_leon_ 0 Posted December 28, 2005 I was inspecting the fuel lines off the fuel rail today after noticing a strong stink of fuel lately. On a cold start (first of the day) I checked over the engine whilst it warmed up - what I noticed was: 1) there was a weird soft hissing noise (like air escaping under pressure) from around the back of the block... 2) I could smell fuel coming from the pipe between the right hand side of the fuel rail leading to the switch unit 3) the catch tank (which was smelling very strong indeed) was about 1/3 full of what seemed like petrol after installing it only 2-3 weeks ago (its a Gwerks tank so hopefully some of you know the size of it - its pretty small). A boost return kit has been fitted at the same time as the catch tank and I know the rocker cover gasket needs replaced as theres oil down the back of the block from that seal (probably the hissing sound). For the meantime a new fuel pipe is on order along with the clips (anyone got the part numbers etc for the self tightening clips - VW seemed very hazy on those) and I've checked over the connections around the breather to the catch tank etc. Any help on what to do would be great :) Quote Share this post Link to post Share on other sites
