Making a petcock adapater is currently on hold. I sent a couple designs which may work to a cnc shops for quotes, but I didnt really like any of them. What I would like to find it a pre-made hose barb coupler with a flange mount, then place an intank fuel filter on the end of one barb, and a remote petcock on the other end. EIther that of risk screwing up the paint and tank lining by welding on a 22mm bung...
Supplies for the wire harness are now on order. I was too cheap to buy assorted colors of assorted wire gauges, most places only sell 100' spools which can get pricey. SOme people sell assortments on ebay, but I tried to limit my order to a couple of suppliers.
SO, from waytek:
20AWG Cross Linked XLPE Wire (Yes, I said 20AWG)
14AWG Cross Linked XLPE Wire
35A SPDT Micro ISO Relays
SPDT Micro ISO relay sockets (and terminals)
Assorted polyolefin heat shrink tube
1/4" Expandable Sleeving (In hindsight something with a higher temperature resistance than 250F should have been used)
Misc bullet connectors for low profile connections in headlamp
From Allied:
TE Mini MLC 7 Pin connectors ($2/ea)
TE Ampseal 16, 3 and 6 pin connectors ($2/ea)
The miniMLC connectors are fairly small, considering the pin density, but low power so I am using that for connecting control switches to relays.
The Ampseal 16 connectors come in both 20 AWG and 14 AWG versions with contacts rated nearly 20A. This is fine for most stuff, but if you want something higher power you may consider the molex mx150L series, they are cheap, sealed, and can handle 20-40A. The problem with the mx150l connectors is that they are really long. THe ampseal conenctors are fairly compact, and you could double up on the contacts to get a higher current rating.
