Yes, it is possible. Though When I blow through the front hoseI believe the fuel flow is pump to rail to regulator and then back to the tank. A "clogged" regulator should cause overpressure at the rail. Is it possible that the two fuel hoses are reversed at the tank?
Is the pump outputting pressure through the filter? If not, double-check the wiring connections to the pump to verify they are not reversed.
If you are getting fuel delivered to the rail connection but none at the rail itself then yes, it’s possible the regulator or rail has collected a load of debris or dissolved rubber spooge and is blocked. Brick-k bikes that are allowed to sit long-term with fuel in the tank tend to have the rubber mount bits dissolve into a viscous spooge that is destructive to pumps, filters, regulators, and injectors. But usually the pump and filter fail before the spooge can reach the regulator and rail.

Yes getting fuel to the rail connection, but it doesn’t,t seem to be returning to tank out of regulator. Will get into it more tm I think the rail or line going to regulator or regulator is blocked.
Thanks
You are correct. I was thinking the fuel came in at the rear of rail, but It’s going out to the regulator from the rear. Then from regulator to tank return. I think the line to or from regulator is blocked. Will investigate tomorrow, thanks.I believe the fuel flow is pump to rail to regulator and then back to the tank.

Fuel is flowing into and out of the rail and back to tank. No , getting spark but spark plug dry. Going to pull rail and see if injectors are spraying. I don’t think they are.You are correct.

Going to pull rail and see if injectors are spraying. I don’t think they are.
The injectors didn’t want to come out. They are really dirty. In the holes they go into are full of crud. I’m trying to figure the best way to clean them out without getting stuff into the opening. Maybe some kind of rubber plug and then flushing it. I’ve heard you can send the injectors off to get them cleaned or some people do it themselves. or buy upgraded ones.Fuel is flowing into and out of the rail and back to tank.
