Well to add it's only when it's fully warmed up. Before 210 it sits comfortably around 50 psi but when warm it's at 15 when my foots on the gas but if I'm idling it's at zero. Sound like a oil pressure sending unit? I'll be able to check the actual pressure tomorrow

What would cause a flasher relay to go bad? I know they are heat coils that function based off of the contact getting hot so that's how it makes a "flash" but my right one went out in the relay.

Its plug and play although it'd be good to put some inline fuses on the positive wires that supply the power to the relays. Get those from a parts store.
