I used a 48" probe.

 

I did not use the fuel pick up in the manual.  First I fitted the slosh doors recommended by Lancair.  They supplied a kit of the hardware.  Secondly from Lancair I received a different fuel pick up which is inserted into the end of the tank as follows

 

Lancair supplied two pieces of brass 3/16" x 11/2" square.  In the middle of these pieces is a 3/8"" pipe thread.  A finger type screen filter fits into this pipe thread.  The brass piece is potted into the end of each tank at the lowest point.  To access this filter and make the pipe connection, once the wing is on the aircraft, you have to cut a hole in the outboard web of the stub wing before finally fitting the wing.  This hole has to be big enough to allow the connection to be tightened with a wrench and this will also allow you to get a socket in there to remove the filter screen should you so wish, once you have removed the pipe.

 

If you look on page 17 Chapter 11 of the Lancair Manual you will see the same set up but applied to the header tank, using an Al fitting instead of the brass on I used.

 

I have one spare  filter and brass piece that I could lend you to copy.
