal amount of silicone grease when reattaching.
AND... maybe the water sensor o-rings need to be replaced... is that a common place from which the filter takes on air?
