The fuel regulator works as stated. Once I decided on a mounting location, it was assembled and easily installed. Also very easy to adjust.

Ace's products are a must buy. Yes they are a little bit costly, but well worth the money that we have spent on their products. Highly recommend!!!!!!

Works good but the pressure gage threads I can only get two to three threads to screw in. it's not Cross threaded because I can take it off and still thread the plug in with no problem and even another gage. But I do like the one that came with it but it will not thread all the way in. Please send another.
