When using a liquid filled gauge it is not a good idea to put them in a hot environment. The excessive heat will eventually cause the liquid (glycerin) in the gauge to overpressurize and blow out the seals letting all of the liquid leak out, ruining the gauge.

Good point....so..a dry gauge that bounces around like a spastic butterfly might be a better idea?...or is a s#!ty non mechanical dash mounted gauge?...

Or you can get a new cowl with a gauge pod and use a liquid filled one.

Ever heard of a gauge snubber/damper or isolator?

Actually...no I haven't as far as use for reducing vibration..but I may look into it...really a permanent f/p gauge isn't "needed" in my application,just like to know what's goin on as much as I can...155K on the block!...and still running strong!!..
Thanks for the answers..i will be posting more questions soon..i.e power loss under full throttle in first gear ONLY!..???...

The snubber/damper won't reduce vibration as such, but they will help keep the gauge needle from bouncing around too much.

The isolator will allow you to mount the fuel pressure gauge inside your car for better monitoring of your fuel pressure.

Are you experiencing a power loss for sure....or are you just hitting the rev limiter?

Deffinate loss....if I could explain it better its almost like a cracked distributor in the rain(if that makes any sence)...
New msd wires,cap,rotor,new plugs,and plug wire insulators...
The problem was worse before it happened at half throttle..then I cleaned the "salt n pepper" shakers
And it seemed to be gone,but I also just replaced the flywheel and clutch so I couldn't really lay into the throttle till now(needed to let the clutch and f/w break in properly)
And as I said before it only happens in first gear at full throttle,and if I let off the throttle fer only a split sec it goes away..??...prob why it goes away when I shift to 2nd...

You say you cleaned the ten pin connectors correct?
Did you happen to spread the pins out a bit to ensure good connection while you were at it?
Have you checked your TPS voltage range?
Fuel pressure correct, filter clean, etc.?
Timing set correctly?

Throttle position I have not checked I will do that as well...fuel pressure im in the process of checking..filter is new and timing's good...thanks for the help!...
