Replaces Porsche part number 944 110 198 01 for Porsche 944 '82 to '85 with the M44.02 and M44.04 engines. 2.5 bar base fuel pressure.
Replacement for Bosch 0 280 160 214

Direct replacement for the OEM Bosch fuel pressure regulators on the Porsche 944 and some other makes and models.  Most of these regulators are original and now nearly 40 years old so they are prone to leak or fail causing all sorts of running and tuning issues.

To suit the lower operating fuel pressure of the 3.2 Motronic, we use an adjustable fuel pressure regulator.  This simple and elegant design uses steel O-Ring boss sealing adapters to the manifold. 

Easily replaceable fuel pressure regulator.

Spare outlet for fuel pressure gauge or sensor.

The adjustable fuel pressure regulator has been tested with Bosch 044 fuel pumps, but the upper limit of fuel flow rate has not been tested.

Kit Includes:
Porsche 944 OEM fitting kit - SPA Adjustable fuel pressure regulator
Fuel pressure regulator body x 1
2.0 to 5.0 adjustable fuel pressure regulator instead of fixed regulator x 1
Adapter fittings to fit OEM hose and fuel rail ends x 1
Hose Tail fitting to fit factory return line x 1
ORB Plug x 2

Applications 
This kit must use the adjustable fuel pressure regulator as Bosch does not produce a standard 2.5bar pressure regulator in this form.  

Please Note
We have also developed fuel pressure dampers for the 3.2 and 928 engines, check out our site for the product details.

The fuel pressure regulator needs to be adjusted and set on the car after installation to ensure the operating conditions meet the factory specifications.  A fuel pressure gauge and fittings to adapt to the factory fuel rails is required to be able to complete this procedure.  The regulators are not shipped pre-set to the 2.5bar operating pressure.

We also list the 944 fuel pressure damper as a direct replacement.

Balance shaft delete kit.

To help remove all the balance shaft belt and ancillary products on 944/968 which is only way to make the engine run smoother (After you’ve removed that stuff these bungs to plug up the holes on the engine, so it does leak from where the shafts used to be).

So, engine will still run without all that balance shaft belt and ancillary, maybe a bit rougher but will save a bit of engine power not having to drive all that stuff and engine weight. (Crankshaft/Camshaft timing is on a separate timing belt on 944/968)
