The copper oil line to my oil pressure gauge sheared off at the compression fitting on the engine block. Oil dumped under rear tires and I enjoyed a nice high speed spin on a straight!
I'm guessing the line is not designed for the vibrations of racing (this was only the second race weekend on the line). Any one have this happen? I'm thinking that I should put a short run of flexible braided line off the block to handle the vibration.
Thoughts?
Electric gauge.

The only problem with an electric gauge is that I've not been able to find one with more than a 90 degree sweep. Is there such a gauge and, if so, who makes it and where can I get one?
Mechanical gauges usually have a 270 degree sweep and, to me, are much easier to read quickly.
To answer rlekun's question, Summet racing has a braided line kit for mechanical oil pressure gauges. It's a little spendy, but still less than buying the parts seperately and then you have braided hose all the way from the engine to the gauge.

Thanks, George. They're a lot cheaper than a mech gauge and a braided hose and fitting kit.

NO COPPER--EVER!
Very dangerous.The braided stainless is not really that expensive.
Autometer alsp has a few choices. Their 'full sweep electric guages' come in WT, FP, OP and OT...
Also, you mean 180 degrees, not 90, correct?

No, I did mean 90 degrees. Looking at the Autometer gauge pictures in the Summit Racing catalog, the numbers on the gauge face begin at about 10 o'clock and end at about 2 o'clock. One of the descriptions states that the electric gauges have a 90 degree sweep. OTOH, looking at the pictures of the gauges, the indicator needle does seem to have a little longer sweep than the numbers would lead you to believe, but that would be at the extreme ends of the scale and not of much use.
It doesn't look like Summit Racing has the 'full sweep electric gauges' that you refer to, but I'll Google for them and see what turns up. Where have you seen and/or bought them Andy?
BTW, I keep referring to Summit Racing because their catalog is full of great illustrations. I usually buy from Pegasus as they are a bit more in tune with our type of racing.

Both Summit and JEGS offer -3 and -4 braided flex brake hose lines. So do all the roundy-round retailers, like Coleman Machine and Lefthander.
Does your gauge know the difference between an "flex oil pressure line" and a "flex brake hose" ? No. Only your wallet knows.
A 60" -3 braided stainless hose with end fittings (already assembed) from Coleman is a roaring $23. If you want a 90 degree fitting on one end, it jumps to a horrifying $32. -3 to 1/8" NPT adapters are $3 each. They will do custom lengths, if you need something longer.
Electrical gauges suck. They always have, and they always will. Stick with mechanical gauges, where you can have sweeps of 270 deg.

Go to www.autometer.com
Click on the gauge pod unde rthe logo, click oin the 2003 Product catalogue, then under "Racing" there is section 70.
There you will find the Pro Comp full sweep stuff.

The plastic lines work fine, not sure if its nylon or polypropylene (probably polypro). You can usually pick one of those up as a kit w/o the gauge at any place that sells autopower guages. If it needs to get past a hot spot or rough spot you can use an 1/8" pipe nipple, most every oil pressure fitting I've ever seen is 1/8" pipe thread.

In part:
"All fuel and oil lines, including gauge....shall be of steel tube or metal braided hoses or bulkheaded."
We opted for the Autometer Mechanical with their braided hose kit. The hose is 6' and cost about $50. Meets the rule that spec's that you must use this type of material if you bring the line in to the gauge. If you go electric that is a different story and I would suggest a braided line from the block to a TEE on the firewall. Copper and Nylon are not suitable for racing applications.
