When I took my 06 S3 to the dealer for the TORS tune the gas tank began sucking air when I opened it. No problem, the mechanic probably hooked the hoses up wrong. I dragged my feet about fixing them until I read Devious2xs post about how hard it is on the fuel pump. Today as I removed the gas tank there was a similar sucking sound. The hoses were hooked up right, they were just pinched. I tried to improve the spaghetti hose mess at the water pump but there's not much room to feed everything. Also, some of the hoses are too short to thread through the half dollar size collector ring under the engine. Could this be a problem or am I making something out of nothing?
