Hi all where would the best place be to get hold of a fuel pressure regulator for a 1992 907ie in the UK
Cheers re Alistair

I don`t know but there`s a choice of aftermarket fuel pressure regulators (adjustable or not) you could adapt.
According to what was posted on this forum the fuel pressure is 3 bar. (I guess RP7 3,0 is stamped on the housing of the fpr)

PS: the Weber fuel pressure regulators of the Lancia Integrale is RP7 2,5. The one of the Sierra RS Cosworth is RP7 3,5 so they are not the correct ones.

Thanks for the replies just a question there is a small pipe routed from the regulator to the the intake what is its purpose, only aftermarket regulators I have seen haven't got this outlet and have only a supply and return. Thanks again re Alistair

from the wsm

rising rate fprs:

At times, in demand situations such as high acceleration, the engine needs more fuel. Rather than program a second set of fueling parameters to deal a special situation, one can take another route to the same place by using mechanics rather than ECU programming. In this case, these regulators are used. By having it react to engine vacuum (hose to the plenum), you can have it increase or decrease the fuel pressure on demand. In doing so, you are injecting more fuel though the injector duration remains the same.

Oddly, the connection to the manifold isn't used on any later injected Ducatis. It's just left open to the atmosphere.

a little bit offtopic but interesting:

what I found:
Bosch 0280160202
(It should be verified that the hose connections are the same to be sure this is not a dual outlet or whatever! So this is just a lead to pursue. Connectors are for 8mm fuel lines)

another option may be the fpr of a Volvo 850/S70/V70 which is 3bar as well.
This would require the housing, too.
I`m sure there are many others that could be used/adapted.

Of course the original part is still available but it has its price.

why didn`t anyone point out that the picture in the wsm actually shows the wrong kind of fpr? It shows one with an IN, RETURN and OUT (+ vacuum) hence a fpr that would be positioned before the injectors.

I was looking at the parts catalogue of a 900SSie and noticed the fpr was actually behind the injectors hence has only an IN and RETURN (+ vacuum) and that it is the same on the 907ie.
It is 3 bar as well. So it would be a suitable option. The fpr sits in a housing (830.1.091.2A - http://www.desmoduck.com/search.php?par ... 0.1.091.2A) other than i.e. on the ST2 where it`s in the whole tank assembly where the fuel pump and filter is.

or cheaper

The last two posts are still an option I think but one would have to reroute the fuel hoses a bit and block the exit of the second injector so that would only be a last resort solution.

Thanks for all info I haven't had time to do anything with the bike yet, but I also found that the fpr off a sierra rs cosworth from the 1980s looks a fit and there are aftermarket adjustable pressure ones available so i might investigate further, cheers all

if anyone in the US needs a spare one:
