Need help please with my Rrfpr

[quiddo15]

So I noticed today after going for a spin on my Rxpx that the colour of the clear tubing closes to Rrfpr gauge is a brown colour, can someone please tell me what the cause of that would be? I will add a pic just incase there's any confusion to what it is I mean.
Thanks

Just a guess but intercooler leaking a little water mixed with oil from charger seal boosted into Your clear tube

This sounds plausible. I know how to fix it - replace the clear tube with a blue silicon one

The end that connects to the intake mani still looks clean so might not be the case?

Most likely condensation build up in the reg? I would split the reg and check the spring for corrosion?

Does it look like there is goo or some debris in the colored area? Or did the plastic just change color?

[quiddo15]

There's definitely goo a bud debris in there. I didn't notice any change in performance either it was going strong all day. I'm running a les cooke C kit.

Take it off, see if the mixture is oily or gasy smell.....Clean it out, put it back on.....See if it comes back......My guess is that under vacuum, its pulling any oil/grease from the spring that is used in the diaphragm assembly....

Looks like rust. Its always best to point the reference line down to help drainage.

[quiddo15]

Ok I will give that a crack. What's the actual process with pulling the Rrfpr apart? I know how to take the tube out of the manifold but I have never tampered with the actual rrfpr. In regards to the tube itself are u saying to have it facing down for better drainage? Thanks for your help

[quiddo15]

So I just pulled the tube off the Rrfpr and it looks like rust. What's the best way to clean it?

You need to split the reg for inspection, clean or replace the internal spring and diaphragm.

Can u just buy a new spring and diaphragm if so where from?
Thanks for your help mate.

That's a Riva kit, so I would contact Riva or you could try Jerry; [email protected].

I wouldn't think that it's normal to have it corrode like that, that quickly (assuming the reg is as new as it looks?). Condensation could be building because of how/ where you store the ski? Do you store it garaged with the seat off?

[quiddo15]

I only just bought the ski but I'm assuming the guy I bought it off stored it with the seat on, I always store it with the seat off. I need a 3 and half mil Allen key to split the reg so I will get onto it tomorrow. Hopefully it just needs a good clean. Will I have to reset the reg after splitting it? Cheers

Yes but you should just be able to reset it to what it's at now.

Here's Rivas recommended setup, http://www.rivaracing.com/instructio...0_rrfpr_08.pdf, without o2 its a good guestimation
