We need a fuel regulator for a 1992 5.3 XJS. It is on the right side fuel rail. (only one on this engine) Secured to the rail with two bolts. Last six numbers on the part are
480208.
Also need the Solenoid Vacuum Valve
Electrical Temperature Switch, Located on the underside of the left bank fuel rail.
and the Vacuum delay valve. Located in the vacuum hose circuit near the Fuel regulator.
The problem with the engine is that it starts hard when hot. Fuel regulator seems to be returning fuel to the tank and cant hold pressure when the engine is shut off.

 

If you're running an old jag the JDHT parts catalog is your friend. You can get the part numbers you need then Google them and see what comes up....and go from there.

The fuel pressure regulator is NLA from Jaguar and I know that others here have searched for one. Or searched for reasonable substitutes. Not sure what they've come up with

Others will chime in with more info.

Thanks for the reply. looks like some sort of adapter to use one of the commonly available regulators needs to be created. Or a bunch if Webbers.
