I have some fuel leaking from, my overflow valve. So I'm going to just replacement it. I'm looking at the one from LarryBs, and one on ebay is from Dieselcare ,that seems to be the same one LarryBs sells, but its free shipping, compared to 14 dollars.Have you guys had good luck with this style of overflow valve?

I'd stick with the factory Cummins. That may be what LarryB's is, I don't know.

The only thing to leak would be the sealing washers, why not just replace them? Cummins #3818192.

I've read some thread's on here about the stock OFV not sealing well and about the check ball wearing out from a pore design .Is their anyway to check the old valve? Then just replace the seals.
 
Never heard that one but, yes, you just need to remove it from the pump and remove the bolt in the end of it. It won't spring apart, by the time you have it all the way out there is very little, if any, spring tension on it. It will have some shims between it and the spring, so be careful not to lose them. Remove the spring and if it's not 1/2" long you can stretch it back out for a temporary fix. It will collapse again over time. Make sure to put the new sealing washers on.
 
Just take about an hour sometime and read through dieselcare negative feedback see how many people they screw and you would be smart to not buy anything from them
 
I wore out three or four stock Cummins OFVs in about 600,000 miles. I've had one Tork Tech valve in about the same amount of miles, and it is still working just fine.

This is the description, prices might be less from another vendor. http://www.dieselpowerproducts.com/...MIuqy2oLDG1QIVSmp-Ch1x4AeAEAYYASABEgKUSPD_BwE

How was the installation of the tork tek?does it just install, like the oem value? I read the tork tek value is preset to oem specs 29 to 32,so is it screw in and go, or do I need a gauge to check the set point.
 
If you don't have a pressure gauge I recommend you get one, not necessarily for the install, but it is a valuable troubleshooting tool. Mine came preset, but the lock nut wasn't tight enough and vibrated loose. So just like the OEM you can take it on faith it is set correctly. Install is just the same.
 
I just got my Tork Tek overflow valve in the mail.I ordered the OFV010 AND THE COMPANY UPGRADE MY ORDER TO THE OFV020 VALVE, which I can use with WVO or biodiesel, will install it saturday. I did notice the holes drilled into the valve seem low, but I assume its designed that way?

So I got the overflow valve changed over to the tork tek valve. Here is a pic of the old one compared to the new one, the end hole is a lot larger on the old valve and the side holes are drilled where it would be in the center of the banjo connection., compared to the holes on the new one is closer to one side of the banjo connection. I'm guessing if the new one was drilled wrong ,I would have problems with the injector pump.

The adjustability of the TorkTek necessitates the holes being where they are. If they'd drilled the holes in the same location as the stocker the valve would have to be taller and you'd have to pull the pump to install it, IF it would even fit between the pump and the head.
 
I figured that's who he was referring to.
When I bought my adj ofv from TT, it was never delivered, they sent out another immediately.
2 weeks later the lost ofv arrived. They said "keep it". :D
