Need advice on how to wire fuel pump for webers, it is currently wired to the coil.

Wiring the fuel pump is a half assed way to do it. It is also very bad for the engine. It lowers the available voltage to the coil, and weakens the spark.

I would suggest that you wire it to the fuse block, to the fused side of fuse #8 (IIRC). It will switch on when the key is on, and won't pull load from the coil.

Here's what you're looking for:
