Porsche produced the 914 1.8 for two years (74-75) with two different FI. Every time I talk to someone regarding the l-let, they are quick to point out two things. First, the l-jet is the best FI for the 914 (also the basis for all future FI, used on the 912 2.0L, AFC vs MPC, etc) and it hates vacuum leaks! Which is great? But does not address the fundamental lack of information for Porsche 1974 and 1975 914 regarding their l-jetronic fuel injection system.
I have searched high and low for information regarding l-jet. It has been hell trying to get basic information that in the d-jet world widely documented considered simple and widely available. I dedicate this thread to the “Full Disclosure” -- l-jet revealed! I am hopeful that we can put together a thread that can actually help 1.8 owners The glove has been thrown… Regards, James |
