Info
Griffiths manufactures Porsche 964 Fuel Lines for 1989-1994 Porsche 964 C2 and C4. The Fuel Pressure Regulator to LH fuel rail and Fuel Pressure Regulator to RH fuel rail are both available for purchase. Our lines use the latest SAE J30R9 hose which has a higher resistance to standard petrol fuel, biofuels and alcohol fuels such as E85. Griffiths fuel lines also have a lower permeation rate compared to original stock hose and older J30 specs. Our hose material is EPA Certified and CARB certified (C-U-07-17). We use steel components with a protective plating passing EU recommendations. Griffiths fuel line fittings conform to DIN mating standards. We also pressure test every fuel line. Unlike competitors, we do not incorporate used components. All components are 100% new.
Why upgrade your fuel lines?
The Porsche 964 was introduced in 1989. You don’t have to do much math to figure the original rubber fuel lines in your Porsche 964 are about 30 years old. So how long can rubber last? That depends on the compound and the construction of the hose lines. High temperatures and ozone levels also stress out fuel lines. The point is your original fuel lines have probably reached their limit. When they fail they could spill fuel in your engine compartment, which sits right above the hot exhaust system. The tell-tale-sign of failing fuel lines is smelling gas when the heater boxes are open. You’re better off avoiding an engine fire. It’s time to upgrade your fuel lines!
Replacing your fuel lines
You can have your mechanic do the work or you could do it yourself one day on a weekend. For a DIY-er it takes 10-14 hours depending upon your pace. One fuel line could take a few minutes while others could take hours. The difficulty of the lines varies by location.
