Hey guys,

Vehicle is an RB30 Patrol, carby model.
I've been having trouble with petrol not pumping lately.
It's been and on and off issue.
I initially thought it's a problem with tank pump(internal electric pump).
While I was working on something else today, the pump started working again(petrol started gushing out of the open petrol line near carby).
I think I isolated the issue to the relay thing as in the picture. It's located near the accelerator pedal, as in the picture.
I'm not certain the role thiis relay thing plays, but when it's unplugged, obviously no petrol comes out of the tank.
It also clicks, which makes it pretty certain it's a relay.

I want to test this relay thing and find out if that's the culprit.

I've numbered all the pins.

Pulling the tank out to inspect any issues is a pretty tough job under the car.
Before, I get into that, it would be great to rule out any problems before the tank.

If any sparkie guru or experienced backyard techie or anybody can give me few tips on how to approach this issue and how to test this
relay thing, I would really really appreciate that.



Thanx in double advance.
