Drill gascolator doubler to firewall.
Deburr. Dimple firewall.
Cut throughhole for fuel line.
Need to countersink and prime the doubler, then that's all ready.
Then the gascolator mount will be in the critical path.
Received an order today from MPJA. The led indicators I will use were in the order. I think they'll work out just right. I'm using the 10 mm square indicators. I tried them out, and they're perfect for the application.
I'll have red for the oil pressure switch, yellow for the B&C voltage monitor, green for aux fuel pump, and blue for the heated pitot.
