you need a "T" fitting if you want your stock gauge to continue functioning along with the new gauge.
Noob here. Did some searching and came across this thread (good info.)
I have a '99 3.0. This truck has been bullet proof (well, not including some rear brake problems.) Anyway, I'm suffering the same oil gauge problem with mine. First off, I just want to confirm some things. I know nothing is "for sure," but it seems like most trucks with this problem are likely to be "mechanically" fine (appears to just be a crappy gauge.) If so, that is good.
The common fix appears to be aftermarket gauge(s.)
1. Is there a "kit" out there that will come with all parts needed (gauge, piping, etc.?)
2. When installing a mechanical gauge, will that mean the oil, in essence, will travel "through" the gauge to register its pressure? Meaning, there will be an oil "path" running through my firewall into the cab? If so, improper installaton or accidental damage to the gauge could result in oil getting inside the cab, right?
3. Wicked Sludge - that's a great picture you have, but I'm having trouble visualizing exactly where that is under the hood. Any further hints?
Thanks!
