    Great regulator at a decent price. The ONLY thing I did not like about it was the plastic vacuum reference barb, not really sure how durable it’ll be in the engine bay but time will tell. Also, it was glued it and wasn’t able to replace with a metal one. But other than that works as intended and looks great!

    Worked good on my Nissan hardbody KA24E pretty simple, does not include tools. You will need a 5/32″ Hex key and 1/2″ wrench to adjust it. Works as it should.
