I need a fuel pressure guage for our TBI application and I would rather not cut my fuel lines to fit one in there...any suggestions?

 

here are some things i thought of: besides running AN line.
1) get the straight piece with schrader valve from an air conditioning line and splice it into the steel line.
2) the better idea.... i saw this fuel fitting in jegs that i believe has the right fittings. it has a male/female end and a tapped hole that a schrader valve could go into. you would just unscrew one end of your rubber line and screw this piece in. then just put your schrader valve (i have only found air so far and don't know if they would be fuel resistant) in. then you should be able to use the same fuel pressure gauge as the tpi guys do.

There are adapters available that thread inline on the fuel line that have a schrader valve built in made just for fuel pressure readings. I know of a place here that sells them. They're costly though.

 

actually here in can.. they sell them at canadian tire.. expensive though.. I bought mine for $99 Canadian.. you remove the line from the tb and screw in this brass valve and then the fuel line screws into it.. leaves you with a nice fitting to screw the supplied fuel press gauge

 

That sounds perfect. But damn that is expensive.
