Default Fuel pump relay 1999 Olds 88 3.8

I need to pump out some gas out of my car, Which one of the relays in the attached photo, do I need to remove, so I can jumper the pins and get some of the gas out, to put in my other car? I attached a photo of the relays my car has, numbered them 1-5. I did not see any markings on the relay center cover

Reason for the question: The crank sensor shot the rapids as I was making my paper deliveries, and need to take some gas from the Olds and put in my backup car to drive til I can get my Olds fixed in 3 weeks when I get paid

Just turn on the ignition. Better than messing with stuff and then having to fix that as well. All of that stuff is delicate and old by now.

I'd use a hand pump through the filler neck or hose and siphon. Mitchell shows the FP relay on the right IP fuse block.

It probably has an anti-siphon thing in the filler neck like my LeSabre since all those parts are the same..

I did that and it worked. Pumped the gas out from fuel rail through the release port on a fuel pressure test gauge to drain the tank before replacing. I thought the pump only runs a few seconds if the engine isn't running. Why did it run continuously?

Cool!

Maybe the new owner will bring their questions here and we can keep fixing it!

GM installed a single wire with a GREEN connector next/near the battery on vehicles around 95. If you apply 12V+ to this wire, it bypasses the FP relay/ignition etc and sends 12v straight to the FP. I found this on my 95 Bonneville.
