Factory EFI
I'm pulling down my engine to sort out a serious knock and having fun with finding all the extra parts involved with the factory efi system. What is
concerning me much more than the internals is having to replace practically all the pipes and tubes that have deteriorated over the past 30 years so
what I'm after is does anyone have or know of a comprehensive guide to all the pipe/tube connections? The workshop manuals I have only have very
limited details and I've not found much via google either so any ideas please as even though the attraction is to go back to carbs to keep it simple
I really would like to keep the car original.

Mine is one of the last convertibles (October '79) so the right thing to do would be to keep it as original as possible even though "more
power/carbs/even Subaru!" have passed somewhat briefly through my mind. But to keep it original means basically replacing all the pipes to things
like the charcoal canister or the fuel pressure valve (that I found to my surprise down the back of the fan housing when searching for one of the top
engine mounts ) let alone all the smaller vacuum pipes so the
upshot is if I can get a detailed diagram or guide of some sort it would be very helpful - a lot more helpful than the tiny supplemental parts in my
workshop manuals. I did take photos of everything before I started for this very reason but I was more (stupidly) concerned with the electrical side
of things.

Just got down to the nitty gritty of pulling the whole thing to bits and I'm amazed how much the engine differs from the standard 60's and early
70's engines that I've pulled apart in the past or at least the ancilliary parts. The exhaust for example has 7 seperate parts that bolt together to
it, the tinware is different. There's a sensor that fits to the case that obviously picks up from the back of the flywheel but there's just one wire
to it that connects to a gizmo that sits on the back of the fanhousing - no power, no earth!!?? Any ideas? I've had a case before with the sensor
fitted but the cable had been cut. The good news is that the engine doesn't look like it's been touched before so 30 years of grime will be cleaned
away before it ever goes back. I'm wondering if there's any improvements I could make before putting it back, such as better camshaft or c/w crank
considering I want to keep the original FI now, any ideas would be welcome

Those 70s Fuel injected mufflers are certainly complicated setups compared to the old garden variety peashooter muffler/heaterbox setup
Is yours the American version with the cat?
they are even different yet again.

It should have the cat but I had to get a new muffler made a few years back so that was deleted plus the exhaust recirculation valve has also been
blocked off. The whole exhaust looks in pretty good condition though so I'm happy about that

Any clues to the sensor behind the flywheel?

My 74 LBug had the sensor behind the flywheel, it is only used by the diagnostic plug. All the L-jet diagrams I have seen don't show that sensor, so
it's not involve with the injection system but is used to check the timing/dwell
