Fuel Pressure gauge I'm getting rid of my useless air to fuel ratio gauge and picking up a fuel pressure gauge but have a couple questions.
I wasn't looking to spend a lot of money so I may have to go with a mechanical fuel pressure gauge. Is this even possible to have in a gauge pod in the interior of my car? I don't think I want a braided hose filled with fuel inside my car. Do people do this? Or do they only go with electrical for gauge pods?
How is a mechanical one installed? How about an electrical one?
I see that are 0 - 15 psi, 0 - 100 psi, and on a meter from 0 - 1.0. Which one do I need?
Thanks for the help.

I would not reccomend putting a mechanical fuel guage in the interior since if there is a leak there will be fuel spraying inside the car.
Mechanical and electrical are installed basically the same way. Mechanical the fuel goes through a fitting into the guage for a reading, and electrical the fuel goes into/through a similar fitting with a pressure transducer that provides an electrical signal to the guage.
I'm not sure what the 0-1 guage is for but the 0-15 is typically for carbuerated engines and a 0-100 for efi.
If you are spraying the car I would reccomend keeping the A/F guage so you can see if the car starts to run lean under the spray.

I knew how the actual gauge works but I meant, how are they installed? I assume they are just tapped into one of the fuel rails?
