Also should I put a liquid filled fuel pressure gauges that goes in line.
I have been told that both these items are well worth putting on.
Do all of you run them ?

SCOOP,
Are you having fuel delivery problems?
If not, why do you think you need a pressure regulator?

It's my understanding that a regulator is only needed if you have a fuel pump that may be delivering more than 8PSI of fuel pressure to the carb, which would overpower your needle valve producing a flooding condition. However, by using a pressure regulator you can dial down the pressure being delivered to your carb. I'd guess that your mechanical pump isn't delivering that level of pressure (I'd take the model # of your pump and then check it against the manufacturer's specs to determine what range of pressure your pump is designed to deliver; such as 5-7psi).

Does the gauge need to be liquid-filled? Only where you've got LOTS of vehicle vibration which could cause the gauge needle to swing wildly would a liquid-filled unit be necessary. I'd guess that since you're not running solid engine mounts on a race-only car, you don't have that level of vehicle vibration. But they do look cool,,,,but you also run the chance of them developing a fuild-filled leak.....which can make a mess.

If you're like me and simply want to know what your fuel pressure is, then I'd suggest you do what I did. I installed a good-quality (i.e., Autolite) mechanical fuel pressure gauge at the cowl, with a piece of rubber between the gauge mount & the cowl to serve as a gasket & reduce the chance of marring the cowl surface. I tapped the pressure line into the end of the carb fuel delivery line and then using a cup mount, it is a relatively weather tight affair. I didn't want to bring the gauge inside to the dash because that would of meant that I also bring a pressurized gasoline line into the drivers compartment, because of the potential fire hazard of having a pressurized gasoline line in the cockpit area and it would be against NHRA rules. Yeah, I could of used an "Isolator" that mounts between the signal source and the gauge and keeps the gasoline out of the drivers' space, but I didn't want to spend that much more $$ to monitor the delivery pressure.

I've seen where some folks mount a mechanical fuel pressure gauge inside the engine compartment, which is alot easier to accomplish. However, I don't see much benefit to doing that since it wouldn't allow me to monitor the delivery pressure when it's being maxed out as my car is going thru the eyes.......
