Just finished my winter, I know, fuel line R&R front to back and put a few gallons in the tank.
The fuel pump wouldn't fire which will be a problem for another day. 12V direct to the pump and it runs, however no fuel to fuel rail. I'm thinking I swapped feed and return lines when I swapped in the Tangerine same sized SS lines.
Because the FP is located under the tank, I can barely get to the power leads from under the car but not enough room to swap the hoses over. I'm thinking may be easier to move a few bits and test swap hoses in the engine bay.

You may have kinked your feed hose under the tank, you have enough room to feel along the hose looking for kinks.

You did take the dust plugs off the lines before you put on the hose right?
Had a customer who did that on a new MC.

IIRC there were no plugs in the lines, I'll recheck for kinks but I cracked the lines where they exit the body tunnel and had fuel in each but still nothing running to the rail, or I should say the cross over line from left rail to right rail that I checked. Probably should not have left the pump with no gas in it for 8 months...
