i ran my fuel lines to my p pump today and cylinder 1 and 4 are leaking fuel out from the dv holders. im waiting for my dv socket to come in but im wondering if theres copper washers or orings or anything in there, or do i just need to tighten the dv holders down some more?

thanks

 

there is an o ring on every dv holder, they are very easy to cut. Some pumps have a copper sealing ring below the DV. I'm no expert on these pumps and I have heard some say you do not need them and others say you do.

The best advise I have gotten on that topic is ... if it came with copper sealing rings replace them with steel ones, if it had none to begin with then there not needed.

 

there is a o ring on the holder torque the dv holders to 85lbs in one quick turn

 

when i did my dvs a few weeks ago, i took the copper rings out and i dont have a problem with leaks and it runs great, i did notice the rubbers seals were really dry and i tore one, it now leaks, so i need to replace all my rubber ones, i also didnt use a torque wrench, maybe i should have, i just put them back really ****** tight

 

cool thanks for the answers guys. are they some special o-ring or will my random kit with 5 million orings have one thatll fit just fine?

 

I think its a special ring, I'm sure you could get some from the fits all kit that are close. A new set of six o rings is arround 30 bucks from a cummins dealer.

 

they are a special oring

 

Thats what I figured but was not 100% sure

 

well looks like ill be going to cummins in the next day or so then

anyone got some part numbers?

 

Isn't the O-ring just a seal to keep dust and dirt out?
