Where is the fuel pump fuse at on gmc safari van ?

fuse?? I think you are talking about the fuel pump relay. go to your fuse box and look for black box that is about 1x1 and the diagram on side look like football play with an 85 on it. All my fuel relays for my pick up, every last one has the 85 trap diagram on side of it. There's no reason why it wouldn't for your van. I get mine out of junk yards. no need to pay a bunch of money for a little part like that. Sine you already know your fuel pump relay needs to be replaced, right). btw, it doesn't take 12 volts to run a fuel pump and get fuel to the block! nothing I need to start talking about! LOL good luck
