Hi Paul and everyone, I am looking for a vendor for bulkhead
connectors. I need to supply electrical power to the intank fuel pump
and need to have a sealed connector. I'm coming up empty locally and
even on the Internet. Someone has to sell these they are in every
automobile around. Any help here is greatly appreciated. T.W.
Digi Key is who you are looking for.
They carry just about everything and service is good.
What you want are Amphenol AN type aluminum shell bayonet with
gold plated pins, Page 212 Sept Dec 2004 catalog.
A size 12 pin will take 23 amps. They have them up to size
8 pins. Or .125 inch diameter wire. The smaller the number
the bigger the wire. You might have to epoxy the back
side to seal them.

BTW I was thinking a good way of backing up your electronics
is to use connectors reachable by the pilot
and have spare electronic parts in the airplane that
can be plugged in case of a primary electronic part failure.
Here is a good example. These MicroSquirt EFI computers
are just a bit larger than a Quarter coin. You could carry
two or three of them in the airplane. One fails so
unplug it and plug a new one in.

I would consider just cannibalizing one from a standard automobile
in-tank pump module. I've been thinking about using the whole
module. Not necessarily this one, but this one is typical. (from a
GMC Safari 4.3L, 1998).

Speaking of in the tank pumps Klaus Savier LSE showed
me his new aircraft EFI system. Dual units just like Tracy uses.
He controls the fuel pump speed so no fuel return line is necessary.

Paul,
Could you explain the picture in greater detail? Ie: where is the pump
and why three outlets? I suspect this is not Klaus's work.
Doug F.
You got me. One is probably the feed line another the return
line and the third a vent line. The pump is down at the bottom
of the picture not fully shown. Nothing directly to do with
what Klaus is doing other than eliminating the return line.
