Just a quick update, Tried the electric fuel pump and fuel regulator, gave up. Leaked fuel everywhere, will try again when warmer. Fixed a few electrical issues, rear fog light, bulb not earthing properly. Quick clean up of the electric points sorted that. Heater blower now has two speeds, The plastic prong inside the switch had worn down. Made a few mods so it would stick out further, now works fine. One of the bulbs on the dash wasn't working, so dash out and a quick fiddle sorted that. Can see all the dash now. Just need to fix the broken speedo cable when it arrives. Been buying parts from Poland through my cousin over there to replace all the rear end suspension, brakes, etc. Hoping to have all new running gear for when my son passes his test. Done a few more miles now, car running fine, definitely benefits from regular running. Changed the front indicators to clear ones.
