I think I replaced my Fluos with LED's a few years back, but honestly can't remember. The fact they come on may indicate the latter.

 

The cuttoff is for the Idle and Progression (just off idle) . It does not affect the primary fuel supply.  Ford did not fit them so they had a screw in blanking plug. 

my money would be on the fuel cutoff solenoid

Ahh, if you drive a petrol engine and the alternator cant keep up then it will eat the battery. That could easily explain your 5v The alternator and oil light should both come on when you turn the ignition ( to show they are working) and then not be on when driving. Although if the alternator isn't...

I will have to take a look at the circuit diagram to see where the commonality it on the dash , the chances of the guages failing at all is low and all at the same time would be unlikly unless an error caused them to fail. 

Has it got the stock air filter system
Has it only occurred in the last 3 months
Will it not start after a prolonged crank
Any other running issues [hunting at idle]
Basics been done, new filter. Timing, plugs.
Vacuum capsule in dizzy holding air.
Is the fuel solenoid energizing .

i was chatting with copilot about this, and a full re-engineer with just a modern microcontroller and as few simple components could replace all the analog components. it seemed to have a fair idea of what was needed, what inputs are provided and the PWM drive for the ISCV.

I ran the golf without it for a while , can't remember if it was on the original 1.1 engine with Solex or after i fitted a MK2 1.3 with the 2E3 , can't remember the time line .. eventualy got a Polo GT EFI . If your worried about over fueling , fit it If your not worried about over fueling , ditch i...

the picture from here https://www.coolairvw.co.uk/search/?search=2e3 shows 3 ports which is feed outlet and return. The unit is a basic presure regulator in effect. A faulty one can cause fule starvation ( I chased a fault for months loosing power going up hill in a mk1 golf till i just bypassed it )

did the switl pot have a return?

so an undrilled casting

Entirely dependant on many factors. if it does not get the opportunity to run regularlty it may seize up. if you live in a damp environment it may get rusty. 

is there no blanked port for the return?
 

who were you going tosend it too as the last specialist in pierburg no longer operats AFAIK
