I have been experiencing a weird issue over the past few weeks, the beetle starts from cold like a new car. But when I drive and it gets good and hot say 5 minutes or 25 minutes, if I stop for a short time and go to restart it struggles. I think I know the cause and it is vapor lock. When I put the new gas line from the filter out to the pump it was a bit long and quite close to the exhaust. I think<\/em> it might be starving for gas. If I push start it, it starts right up. <\/p>\n\n\n\n

So my fix was to cut the hose 2″ shorter and move it to the slightly higher hole in the firewall. The first test run was positive. I’ll go on a little longer test run tomorrow. <\/p>\n\n\n\n

This is what it looked when I started. <\/p>\n\n\n\n

In my beetle there are two holes in the firewall, it was going through the lower hole, so I put a grommet in the higher hole to avoid friction wearing the line down and to get it up away from the exhaust header. <\/p>\n\n\n\n

As an aside, these Stahlwille 12975 fuel line clamps are the best I have ever used. They are available from KC Tool here: https:\/\/www.kctool.com\/stahlwille-12975-fuel-hose-clamp\/<\/a> <\/p>\n\n\n\n
