can anybody recommend one that i can get locally

 

You can probably use the loan a tool at any Advance Auto/Autozone etc. I bought a Hypertech one from Summit years ago that works great.

 

I looked under the hood today and it looks like there is no actual port for a pressure guage.

When i looked at the service manual later, it looks as if you have to relief the pressure and connect into the fuel rali... It seems its a little more complex then usually.
