When you add a FMU (Fuel Management Unit) to your Porsche 928, you will attain fuel pressures as high as 120 psi under full boost.
We have found that the stock fuel return line out of the fuel pressure regulator can burst under these conditions (especially if it is old) and spill fuel all over the top of the engine.
To prevent this, replace your fuel pressure regulator fuel lines with our High Pressure Fuel Line made just for this purpose. It is 7.5mm metric in size and an exact fit to your 928 regulator and has:
- working pressure rating of 215 psi
- a test pressure rating of 430 psi
- a burst pressure rating of 850 psi
Price is for one meter of this hose: Imported from Europe by us for you. One meter is enough to do both fuel pressure regulators on your 928, and have a bit leftover. Additional lengths are available if you need more - call us toll-free at 877-FOR-928M.
