Pipet? You mean petcock? Anyway, you already seem to have an aftermarket petcock. It never occured to me to take pictures of a gas hose so perhaps just a work of explanation would help clear this up for you. I use extra long hose because I work on carbs for a living and do it with the tank on the bike. I can prop the tank up and avoid using an external fuel source when tuning the carbs (for VM type carbs anyway)... If I was running a bike where the carbs weren't coming off often, here is what I would do...
FIRST, come out of your petcock using a gas line long enough to make a smooth bend. If you use too short a line, you will kink it and gas won't get through. Run this hose to an inline filter... Use perhaps 6" of line to the filter. I avoid using lawnmower filters due to the poor flow rate. Others have used them and they seem to work sometimes. I have used car filters in the past... the kind with 1/4" inlets. Be sure to have the filter pointed in the right direction. there is generally an arrow for fuel flow direction. I have had real bad luck using Fram branded filters as they seem to clog up almost immediately. I have started buying filters in bulk. You can get motorcycle fuel filters inexpensively from
www.z1enterprises.com - Make sure you match the fuel inlet size with the size hose you are going to use. Most folks would do well with 5/16" ID hose... the black rubber stuff from any autoparts store works well. Use hose clamps.
Once you get the hose to the filter, come out with a short (about 4") piece of hose and go into a tee fitting. From the tee, run hose to your two fuel inlets.
The tee can also be purchased at any autoparts store... usually in the "HELP" section where they have the packages of fasteners and such. It is a "vacuum tee" made of plastic type materical and gas won't cause it to break down near as I can tell.
