Welcome to brickboard. Valkommen, yes?
A service center that is Bosch qualified may be able to force fuel system solvents under pressure through the fuel system removing varnish and gum, at quite an expense.
No, unless you have very special equipment and chemicals, the average home mechanic must never dissemble the Bosch K-Jetronic fuel distributor.
Even using something like a fuel stabilizer in higher concentration, that is run through the fuel system, can fail over some years, causing varnish and other junk to prevent fuel distributor function. You can send it to a Bosch-certified service center, and they may be able to reassemble your fuel distributor at quit some expense.
You best bet, if you mean to let the Bosch K-Jetronic-equipped Volvo sit for years, it to clean all around the engine bay, break the fuel lines open, and bag the thing in some anti corrosion spray compound, under utterly sanitary conditions. Seal the open fuel line ends with bags or something. Though that's risky.
Else, you find a professional service center that can properly prepare the fuel system for long term storage without having to break open the fuel system. Very expensive. Same thing as professional auto racing organizations do.
With fuel sitting and gumming up teh works, or worse, rusting, you have to consider faults in the Bosch K-Jetronic electronic fuel pressure regulator that sites someplace near the K-jet air / fuel control unit. Also, corrosion can form on the injector interior. Anyplace where fuel sees metal inside the K-Jet system, from the fuel tank to injector.
The ethanol in gasoline is anhydrous and draws moisture where ever it can. As the fuel ages inside that fuel system, the hydrocarbons and alcohols deteriorate, and water can separate away, make contact with anything metal, and let the corrosion begin and the gumming vanish futz up th works.
Okay, lettuce, turnup, and pea. Oop. No. lettuce see hhhwhut Google can of with that Bosch part number of 0 431 000 073.
Welp, that did not work so well. Is the part number correct? That is not a Volvo part number. Though both parts number should be on that CIS K-jet fuel distributor.
At any rate, search eBay. You may be able to find innumerable fuel distributors. Yet, you are on notice the same problem may occurs in the fuel pressure regulator innards and the injectors.
Oh, I see you saw eBay. I'll guess that is a no. Fuel delivery rates for Turbo are higher.
Do your research.
Questions?
Hope that helps.
Bosch K-Jetronic CIS in a 1975 Volvo 244 & a 1975 Volvo 164? Weird, huh? Saw K-Jetronic on a Volvo 164 with the B30F. That was cool.
