Oil pressure gauge line leaked --> need new carpet

Not sure why, cuz the connections are very straight forward, but the AutoMeter mechanical oil pressure gauge in the '73 leaked at the fitting during the initial start-up and soaked the d-a-mn carpet w/ 10w40. Nothing looked wrong, but...

Anyone trust electric oil pressure gauges instead of mechanical? I always wanted mechanical for "real time" response & readings, but am now wondering if I should swap it out.

$.02 either way appreciated. Thx

initial start-up- Was the gauge new, was it a new install? If not how old was the line? Plastic/copper line? Id not let one bad time make me stray from a mech. gauge as much as it stinks it happened.

Ive had a few of the plastic line units develop a drip after many years so I just bought the line/fitting kit and all was good.

What kind of line are you using? I use stainless braided line, never had a leak. Bad fitting?

New AutoMeter gauge with new AutoMeter braided line kit

I’d make a new line & fittings. That supplied line is probably from chino

Dawn Platinum and hot water washes it right out.

There's a brand new ACC carpet sitting in my basement waiting for me to pull the interior out... but I haven't been motivated to mess with it

The braided line and AN fittings should be the best. But something didn't go right...
Hard to say if it wasn't tight, debris in the AN flare, or fitting didn't seal to the hose. I would just cut off an inch and remake that end.

If you a 1/4 inch size line instead of the tiny standard size tiny line (CRS on that proper line size #: blush:) the oil pressure gauge will act like a tach, immediate response

i believe most oil pressure lines that come with [almost] any guage are 1/8".
aren't most a/n conversion hoses -3 ?

I'm thinking they are 1/16 I.D., not 1/8 I.D.
The 1/4 inch I.D. copper line I used work like a charm, it was enlightening how rapid it would change readings when driving the car or revving the motor up out of gear
I was told by a NHRA tech guy later to remove it and put the smaller ling back in that bracket car
Looking back I should have used a stainless covered #4 AN line and fittings

yes, 1/16 inside diameter, 1/8" outside diameter Cab.
i was referring to the OD. sorry for the confusion.
i also like the larger OD tubing/hose for fast response time.

Maybe bad fitting on the gauge end. Should be a clean -3 or -4 an male fitting there. Could be is buggered up a tad on the angle on the flare?

Yep, same happened to me, the plastic line kinked and split a little allowing oil to drip onto the carpet, I went to an electric autometer, then to a Dakota dash. No issues, both are very responsive. IIRC the race scrutineers don't like oil lines in the drivers compartment anyway.

Just checked out AutoMeter's electrical options: a standard version about the same $ as the mechanical I have now, and a "hi zoot" version that's supposed to be very sensitive to pressure changes.... but also costs 3-4 times what the simpler gauges do

Will give the current fittings and hose a good close look and see if anything obvious is jacked up, then go from there

Well sheeet, there's your problem !!!

Used one of these for 10 years on my oil pressure gauge, was left over from a job, works great. Its 45 deg flare.
