I replaced all the soft rubber bits in the engine compartment as well as from the fuel pump to the tunnel with SAE Fuel Injection hose from my FLAPS. Left the hard plastic lines in place. I cut the swage off with a dremel and used hose sized to fit the barbed end. FLAPS did not carry metric, the SAE sizes were close enough to work. Used FI hose clamps also supplied by FLAPS to secure the connection. I did double up clamps where space permitted. Total cost was <100. These have been in trouble free service for 8 or 9 years, 50K miles, lots and lots of track time.

With one exception. I did not use FI line for the tank to pump connection (gravity pressure) - just standard SAE rated low pressure fuel line. It showed significant cracking after 2 years. I suspect alcohol in the fuel settling out and concentrating at this low spot over winter storage. Replaced it with FI line, and no issues since.
