All,
I've been having a blast driving the Birkin to work and some quick pleasure drives. I've made a few adjustments to the Emerald map to get rid of a rich running condition on low/no load sites and fixed a couple moderately lean conditions at some higher load/rpm sites. One thing I haven't been able to correct is a fuel smell from the back of the car that I can't trace to a visible leak. I have a Fuel Safe fuel cell that I installed and plumbed the same way the original Birkin tank was installed. Here's a couple pictures of the installation and fuel vent cannister. The small filter is actually hooked up to the rear end breather.

I'm seeing some fuel in the clear hose from the check valve (on the lower left of the 1st picture) going to the fuel vent cannister after driving. Since I believe this is a roll-over shut-off valve, I think that could be normal with a full tank. The fuel has gone over the top of fuel cannister and rested in the bottom of the loop but when I removed the fuel vent cannister, I didn't see any fuel collected. What I was wondering is if I'm doing anything obviously wrong that would be causing the smell. I was thinking of turning the check valve around 180 degrees, running the vent line up the left inside of the rear bodywork, back down again after a 180 degree loop and then continue the existing route to the fuel vent cannister. I was hoping that might keep some of the fuel from making it to the cannister. I was also concerned that the fuel return that's hooked up to a bulkhead fitting in the fill plate was causing some problems when the gas was being dumped back into the fuel cell, so I made up a 3/8" line to take the fuel closer to the bottom of the bladder between a couple of the foam blocks. Here's a pic of the fill plate with line:

Maybe I have a leak that I haven't located yet, but if anyone has some advice on my installation or helpful links I'd appreciate it.
Thanks, Bruce :7drive:
