I would reread the email instructions from Terry as noted.
Ordered from Sampson. Terry sent me an email that I need to read more carefully, but he said there's another way to install it as a T into the supply. I think it'll be better to look at everything and read the email with all the stuff here. Can't wait!
Taping into the supply line is very HI pressure, not a good idea. The method I used( BMW LT ) when taping fuel supply feed from a aux cell was to T into the low pressure return side. This also required a low pressure fuel pump. The FJR does not have low pressure return lines.Terry could be assuming the FJR has a low pressure return.
Get ready to drill the hole ,for the bulkhead fitting. Hope this helps..
