I need to know where 3 and 4 go to on the card, i believe i either have issues with timing, or the fuel lines being swapped.I'm pretty sure i got the fuel pump installed properly with the pin installed properly and all that.

An easy test for your fuel line hookups to pump is, disconnect top line coming out of pump at carb & get someone to crank the motor. If you are getting fuel, you've got it right.
As far as identifying which line is which: there's 3 lines connected to the tank. Supply, return and vapor.
- vapor line runs down firewall from charcol box, winds behind brake master cylinder (I have same year MM as you).
- Supply line comes into engine bay from frame a bit more forward then return line. The metal line (eg: where it connects to flexible line, just above motor mount if I recall) is slightly bigger then return line. The supply line flexible section to fuel pump has a hard, plastic section over it shaped somewhat in shape of a long "S" (maybe 18 inches long). This hard section is longer and has more twists then the one on return line.
- Again, return line comes into engine bay a bit further back towards firewall then supply line. If you can get a light down there (or get underneath and observe), you can visually see the smaller hard line (return).
I just finished replacing my Mikuni w/a Webber and do not recall fuel hookup locations for the Mikuni... I pulled Mikuni off and threw it away.
As far as timing goes: did you pull distributor out completely?
If so, I had to do something do get it back in properly I haven't seen mentioned here or in YouTube Videos on how to do this: eg. I had to remove thermostat casing from intake manifold. I installed my dist. several time before doing this, and that casing always forced me to turn dist. housing a bit clockwise further then seemed correct.... motor would puff and hickup like it wanted to start but never got past that. Read a bunch of stuff where others tried "guessing" tricks. Decided to pull that thermostat flange, distributor went in much more smoothly and motor fired right up afterwards.
