As I start looking at laying out my next project, I am trying to decide which way to go with a couple of after market gauge. This is for my 68 Road Runner. I like the idea of electrical oil pressure gauge as its a bit easier to run a couple of wires than a tube. Does anyone have experience using electric? Would a decent gauge like an Autometer have fast enough response?
Just curious what others may be doing.

For my new GTX build I went with electric for everything but the oil pressure. Just could not pull the trigger on electrical for such an important function.
Quality electric gauges are expensive. I paid a lot for the gauges.

To answer your Q. In all my years I have only seen one that had a slight drip. Tube fracture or fitting failure ?

There is no problem using a QUALITY electric gage. As mentioned above, virtually all auto manufacturers use electric ones.
One thing that I always do with my oil pressure gage is to "T" the block port and put both the gage pressure sender and an idiot light sender in it. The idiot light sender goes to a small red blinking LED that can be put in a lot of different places in front of the driver.
With a large selection of trigger points available on the light senders, you can set on-point of the light where ever you want. I usually set mine somewhere around 10lbs.
The warning light pieces can be done for $15 or so at any auto supply.
Master, again and still

I've used the braided stainless line in my other car. It was a bit more difficult to route around stuff. Id line to get the gauge up under the dash pad over where the clock would be. So not a lot of room to make bends with thicker braided line. I could probably fish a pre-bent 1/8" stainless hard line for a short distance, then connect flexible stainless under dash and through firewall to engine. But a couple of wires would be much easier. And I do like the ability to have a low or hi limit alarm. Costs aside, if it has the functionality I want, Ill buy it.
Thanks all.

I had an electric oil pressure gauge in mine and when a couple of the other electric gauges went bad (Cyberdyne) I swapped it out for a mechanical one even though routing the hard line was a pita... One thing to watch is you have to ground the gauges to the engine and not the dash...I turned the radio up and the oil pressure dropped and water temperature spiked...grounding to the engine corrected that... 1st pic is the Cyberdyne gauges... 2nd is the new Stewart Warner Green Line...
...FAFO...

To answer your Q. In all my years I have only seen one that had a slight drip. Tube fracture or fitting failure ? I ain't for sure (many years ago), it was a slight drip right behind the brass fitting at the gauge. X2 what Dave said, T into the port & add (or keep) an idiot light & use a sender that turns on higher than the OE ones, 15 maybe 20 psi.

I like mechanical. I used copper tubing when I did my truck years ago with no problems. I personally like Autometer gages. In my 2001 Cummins dually I used air brake tubing with push lock connectors. I also used needle valves under the hood so if there are any leaks I can close the valve at the source.

If I was driving a choo choo with a boiler then a mechanical gauge might make sense.
Otherwise it doesn't. Modern electrical gauges are lights ahead of mechanical ones.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

That's exactly what hit me earlier when this thread got me thinking which was to add a valve at the eng port if there ever was an issue. I ain't sure what a needle valve is but I will Google it & add one on my next build if I use a mech gauge.

yay, you found a fitting, how fitting. Pretty much anything not stone aged technology, including Lycoming there, uses electrical gauges for a reason. They are more precise, more accurate, more flexible and more responsive.

Short sweep Autometer electric gauges. Been running them for years without issue. I did have a cheap mechanical piss all over my shoes once. Had to drive home one-handed while I was crimping the line with a pair of pliers.
