There seems to be a lot of information on how to mount these, no two are alike, and each method is a unique combination of benefit vs. compromise. Here's my take.
It starts with a new bracket made from a 12" x 12" sheet of 4130 purchased from McMaster. A hacksaw, files, and the dirt-cheap break from Harbor Freight was all it took to make this. The tapered shape and bends were made to exactly match the existing Lycoming bracket which mounts the fuel divider, and the bracket uses the same 1/4-20 bolt as its primary point of attachment. Opposite this bolt there are two tabs which, with the use of Adel clamps, provide additional support to the bracket by attaching to the push rod tubes. This is admittedly the compromise in this design, but great pains (and three different attempts) were taken to build this so there isn?t any load in tension or compression on the tubes.
Two new fuel lines were necessary, made by the very capable hands of Tom Swearengen of TS Flightlines; one a stainless steel hard line running from a bulkhead fitting at the rear baffle to the transducer input, and one flexible/firesleeved line with 45? fittings running from the transducer output to the divider. On a side note, it?s been said many times and I?ll add to the chorus, Tom was a great guy to work with, his knowledge is unsurpassed, and he demonstrated a great amount of patience in dealing with a rooky like me.
The next two photos show the clearances of the new plumbing with the existing injector line plumbing. I?ll finish the install with an Adel clamp to secure the flex line to the divider bracket.
