Awning arrived today, holey crap its a big bugger of a box. Water trap also arrived, looking to mount it tomorrow morning before the grandkids arrive at lunchtime to hijack my day!
What a crazy day. Installed the water trap, then the lift pump would not draw through it. I left it running on prime for 10 minutes, bowl remained empty. Anyway decided to fire the engine up and it ran fine even high revs then stopped, no doubt air in the system. Went back an D forth like this for 20 mins then stopped the car and a huge puddle of fuel erupted onto the garage floor, maybe half a litre. After a bitch of a time gaining access to the return lines, found one line hanging loose. Thinking maybe the air pressure blew it off? Anyway, 2 hrs to replace it, not happy, fired it up, got running then second eruption, lines intact but one hose saturated, so pulled it off and replaced, another 2 hrs gone, battery in and out 3 times. Decided to check the end plug on return lines, another hr to get it off but it's ok, changed it anyway.
Now it's 6pm and been at it since 8am, yes I am rooted by now. Car would not prime r run so drove it in gear using the battery and parked it in the garage, tomorrow going to install the small lift pump I carry to run on the return line to tank, have found this works well on the chev so just leave them running for 30mins and should be clear of air, bloody cars, kill in' me
Plenty but not on this car. This whole nightmare started when I added the water trap, which then kicked off what I can only account an unrelated set of activities that has continued to mushroom into the cluster it currently is - the hoses that were leaking were replaced on the drivers side, and one weeping hose on the passenger side. I clamped them up with hose clamps - nightmare spider finger squirrel midget finger stuff, than fired the car up last night and nothing leaked, however the car would then not run/idle. The car stopped like ran out of fuel but the water trap bowl was full and fuel pressure held at 12psi as normal. I cranked the car back into the garage , gave it a kick and curse and went inside.
Today I reinstalled the return line boost pump and this time a sightglass. I fired this second pump up to see if I had a fuel blockage. I was not getting flow thru the sight glass, I ran a jumper to the injector pump solenoid and straight to battery to ensure it was not an ignition issue. I let it cycle for maybe an hour and no fuel in the sightglass, both pumps running and fuel pressure transmitter indicating normal 12psi.
So decided to start it and it kicked on first turn as normal, ran smoothly and then stalled, Refired it a couple of times, would rev to 3K and hold 1000rpm for maybe 10 secs then dies like its out of fuel.
Then got out and discovered more fuel on the ground, appears to have blown the only hose on the drivers side I had not changed, so that is the mission for tonight.
Next will be removal of the water trap as this is where it all started. The flowmeters are gone from the circuit, however I am getting a weird over pressuring of the return line to tank that is blowing the hoses off the injector barbs. The system has operated from the first day without hose clamps, now, the drivers side return lines only require hose clamps and if not the hose blows off, diesel everywhere.
Not that happy, have a ton of high pressure commitments with work right now and supposed to be heading bush on monday for 3 nights. I am sure there is a simple reason for this latest diversion, unsure what it is. The symptoms are like its starving, but the return line pressure on just the drivers side is a mystery.
Anyway, I will see what I get to tonight - any ideas? The fuel pressure is constant and as previous and holds pressure right thru the stall. I though maybe it was a faulty injector pump solenoid - the dedicated battery direct wired solution does not rule that out.
Swapped out the leaking hose, clamps both end. Jury ran the 8mm new return line, need to iti that today if possible. Purchased the additional fuel line sight glasses and fittings - seems parts are scarce everywhere, hoses clamps filters, stocks down or waiting for restock? Going to recheck the recheck of the water trap to ensure its on the right direction and the pressure line, not return line - wouldn't that be embarrassing?
Lift pump post the water trap, so I am sucking thru the water trap and filter, which is fine because the fuel pressure to the injector pump has not changed a bit.
