Griffiths manufactures Fuel Lines for the 1984-1989 Carrera 3.2 litre engine. 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. 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 911 3.2 engine was introduced in 1984 and incorporated the new Motronic engine management system. Previously the engine used CIS and prior to that carbs. You don’t have to do much math to figure the original rubber fuel lines in your 3.2 are over 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 replace the 3 primary Porsche 911 Fuel Lines attached to the engine, or you can do it yourself one day on a weekend. Most Porsche repair shops take on this job when its time to replace a transmission clutch (or when the engine is dropped) because it’s easier. The job could also be done while the engine is in the car. For a DIY (do-it-yourselfer) it’s a 6-8 hour job with the car on the ground. You don’t need special tools, but we do recommend a mirror. Placing a mirror in the forward section of the engine compartment allows you to see what you can’t see normally. You’ll be removing the auxiliary heater blower motor assembly on the LH side of the engine, and the air filter box and RH intake manifold. Griffiths offers all the parts you need to do the task with our “911, 3.2, Engine Fuel Line Set, Complete, plus RH side manifold gaskets and fuel filter” kit.
