Primer fitting
Primer fitting
What is the correct fitting that should be installed at the intake manifold at the end of the 1/8" copper tube coming from the primer. My C90 came out of an Forney Ercoupe and It has the restricted opening .030 dia hole. Can this small opening sized fitting (AN4022 I believe) be installed where the plug is now on each of my ECI cylinders and still conform to the type cerficate? I have looked thru a lot of engine photos on Champs that were on barnstormers and I haven't seen any with 4 position priming. Gordy in Mn
