Long time no post.  Glad to see you are maintaining your old site as archive.

Me, I've still got beaver problems, and fuel line problems on my dozer.

The dozer has had an easy summer, since I needed work it couldn't perform.

"Spinal stenosis at T-10 arising from Ossification of ligamentum flavum.."

So now I can walk, after spine operation, but can't dance.  Couldn't dance before, either, so no big deal.

anyway, to catch you up, the beavers have had a good summer, and they could have a good fall and winter too, except for the fact that the upstream neighbor's daughter is getting married in two weeks and they sure would like the stream to be streaming on their property instead of being a pool backed up from my dam, as augmented by the beavers.   (This would seem to be a reasonable request for those who don't know the whole story which I won't repeat for fear of over-boring those who read it before, elsewhen.) (It should be further noted that my wifey  has entered into the discourse  on the side of the neighbors, so  i am entirely overmatched on this one…) 

====================

So anyway, I hotwired the dozer into starting up

( the ignition switch is apparently retired from active duty, and I was too lazy to take the plate off and see why it ain't gettin' no current to distribute),

after filling the tank, and went down an de-dammed the dam, just in time for the engine to start to want to die.

Turns out that the engine runs like a champ as long as their is a positive "head" from the fuel tank:  soon as it's below that, I think the fuel supply line sucks air, and it will barely run at an idle.

Which  means I backed up all the way to the barn to keep the fuel tank a bit higher.

Anyway, as far as i can tell, I have a crack in the fittings and line which constitute the fuel return circuit, which delivers fuel back through a filter mounted on the firewall.   I'm not sure if these plastic fittings "snap on" a metal nipple on a banjo fitting, or whether I need to remove the whole injectors, which was what I thought I would need to do when first I noted a leak near or at the front injector. 

I'm not sure where to go or what to ask for…??

thanks.

(I do know that when I go home, I have to refill the tank, and do the job over.  I have become soft hearted and do not want to kill beavers anymore, but they are trying my patience.  Actually, it's the upstream neighbors that need to……..uh, never mind…)

Thank you Bob.

Yes, this is the low pressure return side.  The return goes to the right, over near the "firewall", and recycles through a "plastic bowl" filter apparatus which also has the fuel shut-off, and the supply line which leads to the high pressure injector pump. 

I would presume from your comments that there is probably something like a "zerk" fitting nipple connector that has these plastic push on fittings which make the hook up of the return lines easier:

if so, then, I guess that I could just pull off the plastic cracked pieces of crap, and make a "normal" connection with teflon tape and a hose clamp??

==================

On to the danged plastic "clear" water/sediment collector.

I took it off, as it looked cloudy, and discovered there was zero water or sediment in the fuel: a good thing:

but putting the bowl back on was problematic, as the plastic had swollen enough to not allow easy reinsertion.  Anyway, before trimming the circumference down with a grinder, I've ordered a clear glass bowl from NAPA for $11: I'll know this afternoon if it fits.

"Turns out that the engine runs like a champ as long as their is a positive "head" from the fuel tank:  soon as it's below that, I think the fuel supply line sucks air, and it will barely run at an idle…."

The above is bogus, the tank was still essentially full after 45 minutes work.

My "new theory" is a vacuum lock arising from the unvented fuel tank, combined with the leaks in the return line, allowing air entry, prohibiting any engine RPM above idle. 

Another day, another theory: eventually a right move will eventuate.

Those bastard beavers have completely replaced the damn.

===================

I cant find my "laser designator" I made from a carpenter's level, so broke down and bought a "integrated flashlight and laser targeting system" from a sporting goods store, reduced from $59 to only $29, today:

I'd say the device would be fairly priced at $9.99, but nobody asked, so I paid:

and now will murder some rodents, since the carping and whining from persons in my vicinity has made it necessary.

Thank you.

The fuel lines on my fiberglass rounded beauty bulldozer

appear to have a plastic union they plug onto.

Being the lazy person I am, I drizzled superglue on the split, and it has held.

Leaving the apparently unvented fuel cap a turn loose from the bottom has helped.

Next problm up is the fact that the ignition switch  gets no power.

Are there fuses?

Luckily the dozer starts easily with a "hot wire" across the solenoid. 

=========================

Thank you very much for your assistance.

===============

PS: Killed two beavers, fed local coyote,

the circle continues. 

I could quibble about the glow plugs needing energy thru the switch for ignition,

and therefore ..

But i shan't, since I've already said I cn start the unit easily by hotwire,

which bypasses the glow plugs, rendering my quibble ALSo wrong.

Correct, the gauges and headlamps are inop.  

I've looked for a "fuse box", or an in line fuse holder to no avail, but I might be (likely am) missing something.  Than owner's manual would be handy.

Oh well, I have a voltmeter or two laying about..

That will be a help.

Based on my recollection, and cross correlation to the picture, I think that it is the voltage regulator which has a loose wire, green if I recall: ormaybe blue i forget.

And the fuse which blew I believe was the protection for the starter solenoid wire which had come loose and probably dangled to a nearby ground.

Re-reading good book, entitled 

"How to Use Power Washer Without Fxxxing Things up"

I thought I had it memorized from the first time I washed some paint off the car,

which cost $239  or so. 

  it was Wifey's car
