Took some time during lunch today to install the stainless heat boxes I ordered a while back from EPM.AV. These are real nice and have a ceramic gasket to help stop any heat being transferred between the boxes and the firewall. They also came with a high temp silicone sealant to make sure no gases leak by. I also ordered some AN fittings and tubing to add the AFP purge valve return and replace my Aeroquip hose at the fuel selector.
