New Fuel Pressure Regulator Spring/Seal Install Got Question

[jrw1234]

I just installed the new updated blue spring with the new fuel regulator plunger. The old fuel pressure regulator housing seal was leaking. I picked up part#1854267C94 from the local international dealer today. My question is when I got the kit, there was a new plunger with a green rubber oring installed on it. The old plunger had a small rubber black seal on the end of it, the new one also had the same small seal on it. I installed it with the new rubber green o-ring along with small flat black seal. I don't know if the green seal was suppose to be installed with the plunger. I included a picture of the old plunger with the an extra green seal that was included with the package. I would appricate anyone input here. I just purchased this truck about a week ago, and I don't need any major problems. Previous truck was an early 03 with the 7.3 international.

housings are different. Internationals is pretty much a 7.3 fuel bowl completley different set up have seen them in F650s. they are not fords 6.0, they are internationals. and i do believe they are completely different internally. If i were you id go get the ford kit.

I got that package in my barn, all I used form it was the new blue spring, all the seals looked fine so I left them. I can grab the international number for you, I think ford just takes the Int. bag and puts it in a bag that says ford with the ford part # on the outside.

In any case, you really don't want to double up on orings, use one or the other, most likely the stock one if they are different sizes.

In searching for an answer to basically the same question but not seeing the answer here. I have an 04-6.0 and bought the blue spring kit 3C3Z-9T517-AG and I too have the same blue green o ring but don't know where it is intended to be placed. on the plunger as jrw1234 had tried or in the cover that butts up to the back of the plunger, seems like a possibility.

You want to follow the directions that came with your kit. There is also a thread you can reference on another forum. Very nice write up for this.

As far as that green o-ring, I didn't use it.

I found the usage for the bluish color o ring is on the outer end of the brass inlet, it is a replacement for the gold color o ring where the fuel line goes in.
