<html><head><meta http-equiv="content-type" content="text/html; charset=utf-8"></head><body dir="auto">An isolator is a device that sends the pressure signal to the gage using a different fluid (diethyl ether or more commonly propylene glycol). If the gauge fails, the fluid that gets sprayed into the passenger compartment is minimal and non flammable. The isolator normally sits in the engine bay. That way the number of fittings in the fuel line within the passenger compartment is minimal. Should be zero imho.<br><br><img src="cid:25DB3930-B5A1-4929-A647-67F809A15E12" alt="image1.jpeg" id="25DB3930-B5A1-4929-A647-67F809A15E12"><br>This is a low pressure isolator (0-15 psi). Gauge line goes out the back side through the firewall. For fuel injection systems there are high pressure isolators available. An alternative is to use an electric gauge with sender under the hood.<div>Phil Gott <br><div id="AppleMailSignature" dir="ltr">Sent from my iPhone</div><div dir="ltr"><br>On Mar 1, 2019, at 7:05 AM, Brian Schirano <<a href="mailto:bschirano@yahoo.com">bschirano@yahoo.com</a>> wrote:<br><br></div><blockquote type="cite"><div dir="ltr"><div class="ydp38dd519fyahoo-style-wrap" style=""><div style=""><div style="font-family: times new roman, new york, times, serif; font-size: 16px;">Hi Guys</div><div style="font-family: times new roman, new york, times, serif; font-size: 16px;"><br></div><div style="">very interesting talk on the EGT probes.

<div>I've always heard that if you have a balance tube between front
and rear carb that you want to run in 1 and 4 so you can better
isolate which carb you want to adjust.</div>
<div>I have mine in 1 and 4 but run webers so no balance tube. I see
up to 1450 F at the end of long straights. Much more than that
and I start to transfer aluminum from the piston to the cylinder
walls. I think there's some variation in temp readings between
different probes and gauges, I don't know what the accuracy really
is.</div>
<div>It's a great troubleshooting tool when the car starts to run like
crap. Another helpful tools is a fuel pressure gauge (with
isolator so you don't pipe gas into the passenger compartment).
Pressure too high overruns the floats. To low and you've got
something funny with the feed like a regulator / pump going bad or
you forgot to put gas in the car.<br clear="none">
