main internal threads were rough on the unit i received, it kept dripping even with thick sealant and teflon tape. possibly a dull or chipped threads in the tap that was used, maybe the next one will be perfect but it does the job and price is good, sure can't complain about how fast it arrived.

My fuel pressure with a high volume mechanical fuel pump and this regulator gave a huge variation in fuel pressure on a gauge. I swapped out the fuel pump for a low volume stock pump and I could read the gauge. The lock nut split the o-ring seal and I had to replace. It doesn't work as it should for my application. May work better on a low volume, low pressure, small motor.
