107.045 380SL 1982 Fuel Blues & Fuse

Hello all,
I really enjoy reading your posts and thanks for all the useful information.

I have a 1982 380SL 107.045 and am in need of a fuse diagram.
Panel was missing when I got car.
Recently, left side cluster (oil pres, gas gauge, and temp) all went out at once.
Would these be fused or tied to a common relay.
FORMER friend of mine was "helping" when vehicle was RUNNING and he removed all of the relays (4) one at a time from fuse panel in passenger kick plate to check for corrosion!, while I was under hood lubricating fuel linkage.
Anyway, shortly after, I noticed that the left cluster was out, any ideas there would really help.
I am also trying to figure out a fuel issue.
The car had sat up for about 4 years with half a tank.
It started and I topped off tank and then added a bottle of HEET to dissipate any water and a bottle of Lucas Fuel Injector cleaner.
It will idle in park like a dream (well, maybe a dream with a slight miss!) however, when I put it in gear, it wants to sputter and die.
If I EASE the pedal down from dead stop it will "catch".
Also, no apparent trouble at highway speed. Somewhat of a miss and I have some exhaust noise. (Bad converter?)
Thus far, I'm stumped.
I knew fuel was suspect so disconnected the fuel line input to the fuel distributor and pumped about a quart into a bottle.
Saw a little bit of water, very little but it was there.
I then replaced the fuel filter and plugs. Saw some brief but encouraging improvement but then it reverted to old sputter bug from take off.
Also, interestingly, it starts with first turn of key, every time and like I said, it will idle in park or neutral all day.
It's just when its under a load that the problem is worst. I also replaced coil.
ANY help you could provide would be greatly appreciated.

Thanks!

Post your email address and I'll send a fuse chart.

I think maybe you should drain all the fuel and start again fresh.

ISSUE: Recently, left side cluster (oil pres, gas gauge, and temp) all went out at once.
ANSWER: Bad ground common to all effected circuits.

ISSUE: Fuel issue, the car sat about 4 years with half a tank, disconnected the fuel fuel distributor input line and pumped about a quart of gasoline into a bottle, saw a little bit of water, very little but it was there.
ANSWER: The system is contaminated with varnish, and water/rust = the new filter is plugged with sludge.
* Drain everything from the fuel system and tank.
* Flush the body mounted steel lines with carburetor cleaner, followed by fresh fuel.
* Remove and have the fuel tank professionally cleaned.
* Replace the filter again.
* Fill the tank with fresh fuel.
