Fuel pressure regulators
Discussion
Can anyone make and reccommendations as to fuel pressire regualtors, specifically for a 51psi/3.5bar injected Rover V8?
I'm a bit wary of the FSE offering becasue i know of a few that failed last year and dont want the same to happen to me.
A standard RV8 35psi one is no good obviously.
Anythougts on the Weber/Alpha billet offering?

chassis 33 said:Whilst it may not be quite the answer your looking for,mine has been crimped to give the higher pressure required for fuelling the mods i have with my still std. injectors.Its pretty common practice apparently,and mines been like this for a year now with no problems whatsoever.

I'm a bit nervous about crimping pipes to that the diaphram sees and extra 50% of pressure. IIRC when you get above about 40psi (I think) on the standard injectors there is too much pressure for the injectors to open, so I would be suprised if the diaphram is seeing anywhere 51psi even with the crimp.

chassis 33 said:I think MA said something like 3.3 bar from memory,is where you start to get issues with unopening injectors on these cars.What mods have you got,and just how much fuel do you need?Mine runs at 3.0 bar from memory.I'm a little confused by the statement above.Your not crimping any pipes,your crimping(squashing a little)the regulator itself.Cheers,Mike

Ah ok, just confuzcultated by the description. Don't worry, I've seen some people run with a set of mole grips crimping the return to get the required rate and got rather worried!
It's to run the Bosch injectors that were specced on the last of the Disco II's with the Bosch/Thor setup and also (I believe) some of the GEMS setups, they run at 51psi with the regulator built into the fuel pump, and the fuel rail is a dead end system; hence to run that manifold base I need to make some alterations.

Out of interest. What method of fuel control are you using ??
Just because one setup uses 51psi, doesnt mean every one does. I assume you must be using the entire fuel setup, including ecu etc ?
If you have some form of fuel control ( ie programmable ecu ), you need to run whatever fuel pressure works. Nothing specific.
