Fuel lines in tunnel
 

How much fun am I getting into replacing fuel lines in the tunnel with the car all together need help

It’s easier with the engine/trans out of the chassis, gas tank out and front suspension dropped down.
The first few inches of rubber hose off the fuel pump is what leaks in my experiences.

The hype is overblown. I got Len’s kit with the special pull through fitting. It was a 1hr job max.

Maybe with Len's Kit. I replaced with stock and it was a ***** and more.

Trev,

If you use Len Cummings (BoxsterGT) replacement tunnel lines, it is much easier. After removing the lines going to the engine bay connected at the rear of the tunnel, you connect the front of the new tunnel line to the back of the old tunnel line with a connector that Len provides. Then you pull the old line out from the front of the tunnel which pulls in the new line in at the same time. When I did this job, I had to remove the passenger seat, the center console, the shift coupling cover plate and pull the tunnel carpet back at the front and rear to gain access to the tunnel access holes. On my car there were metal tabs at the front and rear that were bent up to hold the tunnel lines at the top left front and rear corners inside the tunnel, which caused my lines to get hung up. It just depends on how tightly the tabs were positioned when the car was built.

You will need to remove the transmission cross member and support the front of the transmission with a jack stand, etc. At the front I had my steering rack out (for maintenance) which makes front access much better to pull the lines forward. Others had done this job with the rack in place. There are rubber grommets installed at front and back tunnel penetrations that must be removed prior to pulling the tunnel lines. The easiest way to remove them is to push them into the tunnel and then pull them off the line (grommets are split) through a tunnel access hole. Otherwise you would have to use a pick to pull them out from outside the tunnel. You will need to buy replacement grommets.

Tagging this thread because this project is on the short list for my 82 SC. Sounds like Len's kit is the way to go. I appreciate all the info, tips and tricks provided so far.
