I need to run a fuel pressure test, and I am trying to find the optimal place to tie in my pressure gauge. I know a lot of Chevys have a removable cap just for that purpose, and I am able to find information for the location of those caps on later models, but I can't find anything for a 1980 K10 5.7L 8 Cylinder 350 engine. I could always tap into the line before the fuel filter, but if there is a designated location for the gauge to connect, I would rather use that and do it right. If anyone could tell me the location of the tie in point, or other ways of testing the pressure on that model, I would greatly appreciate the help. Thanks!

 

What carburetor are you running?

 

It's an Edelbrok 1406

 

You only need 6.5 PSI for your Edelbrock 1406.

 

You will need to check your fuel pressure at the carb inlet with a double hosed fuel pressure gauge. You run one hose to the carb and the other to the fuel hose from the fuel pump.

 

Thank you, I’ll give that a shot!
