All fixed and running.
Confirms my previous suspicions the pump was going bad, car was quick before but is a totally different beast now at all rpm ranges.
Old pump out of holder
New pump in
Mounted
Crimp hose
Connect it back up
New strainer
Mounted back in, youll need to figure out how to seat the gasket
After that there is a metal circle ring that screws on top of that. Hand tighten and tap it with a screwdriver and hammer a few times to tighten down.
Connect up hose/clamp, electric connector, then 4 10mm nuts for top cover plate.
Reinstall seat and 16mm bolt for middle seatbelt.
Done
