Electric Fuel Pressure Gauge Problems??

[sjbsuperman1425]

Idk if im doing something wrong or what but, I bought an electric Oil Pressure gauge to use as a fuel pressure gauge. I have it all wired up, all connections are clean and i have my sender installed in a T i whipped up from fittings from Home Depot. It doesn't leak or anything and when i turn the Key to on and the fuel pump is going, it reads "0" psi. Its hooked up between the FF and the Fuel Rail and i tried grounding it to the chassis but still nothing. can anybody give me some advice? I think it might be a bad sender, since it looks pretty beat up, but I know people on here have Electric Fuel Gauges and just would like to know if this is how they set it up. thanks guys.

oh, and i used 1/4" barbs on the T, should i switch to 5/16" or would i be ok? dont want to starve the motor?

well i searched google and came across a RX7 forum and found my answer. pretty sure my sender is bad so i think im gonna buy a new one. there is no continuity between the S-Terminal and the body on the sender.
