Fuel/Water Separator turning black

Ok,
Ended up being fuel pump was overheating fuel up to 150 degrees.
It was causing asphaltine.

NOW...

I've done had to replace 6 injectors!!
As soon as they're put in they are being damaged within 200 miles and most within first 40 miles.

Fuel rail was changed and I was told there was nothing dirty between fuel pump and rail..

I just had engine rebuilt in October and then after the fuel pump started this nightmare..I'm pretty much out of funds and resources now.Its all about but wiped me out.

The shop is working with me on payment but I'm about to my end.

Any knowledge,opinions,and responses are fully appreciated..

 

Fuel pump was coming apart so it's taking out injectors now.
All gauges are normal and has never been a engine warning light flash or come on.
Something's just killing injectors now.
Engine ran the best I had ever seen it before this last injector but as soon as it kills injector naturally back running rough and fuel mileage plummeting.
