Depends on where you are going to mount it. A mechanical gauge will have fuel flowing to it through a tube. If you mount the gauge in the cab and the tube breaks it will pump fuel into the cab and you will never get the smell out. I haven’t had a lot of luck, I tried two good quality 0-150 psi fluid filled gauges mounted on the engine and both broke within days. I tried a cheap electrical oil pressure gauge in the cab and have gone through two sending units. Currently my gauge is reading somewhere around 30 psi off. One of these days I plan to try a higher quality electrical gauge and see how long it lasts.

I've got a 0-100 psi DiProcol Optix electric gauge. Works great! Very accurate so far.

If you don't mind me asking, where did you get it and about what do they run? I need to replace all 4 of my overhead gauges with some better quality ones.

I'll be looking for a good set of gauges myself soon. Not sure what to get.

I bought mine used for $100. I think they run close to $200 new. I absolutely love the DiProcols though, they match the factory dash colors/lighting perfectly. They are a good quality gauge too.

I have the Autometer electrical gauge. It ran around 200.00. It is a 0-100 psi. We have had no problems with it to date. It is a very necessary item for trucks with bigger sticks. You would be amazed at what your fuel pressure does at WOT. That is why I ended up doing a fuel system upgrade. I didn't want to burn my injectors by starving them.
