this weekend the oil pressure pipe that connects to the pressure gauge fractured in my '88 cvh engined morgan - spewing oil everywhere. I would like to change the gauge to an electric one.

Is this a pretty straightforward task for the novice amateur mechanic or should I be heading to an auto electrician

I guess there is the argument regards whether mechanical is better than electrical so any thoughts on this too

Easy enough job, but I'd stick with a mechanical gauge for oil pressure. With an electrical gauge, there's always a question mark over whether you can really trust the reading on the gauge and you definitely don't want that when it comes to oil pressure.

You can get suitable bsp fittings to replace the standard plastic pipe with a -3 Aeroquip line which will be totally reliable. Someone like Merlin Motorsport will make the pipe up for you if you give them the dimensions required.

Electrical gauge is simple to fit, but I'd rather rely on a mechanical gauge given the choice, as suggested I'd get a replacement hose/pipe made up and replace it.

thanks chaps, I think, having reflected on it that a new hose will be the way to go at this point, if it lasts for another 23 years all is well

I fitted an electric sender, still have the pressure switch fitted so will get a red light if there are problems.
Electric sender is 1 wire from sender to gauge, gauge has 3 wires and separate illumination
1 wire from sender
1 wire to earth
1 wire from ignition switched +v
Simples

A feed earth for the engine block and no ptfe on the sender thread
