What does this pump do?

[hwyhogg]

Mine is 1991. There is a pump of some sort on the passenger side of the engine compartment. It is mounted below the battery. I can't tell where the hoses go to yet, will have to take the battery out and the air intake. Not sure what this part does, but it makes a noise every couple of seconds when the vehicle is moving. It doesn't get any louder or worse as speed increases. It stops when the vehicle comes to a stop. It's the same noise whether it's in gear or vehicle is coasting. Anyone know what it's called?
thanks,
James

If its a gs, that'd be your Abs pump. Pull the fuse, or pull your e brake up a click or two and drive, eventually your Abs light will come on and the noise should stop and you can let the brake down. I'd just do the fuse though.

That is the ABS accumulator.

 

[nathan_carmona]

so whats that mean? lol

It's part of the ABS system. It means about $1000+ to fix it when it goes bad. lol

I borrowed this explanation because I couldn't explain it as clear as I wanted to.
"The ABS accumulator gathers up pressure and preserves it until it needs to be used. Once an emergency situation occurs, the pressure will be taken from the ABS accumulator in order to pump the brakes for you. It’s important to make sure that the ABS accumulator is always working or else your Anti-Lock Brake System will not be able to work properly when necessary." -CarTechAutoparts.com

so it means when I do my abs delete it would be worth selling?

If it still works you might get $100 out of it. Most people who have the ABS go out on their G2's don't bother fixing it and most enthusiasts want to delete it like you.
