4hg1-t pump info

Postby Jaynpr300 » Sat Apr 02, 2022 8:38 pm

Hi all
Hoping to get some help to identify where the fuel screw is on this zexel pump fitted to the 4hg1-t in my npr300.
I found this picture on eBay , exactly the same as the pump on my truck but less clutter for anyone kind enough to mark up the picture.
Thanks for any help

Under the tin tamper cap in the middle of the picture. It acts as a stop, so screwing out is more fuel.
