Hi guys, I'm trying to diagnose if i have a slipping clutch. I've replaced my clutch just under 12 months ago and haven't really given it much grief. Most people say go up a hill in higher gears and you should see it slip. Mine grips fine in this circumstance. My problem is in 2nd gear, when...

Hey guys, I did a search and it doesn't have the answer i need. I bought a SARD AFPR with 8mm fittings. I notice you guys use 3/8" hose in the AFPR kits. Is it fine to use 5/16" hose to the fuel rail?
