Today I got some parts, and started to work on the heater hose situation. 2x 5/8-3/4 hose adapters, 90* 5/8, 1ft of 3/4, few hose clamps and an evening in the garage. Afterwards I filled up the radiator and waited, nope no leaks, I kept adding more coolant as the block burped itself for few minutes, than filled up the reservoir and called it a day. The fuel line I got was wrong - 3/8 vs 3/16!!! DOH!! I hate SAE crap. MM is easssy!!! Oh well, got to go back tommorow and get the right one.
I also talked to Gary and he can help me with the clutch line situation, so that I don't have to order a new one from Nissan.
