Hi,

I was wondering if all pressure gauges were the same? For example, I have this generic gauge here:

that originally was used to test water pressure. Its a mechanical gauge that goes from 0-160PSI and looks to have a 1/4" NPT threaded end for various fittings. Can I use this as a fuel pressure gauge?

Thanks for your help.

 

yep shoulld work just fine.

 

it'll work. the cheapest $7 pressure gauge will work. I wouldn't leave it as a permanent solution, but for tuning purposes it will get the job done.

 

yeah... don't mount it for permanent use. if it was designed for water the gasoline will likely destroy the seals in it fairly quickly and result in a high pressure fuel leak. engine bay fires suck ****.

 

Ah, thanks for your advice everyone!

 

i got mine rated for hydraulic seems to be holding up ok.
