Hi guys,

Installed electrical fuel pressure gauge, but not sure if the gauge is working right.

When the car is running (idle or driving) the arrow inside is jumping, give or take by 5 psi, non-stop.

Is this normal in mustangs or just particular to cobras? Or is this normal at all.

Thanks

...Is the gauge liquid filled?? ....If not, that could be a problem!

"Is the gauge liquid filled??" = It's not.

I should've done this already. I will post video on youtube so you can see and then post link to this.

Gauge is electrical, full sweep.

mine jumps alittle like 2 to 3 psi and my car is fully tuned

I might've overstated little bit. It counts by 2 on that gauge, so I would say it moves between 2-4psi.

Might just be an electric gauge thing....but recheck your connections & ground!

looks exactly the same as mine i wouldnt worry man

I guess it's fine, I won't be worrying about it. Just never seen this before.

I guess maybe since cobras don't have fuel return lines, that's probably why it's doing it this way.

By the way it's electrical & full sweep if anybody is wondering.

ya thats exactly what i was thinkin i imagine is pretty hard to keep a constant pressure without returning it....time for fuel system upgrade for me
