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? Jekyll Read this topic online here: http://forums.matronics.com/viewtopic.php?p=27419#27419
