Reuben's recent thread, coupled with my dissatisfaction with my Isspro O.P. gauge has me thinking about replacing it with a mechanical gauge and routing the nylon/copper/whatever feeder line to the gauge. I recall reading a post from Charlie saying not to route nylon tubing near the battery because the fumes would cause the nylon to deteriorate, and I've read the copper tubing has it's own set of issues with work hardening (heat expansion/contraction, right?), and everyone says don't run the nylon near the exhaust manifolds or anywhere extremely hot... what to do, what to do??? <img src="/forums/images/graemlins/confused.gif" alt="" /> <img src="/forums/images/graemlins/confused.gif" alt="" /> <img src="/forums/images/graemlins/confused.gif" alt="" />

So, let's hear from those of you who have done it... what sort of line did you use, how did you route it in the engine bay, where did you breach the firewall, and how did you route the tubing under the dash to the gauge?

Of course, some pictures would be very, very helpful <img src="/forums/images/graemlins/kewl.gif" alt="" />
