Thread: Fuel Pressure regulator problems on 2.2 duratorque (Puma) engine.

Diagnostic report points to FPR.

Has anyone had problems with this in their Defenders?

Suggested costs vary between $700 and $2800...ouch.

The Ford genuine pricing for the suction control valve is about $480 and the pressure relief valve is about $300. There is a part that attaches to the pressure relief valve that is about $30. You can get the SCV for as low as $130. Its common to about 30 vehicles. Dont get sucked in to being sold a fuel pump. Best to replace all 3. Budget $1000 with labour. Once the pressure relief valve is popped it will never seal again

Is this problem permanent or could it occur occasionally and fix itself within seconds?
I ask because my 2.4 had a 30 second loss of power and then came good. So I'm not sure if this is the cause. Any thoughts?

You need to do a diagnostic test to know what faults are logged. The fuel pressure relief valve will show up as a fault with the fuel rail pressure or similar faults. It usually pops due to a faulty SCV. Once they pop they never properly reseal and will open under full load triggering a fault.

Thanks. It's due for a service and I'll have it checked.

Have you changed the fuel filter ?
Have you checked the fuel tank breather pipe isnt blocked ? How long since you last filled the tank up ? You may have got a bad batch of fuel.
