any body with ideas or pics on installation of Vans gascolator at bottom of firewall? motor mount seems to be in the way.
 
My RV-4 does not have a gascolator (I didn't build it). It was built with a couple of in-line fuel filters (Flow-Ezy brand) which have replaceable elements. 10 years old and 500+ hours with no problems. The low point is the tank drains.

Type in "RV-4 gascolator" on the search field in this forum..you'll find some pictures including one of mine that may help.
