Any ideas what this is

[paulsimon]

This looks like one of those small in line fuel filters. It lives behind the fuel filter and has something inside that rattles like crazy. I need to know what it is to order a replacement.

Thanks in advance.

Looks like a pressure regulator buddy but never had any dealings with them on the 850.....

I'll take another look when I get a mo and also look in the Haynes.

Doubt thats a pressure reg, looks like a 1 way valve to me, maybe even a vapour trap?

Just had a quick shufty at the haynes, cant find the item in the pic :(

Is there a fuel return pipe to the tank? I had one on my previous diesel truck.

Thanks for your responses so far.

Its the rollover valve.

I guess it stops any backflow through the pipes if the car rolls over thus preventing fuel leakage. So I guess it is supposed to rattle.

If not, the part no. is there, just PM Rufe.

Top man, thanks. Do I need it or can I just do away with it because the rattle is driving me nuts?

[Dangerous Dave]

It won't do anything to the system if you bypass it, as its just a rollover valve, but it is there for a reason.

Thanks, I'll just keep it upright once I remove it.

Thanks, I'll just keep it upright once I remove it.

Why not just buy a new one? Can't be that expensive...afterall, it's not there as a fashion accessory ;)
