where can i put a mechanical gauge in temporarily to check fuel pressure?

 

anywhere in the fuel line closer to the engine the better. just go to a hardware store, get a brass T and get threaded barbed ends on 2 sides and get bushings to reduce down for a mechanical line on the other side.

i got all my stuff at napa for like 13 bucks

 

x2 thats what i did to hook one up or a temp. period till i can get my own

 

Fuel filter housing!

 

thanks guys need to check fuel pressure cuz truck not running right

 

Install a permanent guage. Drill and tap the banjo bolt on the IP lnlet (1/8" npt)

 

How much psi do p-pumps need?

 

10 to 38 ish. Depends on load. More load = more psi.

 

mor pressure more power
