Hey everyone,
I've been doing a lot of searching, both here and on the net, on how to tap the fuel supply line on the tC to install fuel pressure gauges. Best thread I saw was one about installing NOS (author was WeDriveScions).
He ended up just ishcanning the stock one and using fuel line he got from a race shop. Haven't been able to find out what he used for fuel line.

Does anyone know what diameter the hose needs to be? 3/8" maybe? You can get the adapters for the gauge and fuel line from Jegs, just need to know what size?

Thanks!

 

B-U-M-P and watching :D

 

Well, so far all I've found is that, according to TRD's supercharger install, and other maintenance sources, you need a special tool to even get the hose off without braking it. It's a little two-piece adapter standard in a Toyota Tech's Tool Box...I know, not much help to me either. I am amazed that between S/L,
Google, and Yahoo Searches, nobody seems to be doing anything to the fuel line. I ran into this problem when I wanted to just replace the stock rail with a nic one, and tap the rail itself for the fuel press. gauge. Most rails com with a 1/8' port. No joy. Perrin makes some nice ones for xB, but no love for tC's.

I don't like the idea of splicing into the stock line since it's hard nylon. The fuel clamps won't seal properly and who wants a leaky fuel line under the hood of their mechanical ****?! I'll keep looking, but any advice would be appreciated: I'm thinking still about just replacing the line itself and tapping it...
