bought an oil pressure gauge...

[Marz]

I just bought an Autometer 2 1/16" oil pressure gauge. It comes with a nylon tube. I am a bit ... aprehencive... about using a nylon tube in a hot engin bay. Have any of you used this nylon tube? Have you had any problems? think I should use a copper tube instead?

Also, I was thinking of using the Autometer gauge along with the factory gauge. This would mean putting a t fitting on that existing extension. Do you all even think it's worth doing this?

Thanks

u should be ok with the nylon tube....just be sure to keep it away from the exhaust manifolds and use a grommet thru the firewall, and u'll be ok

cliff notes version: SS braided is the way to go, don't use copper or the nylon. I have a mechanical oil pressure gauge I need to install too, haven't had time yet though.

been using mine now for about a year no problems....

I HAVE used the nylon.. and its ok because it doesnt kink like the copper. Braided is the way to go. Saying that.. I swear by copper, havent had a problem in 20+ years

I was actually thinking of dumping those fittigns Autometer gives you for Swagelok fittings. I use Swagelok fittings for pluming some of my equipment here at work and haven't had a problem with them. I can also scrounge around for 6' of 1/8" copper tubing (I believe thats the size used). I feel the Ferrul on the Swagelok fittings are a much better design than the ones suppliey by Autometer.

Thank you

Nylon is fine never hjad a problrm, varrol shelby used them in his shelby mustangs and british cars like the sunbeam tiger used nylon so i dont think there will be any huge problems if hooked up correctly.

I have used copper with a loop in it for vibration with no leaks have had a nylon melt on me once so copper would be my choice again

Thanks!

I'm actually going to do the Cu line up to the frame rail (just before the PS pump) and do a 90* bend then hook a custom made SS braded line going from the Cu line to the sender extension.

A couple of drag race friends of mine had recomended I not do the Cu or the nylon lines....The heat and constant vibration will cause the Cu line to Anneal, crack and eventually break. But they did not have a problem with the Cu line being used with the SS braded line as a flex line between the engine and the Cu line.

Also, I like the idea about the rubber vacuum hose being used as a heat shield.

Thank you all.

I've had both the nylon and the copper lines. If you take the car to a track, the nylon is no-go and some tech guys will flunk the car.

If you anneal copper, it's less likely to break because it would be softer. Braided stainless is best but most expensive. Aluminum tubing is also an option.

Braided is the way to go, yet I'm running the stock nylon on my car. Never had a problem. Just make sure the bends are gentle. I ran mine through an existing hole in the firewall, then along the top of the driver's side valve cover (hidden under my upper EFI intake), then down the block behind the A/C bracket. You can't see it unless you're looking for it.
