Default v2 - d2 filling up wvo tank

Hey all,

I lost a half tank of d2 in a very short time today before I realized something was up. My WVO tank is full now to the point of overflowing soon. On the v2 system, could the purge valve be the only culprit? The check valves on the cylinder heads are there to prevent wvo flowing to the d2 tank (correct?). Would unplugging the purge valve prevent d2 from flowing to wvo tank? I don't have much head room in the wvo tank for trial and error at this point so the truck is pretty much inoperable at this point, and I really need my truck going. Are these older purge valves still available?

Thanks,

Brad

Default V3 details. Not sure if v2 is the same

Pull fuel feed and fuel return off of tank. Have someone start truck on d2. If Wvo check valve of system is bad diesel will come out of Wvo feed. If check valve is bad d2 will come out of return. This is while running on d2. D2 is at about 55 psi so it sprays hard. If itís check valve you can put a vise grin on return line going into Wvo tank. This is for v3. Not exactly sure about v2 bit pretty sure they are the same. V2 just looks different you could pm me your phone number

Default Said one part wrong

If itís bad purge valve you can clamp return line. Potentially unplugging it will work. Check valve can be cleaned but probably needs to be replaced.

The only check valves I have, to my knowledge, are the ones up on the cylinder heads.

On the V2 is a check valve and a purge valve. the CV is in line with the vo feed line to the heads. The purge valve is in line with the return line to the tank.

Where in line would the check valve be? I crawled underneath the truck, and I don't see a fitting in the veg line going up to the truck.

Thanks,

It;s been too long since I had a V2 so I cant recall. Find the return line and you'll find the purge valve ahead of it. Then find the supply line and you should find the CV.
Do the test that was outlined above.
