Loose Bolt:






How to adjust this bolt:


Any hose on this tap:






Broken and glued:


Intake throttle removed, nozzle out of hole and a tube over make it easy to see if you have enough pressure and if nozzle deliver:

OK you don't want to tell us about your fuel pressures. Do you not have a gage?
Describe what we're looking at on the you tube.

Yes of course, but some friends stop by to see if they could help so we went to the workshop and tried all their ideas allso (no luck).

My pressure is 55psi with the brand new pump, not overwhelming but rises when i turn key to start starter, after 30min i still have very close to 55psi and not under 50psi, and i dont have any leaks.

The only place you can smell unburnt fuel is out of the exhaust.
Still not finished welding the exhaust so it is not all the way to the back.

On youtube i have removed the intake throttle and fished one of the injectors out of hole

The tube you see is placed on the injector to see if there was enough pressure to push the spring ball and deliver some fuel which went well.

Pretty easy to do and no guessing about if you need 55 or 60psi pressure

Have you checked the fuel volume? How much comes out in 30sec after the fuel filter?
