Fuel is in the 50-65psi range. The rubber line goes over the steel line, and the clamp over it to keep it from rubbing through again. When I replaced mine, I omitted the clamp all-together.

DOT compression fittings may get it back running, but I'd opt to replace it and keep from adding another leak point.

Already been said but the passenger side fuel line rubbing through is a well known issue. Replace the line and cover the new one to prevent rub through from happening again

I just wrapped mine in electrical tape and it's holding up fine so far.

I misunderstood, I thought you meant replacing the part we cut off with rubber line.


So here's the line, fixed up.



The bend is gone so it wasn't fun putting it back in. Worst part is the rubber thing that seals the end fell off while I was getting it hooked up, so once we tested for leaks, I had to take it off again to put it back on. Thankfully it had fallen on the ground and not on the transmission or some place I would never find it!

As for the other spot that was about to leak, I wrapped it with 5/16" fuel line, and held it on with zipties:




Should protect it. Man I wish they had put those glowplug solenoids somewhere else.

In any case, we filled the HPOP oil reservoir, cranked it over and it started up! Yay! Made some kinda bang bang bang noise, like someone was hitting the engine with a hammer, but hopefully the owners won't notice. Just kidding!

That's all folks!

This is true, that's a pretty long run and the diesel does vibrate. Combine that with the Parker Sleeves at the ends and I see it as a leak waiting its turn to happen.

You should see the truck. To say it's beat would be kind. Like many, this particular company doesn't invest much in vehicle maintenance.

But we know that doesn't cut costs. It just shifts costs from maintenance to repair. And repairs cause more downtime, at unplanned times. But heck, like Sinatra sang, everybody has to right to run their business their way, right?

I got one too.

This one is easy to fix though. TIG is your friend!

The turbo had been replaced a few months ago by the previous owner's shop of choice but the damage had been done; lots of little turbo center section chunks were all over inside the pan.

This pickup started and ran just fine. No long starts after sitting, no low oil pressure oh, nothing.

You can mend that with a TIG? I'm jealous.

It sucks being a cast piece that has been submerged in oil for the last 20 years but yes, it can be done with decent results (can't be any worse than it was).

Isn't that the front cover? How rare is a 7.3 front cover in Montana? Dude you work too hard. I mean I'd hire you in a nanosecond but think about the bottom line.

I have spares, a few actually. However, this one is PRISTINE other than this little scratch. There is ZERO pitting or evidence of cavitation in the water jacket/water pump area. It was really worth fixing instead of scrapping.

Bottom line....What's that? I haven't had one of those in a long time. I lost $1200 ($1800 if you include labor) two months ago because I had to rebuild a 4R100 for free due to the installation of customer-supplied aftermarket parts (that I had always made a rule against until this ONE TIME) that failed. New pump, torque converter, and rebuild kit in that one. I made the decision to never work on anything for anyone again. That lasted about a month when I came upon a person who needed an engine replacement and I saw a chance to recoup my lost funds.

This failed engine (carnage thread from two weeks ago) is going to be a freebie as well since I have already replaced the engine but feel bad that the replacement I installed ("good" used) doesn't run as good as I remembered when I ended up with it a couple of years ago. Now it's getting replaced again with one that I will make zero dollars off of to rebuild and install. I'll be into it about $500 plus about 20 hours of labor when all is said and done. I couldn't let the guy have the pickup back in its current state....I hath too much pride to send it out as-is....So I am going to make it run correctly regardless of the loss and the fact that he's just going to sell the pickup once it runs again.

I have never lost money on a job or been into stuff for naught like I have these past two jobs. I was supposed to have made money on these since I have two big expenditures coming up in the next month and I haven't been able to save a dime for either one since I keep putting money in others' vehicles. I would have been better off NOT working on other peoples' junk to make money to pay for these other things (money ahead). I guess the problems came about because I had an end goal in mind: Instead of the main focus of doing these jobs to help people get their 7.3L vehicles back on the road, I needed to make just a little extra money for things I wanted.

I think I learned my lesson. No more working on other peoples' junk. I simply cannot afford to do it anymore.
