I know another fuel pressure question but please bare with me here; Im finally going to get a gauge but was wondering the difference between mechanical and electric gauges? Which is better? And I was going to get the fuel filter cap with pressure port on it from geno's. Is this a good setup or am I missing the correct spot to get the reading from?

 

well electric you will not have any fluid running in the cab, mechanical uses a isolator with fuel on one side and antifreeze on the other going in the cab to the mechanical gauge. Mech. is more accurate but electric is a piece of cake to install, some say they are accurate as mech. but i know my electric works good for me. It really boils down to what you want, they both are good setups!

alrighty. Thanks for the help. so it's ok to get the pressure reading from the top of the fuel filter?
