(MPC) L jet (AFC) is the superior system and much simpler than the d, but was only available on the 74 75 1.8 and 2.0 912e models. The systems are totally different one using an air flow meter and the other using a manifold pressure sensor, for starters! |

Yes. Because of its simplicity, L jet IS more reliable. One needs to watch the air flow meter for lean backfire when starting cold, and keep the dual relay clean, but beyond that it is great.
The caveat is that since the system was only made for two years and that 75 adn 74 are slightly different (seven pin vs six pin air box and harness) that finding used parts for the system would be hard.

I want a system that will last long on my 1.7. i would not say L:-jet is more relaible nor has more simplisity. the L-jet has a very delicate air flow meter, (back fire can ruin it) L-jet is hyper sensitve to vaccum leaks. although the 914 L-jet is more modern, than D-jet, the D-jet system was more sorted out by the time 914 used them, the L-jet was new then, not as well developed. the D-jet is extremely simple, with less complex moving parts (pressure sendor verses air flow sendor) D-jet is not hyper sensitve to leaks like the L-jet is. I'd stick with D-jet a well proven system on your 1.7 enigne. everything will fit and be right, not some bastardized set up. |
