Although my car (1963 3-Litre) has been running recently, it sat for about 10 years before I got it last year. The guy who cleaned the carburettor told me that I need to remove the tank and clean it, and either clean or replace the fuel lines. He said the carburettor was "full of shellac."
This seems a tedious, unpleasant job, but I'd like to hear advice, suggestions, and be referred to previous discussions on the subject (I searched but didn't find any).
Thanks, Gordon.

Just a note--I'm able to find some posts on the subject when I look manually, calling into question my searching skills. Suggestions welcome nonetheless!

Tank can be removed to swill it out of loose stuff with petrol or paraffin (kerosine) - similarly with the fuel lines or it may be easier for the line just to be replaced with modern nylon or copper/stainless tubing.
Carb cleaner will remove the gum in the actual carb (even cellulose thinners will deal with it) - in HD carb of the 3 litre there are really narrow drillings which will block up.
Same comments apply to the P5B too
This is becoming a problem with modern fuels in the UK and if extra additives are poured in as well which are unnecessary in both P5 and P5B's it makes it even worse

Thanks Phil. Are there fuel lines available for these cars, or does one buy a roll of it? U.S. parts stores aren't very good with British stuff, so any sources welcome.

My car also sat in a garage for 16 years, I did give the carbs a good clean up but that was all, touch wood its been ok since 2003, as Phil says clean the carbs and then why not see how it goes.

No fuel lines - buy the rolls - these are easy to get either metal or nylon

Some progress to report. I got the tank out, and will be reading up throughout the week on the cleaning process. I'm sending the fuel pump to be rebuilt professionally (I have a history with these pumps), and the carburetor is now clean. I'm have a devil of a time getting the clips that hold the fuel line along the underside loose, but have sprayed them with penetrating oil. Once I get the line out, I'll clean it with the help of a friend with a compressor, figuring I have nothing to lose there.

I'm sure you guys are aching to know how I'm getting on with my fuel-system refurbishment.
I was able to get the line out, cleaned, and replaced, am hoping to use it unless it springs a leak.
The guy who's rebuilding my pump said it's the worst (dirtiest, most gunked-up) he's seen,filled with grey sludge, calling into question the state of the fuel tank. I started cleaning that, but have bought a reportedly clean one from a P5B. I'll treat that for surface rust and I should be on my way once the pump returns from the North Pole.
