Here is the story:

I drove the 2001 truck to work today and while we do not have assigned park places, we usually park in about the same place. I noticed that where I parked yesterday was big oil spot. After a minute of wondering about it, I got to thinking "maybe its me". Sure enough its me. I do not have a paved driveway so it did not show up as easily.The hpop line to the drivers head is leaking at the pump.


Here is the question:

The line is actually leaking at the quick connect on the pump. IS there an oring that goes bad in that coupler and has anyone tried or had any luck changing it? OR am i just better off putting a whole new line on it? I do not plan on keeping this particular truck, so I really am just trying to make it run pretty good and keep my expenses limited in that process. But I do not need it pouring oil at the same time.

 

I consider line to be good preventive measure, with age, not extremely pricey through Clay Riffraff Diesel Performance Parts: - HPOP Lines That being said, there is an internal oring.

 

Yup, I did the whole o-ring rebuild deal with my 7.3, injectors, turbo, HPOP, you name it.

 

Most likely a o-ring on the fitting common to the HPOP. You can get new ones from Clay or Bob!

Here are some pictures of the internal o-rings and the ones on the fitting.

 

Excellent post Ken. Thanks . Rep was a no go.

 

No problem Robin! Always keep these things around for just that type of question!

 

Fantastic info!
I must have the early style STC fittings that only came with 2 o-rings. That other fitting looks like it might work much better then my OEM style. Where do those come from? Do they work with the original style HPOP lines or has the design changed to work with the new fittings. (although it doesn't matter in my case since I've already proceeded down the JIC route....)

Oh yeah....reps deserved but it says I have to spread the love first.

 

Thanks Ken. That is what i was hoping to see. I am about to order the stuff to fix it now. I need an ebp tube for my 2000 so I can knock both orders out at one time

 

Bob carries the new style fittings on his website:
Diesel O-Rings.com Head Fitting
Diesel O-Rings.com HPOP Fitting
The second o-ring is really more of a dust seal than a pressure seal. It just helps keep the dirt out. They are both compatable with any STC fitting.

 

Thanks. I didn't notice these when I was on there last. $15 per fitting on the head side isn't too bad....$29 per fitting on the pump side is a bit steep. I wonder what the difference is? Perhaps it's a custom fitting to accommodate the check valve springs?

 

That's the difference. Double the price to run a drill bit to open it up to accommodate the spring check valve. It's a larger thread also but I think they give you that part for free. LOL

 

Eaton is pretty proud of these fittings. I bought a few fittings, caps, and plugs to make some HPOP test tooling and it consumed a hudred dollar bill pretty quick. Below is the invoice. My guess is they have the market on them and they build smaller lots so the cost is higher. Just the fact that Bob stocks them is impressive to me. I had to wait a month to get mine.

 

Ken, reps sent.

 

Seams reasonable when you think about it that way. Just one machine operation can easily add $15 to the price of just about anything these days.

For those who delete the check valve assembly....is the dash 6 ORB fitting available in the new style without the machine work? If so, could one presume it would be about the same cost as the dash 5 fitting?

Yeah, Bob is a great resource and makes it possible for me to work on my own vehicle and get those hard to find parts. I walked into my local Parker Store the other day to buy a couple dozen Vibra-lok sleeves and the guys behind the counter all had a blank stare on their faces and told me they don't carry those any more. I had to pull out my cell phone, browse to Replacement O-rings for Ford Diesel Engines and show them what the sleeves looked like. They recognized the part immediately and walked me to a wall full of bins where I could pick out the size(s) I wanted. I would be just as lost as those guys if I didn't have the benefit of Bob's research, online catalog and helpful tech articles. Thanks Bob! (BTW, you'll be seeing an order from me soon for a couple more FPR kits....)

The STC parts are hard to find in our area as well. Any of our fleet trucks that pop a hose on the jobsite gets retrofitted with JIC style hoses because the STC stuff isn't stocked by most field repair trucks. Our choices are to hire a huge tow truck to drag our broken down crane truck to the dealer for a new hose or just have it replaced on site with a different style. The STC method means we pay at least $500 for the tow, $300 for the hose and a lost day's revenue. The JIC field repair is about $250 for a pair of hoses and we stay on the jobsite and get the work done in most cases. From a financial perspective it's an easy decision for us.

 

Yes, the STC fittings make complete sense from a production standpoint. They install quickly and are pretty easy to remove and install. I suppose if your company stocked everything (no company likes inventory these days) you could be equal. On the side of the road and you are up a creek. I keep spare HPOP hoses and fittings in my truck along with o-rings and tools......That way i will never have a failure!
