How do adjust FP with a Kirban?

I have a Kirban, but don't have instructions, so which way do i turn the bolt with an allen key to lower the pressure? I don't have a gauge but I really need to tune it down.....

I have the instructions that came with mine, but it doesn't say which way does what. I haven't adjusted mine yet as my car still isn't running. You really should get a small fuel pressure gauge. I got an Autometer 1 1/2" gauge for like $30 from Summit (Summit also offers their own gauge for $20), and the necessary male to female fuel rail connector for like $8. Here's a pic of the gauge on my car and what my car looks like right now:

I might get a gauge, but doesn't the needle bounce around a lot making it hard to dial in?

I use the gauge at work, but do't want to risk getting yelled at for using it. So if I can't get a gauge, I'll ask to use the one at work....

Do you need any special fittings to mount the gauge? If so what size? I've heard of people using pressure gauges from home depot, I might try that today....

You need a special guage that connects to the Schrader valve and no mine doesn't jump around it is pretty steady. Usually, tightening or CW gives more pressure when adjusting the FPR.

Good Luck, Don

Do you have to turn it a lot to change the pressure? Or are the adjustments very minute?

My BBK is about 1/8 turn per pound, but they are all different.
