I'm getting poor pressure on my Frontera fuel rail, with little or no fuel getting to the injectors. I've replaced the pump with a Senator B 3.0 one, and I can hear it running on startup, but the engine starts but not run after a few seconds. I suspect the regulator but not sure; question:

is the fuel line input just under the regulator on the Frontera rail, or is it the one on the rear of the rail wtith the 17mm bolt? the Haynes manual I have is for the GTE but i'm running the Frontera rail on a 2.2 Carlton head with big valves, sitting on a 2.7 bottom end.

its doing my brain in, so need advice, PLEASE..

Just to keep it simple, the pump supplies the rail direct and the pressure reg should be on the outlet returning to the tank. 

What pressure are you getting at the rail?

I agree, you need a test gauge to check pressure...I have a fitted gauge under the bonnet, which help with roadside breakdowns such as  blown fuel pump fuses etc

so the fuel in is the 17mm nut end end of the rail with the return under the regulator,  on the Frontera, Snowy?

i'll purchase a guage asap thanks.

and yes Buz, please provide photos of the rail with fuel lines attached.

cheers

and thanks Mick, i tried swapping round the flow and return pipes under the bonnet, but it made no difference.

Hope these help . Let me know if you need any more .  The manual says pressure should be approx 3 bar

Does this help? Ignore it says Bosch D.

The Frontera fuel rail set up is so much superior to the standard Manta one and safer in regard to leaks over a hot exhaust manifold !

fantastic picture H; much appreciated. one drawback of the rail compared to the Manta one, is you cant replace the regulator with an adjustable type like a Sytec/FSE.
