Fuel pressure regulator

[LongBaz]

Do you know if this will fit on the Chimaera fuel rail. I need to upgrade mine.
Thanks

Yes they are the same fit but up the pressure to 3.5 bar.

I fiited one to mine when i had the 5ltr.

Thanks for the reply. I need 3.5 for my turbo install

Not sure they will handle boost, certainly not decent psi.

Several have had problems with the standard regulator closing completely when seeing a decent amount of boost causing the fuel rail to over pressurise and therefore over fuel.

For a forced induction setup i think you will need something designed for boost.


Boostedchim makes mention of the regulator he used in this thread. from a 944 turbo. Fits the standard fuel rail.

Had a quick read around this and the 944 turbo one in that thread is rated at 3.0 bar I believe - there's a good thread here with all the different part numbers and the bar rating

"They are a Bosch reg and the 0 280 160 defines the fitment. The last 3 digits the pressure rating.

3.0 bar 0 280 160 258
3.8 bar 0 280 160 287
3.5 bar 0 280 160 263"

That's a great help, thanks.

The 3bar genuine bosch turbo reg seems hard to get hold of, I always struggle (as with all things these days beware of cheap copies) .. but I've also successfully used the 3.5bar cerb regulator up to 12psi with no problems .. not run it over that but it's been consistent and reliable 1:1 above boost pressure up to 12psi. Hope that helps.
