P&A,
You really need to look back through postings! I recommended reading post 83 to AnFi and he recommended it to others.
Take a look at post 1471 onwards on the Glasgow thread also.
I can't remember anyone suggesting transfer pumps cavitateing, I certainly hav'nt, that would be fairly normal.
My concern with the 135 fuel system is fuel not getting to the supply tanks and being trapped in the main. Transfer pumps spitting fuel into the supply tanks, and the engine pumps then not being able to keep up with demand.
If fuel is being intermittently pumped to a hot turbine, this in theory could cause popping banging etc. on some turbo props when doing a wet start you get this effect.
Hope that's clear, I know I'm not very articulate.
