When it works I'm on top of the World, but it's depressing when there's a problem!
Went on a 2,000 mile trip to the mountains. Hit a hard bump in Atl & lost 6" section of fill tube into tank between frame & wheel well liner. (oh yea, I was missing bump stops on both rear leaf springs, which may have contributed to extra leaf spring movement) Didn't know this till after I poured 35 gallons on the ground. Thought I had spilled a little & my boots kept slipping on the grass. Filled tank, checked under there, saw a drip, thought I'd have to tighten loose hose clamp. Laid in puddle of oil & found fill tube gone. Man was i so p!ssed after I just toted it 800 miles, to pour it down the mountain.
Got home, dropped tank & there is still 5 gallons in tank, okay, I thought I ran it pretty well dry since v3 switched off. Had fill cut off & re-welded new 1 1/2" 45* fill tube, angled outboard. Used 1 1/2" ID marine white hose, 4 1/2' long & routed to inner wheel well tube. Cleaned mesh screen, Replaced filter, purged. Found pump was very loud, like no liquids going thru. Pull intake hose @ V3, blew, & it was clogged, but blew until I heard bubbles. purged again, checked return line & oil shot out under purge (didn't see if pump returned oil). Now with pump running I should hear it dripping into tank thru fill cap, No? No sound.
Here's what was happening:
Light was going on and off before I cleared pickup line. But not rapidly. Pressure drops to 45 psi when it comes online, then under acceleration, pressure drops to 40 & system goes back to diesel. Pressure used to be like 68 psi when online.
System will only come on @ idle or de-celleration. Shuts off under acceleration.
My thought is fuel pump was stressed running w/o oil? On boats, impellers have to be replaced when a pump runs dry. I'm not familiar with this Fass pump, & how much abuse it can take. From what I see the purge selinoid does the purge, but does the pump return oil to tank when offline? Pump runs at all time in Auto mode, correct?
So basically I'm not building enough pressure?
Pump is not as noisy now, but is it working, or is there something else?
still have low pressure @ 45 psi also.
