				Looking for some insights on installing a vertical sump IO-360 on a 7A. I ordered a TMX-IO-360 and have my FWF kit. Vans had me get the O-360 FWF with several adjustments. I installed my boost pump and filter per the Vans drawing but stopped short of plumbing the feed line from the pump to the firewall because I couldn't determine where to penetrate. The Vans drawing are for horizontal sump IOs. 
 
 My first question was whether the gascolator was used with the IO installation. A search of old threads indicates it is optional but recommended. So I guess I'll be adding that. 
 
 Does the Vans gascolator work with the IO engines?
 
 The next question is where do I penetrate the FW? The IO FWF shows the penetration more to the center than does the O-360 drawing (lower right corner at the gascolator). I'm sure many builders have crossed this bridge already so I would appreciate some hints. 
 
 I'm thinking the gascolator and FW penetration should be per the O-360 drawing, is that right?
 
 Any other penetration peculiarities I should expect?
