time to fuel up the 1H, can someone please describe to me or post a picture as to the location of the overall fuel mix screw on a 1HZ injector pump. its on a 93 model HZJ80 motor (in a 40 shorty :twisted: )

i know about all the exhaust temps and too much boost and fuel etc bla bla disclaimer disclaimer
i just wanna have a crack at it myself

cheers.

It is just above the injector lines. You wind it IN towards the engine to increase fuel, start off in small increments as every pump is different. You really do need an EGT gauge to monitor and give you an idea of what is happening.

I highlighted my original position with a white paint marker and a blade before making any adjustments.
Here's a pic;
