I have a stock (no tubers) 2007 Dodge Cummins 6.7
Recently when I punched it to get around someone right after the turbo kicked in it suddenly lost power. I punched it a few more times and the check engine light came on. When I got the code it came up P000F fuel overpressure relief valve activated.

I was going to replace the valve but it's $455.00

I've seen people have put a plug in the fuel rail to fix this but I worry about too much pressure cracking the fuel rail or injectors (more expensive).

I've also seen people shimming this valve with a washer shim kit.

Is this what my problem is and if so what is recommended to get my power back without too much pressure to cause other damage?

Please help

 

DON'T, under any circumstances PLUG the bolt. Your gonna have to bite the bullet and buy a new valve. You might get lucky, and Cummins will have one on the shelf.

 

I was definitely not wanting to go that route of plugging. What about shimming maybe with only 1 or 2 washer though instead of the 3?

Is this a cummins part? It was my understanding that the fuel system was a dodge item. Would this be covered under cummins 100,000 mile warranty?

 

Check out oregon fuel injection. Oregon Fuel Injection, Dodge Cummins diesel performance, common rail parts and fuel supply pump just bought a rail pressure sensor for a 6.7 for 140 bucks. The dealer wanted 500 plus another 200 to install it.

 

Personally I would put the rail plug in. We done that to many trucks and had great results

 

If customers start blowing nozzle tips and melt an engine, would you pay for a new engine?

Familyman, the valve is there to keep from cracking injectors.

 

I am running dual CP3's and have had my rail plugged for 6 years with no issues. I wouldn't expect Industrial Injections to replace my engine if I melted a piston and that's who I bought the rail plug from years ago.

It's diesel performance, things can break and go wrong. You don't buy performance parts to make more power and then expect the manufacturer of that part to buy you a new engine when it breaks

 

ive had a rail plug in my truck for well over 2 years now and ive yet to throw a rail pressure code. is your stock lift pump bad?

 

We have been doing this for years on trucks with dual cp3's and running pressure boxes and not had issues with this and we do the same on duramaxs as well. By deleteing that rail relief valve is the only way to aleviate not having those codes again. i stock one will just do the same later on down the road

 

mine is plugged and running a pressure box since 08 no probs if your that worried about it shim it so you will have a little give somewhere just my thought
