Leaks in Fuel Pressure Regulator Block in a Land Rover

Leaks in Fuel Pressure Regulator Block in a Land
Rover
2
A common fault in diesel vehicles is the leakage
of fuel from the fuel pressure regulator block.
3
In a Land Rover, it is mainly caused by a
deteriorated diaphragm or damaged seals within
the block.
4
So, it is good to be aware of the symptoms,
problems as well as the solution of the leak in
the fuel pressure regulator.
5
Symptoms of a leaking fuel pressure regulator
6
You will find fuel leaking down from the fuel
pressure block at the driver's side rear of the
engine, which gets collected on the bell-housing
or the starter motor.
7
A strong smell of diesel under the hood is also a
clear indication of a failure in the regulator.
8
When you notice that fuel leaking from the hole
in the fuel pressure regulator then be sure that
the diaphragm in the unit has failed.
9
What is the problem?
10
The function of the fuel pressure regulator is to
keep the fuel pressure at a constant 4 bar
pressure.
11
The diaphragm within the fuel pressure regulator
deteriorates, causing fuel to leak from the fuel
pressure block.
12
It is important to figure out whether to replace
the complete block, the pressure regulator unit
or the O-ring seals of your Land Rover.
13
How to fix the problem?
14
The economical way is to only replace the
components that fail within the fuel pressure
block with improved components and not replace
the complete block.
15
Most often, either the fuel pressure regulator
or the o-ring seals are the components
responsible for the leaks in the block.
16
So, choose the best solution that provides a
cost-effective alternative to the replacement of
the complete fuel pressure regulator block in a
Land Rover.
17
Do it safely!
18
You must ensure that there is no naked flames or
smokes around exposed fuel.
19
Support vehicle on axle stands, use wheel chocks
and ensure in gear with the parking brake
applied.
20
Always wear gloves and eye protection when
working with fuel, oils and grime.
