rulls of cleanness while working on fuel system

[Konstantin Bogach]

Hi listers.

I am taking apart fuel distributor. How can I protect all open fittings
from dust, sand (dense mixtrure of oil and sand in many places around)
and any kind of contamination? What are general rules? Does rubber plugs
exist for these purposes? Can I find them in local parts store?
I will appreciate any recommendation?

Thank you.
