icapture Posted January 26, 2010 Share Posted January 26, 2010 Bought this fuel pump on eBay a few months ago and have recently got some time to work on the Z. I am attempting to install this fuel pump but there are 4 hoses on the Z, and only one inlet/outlet on the fuel pump. I forgot to take pictures of how the stock fuel pump was set up, and I left some of the stock fuel tubing at Napa (had to buy some new fuel line since I had to cut the old ones off) so I cant really try and just reassemble the stock set up and start over again. Can someone help me out with this? Which lines go where on this new pump? Area in question, which hose to I attach to the new pump? New fuel pump attached to old fuel pump bracket: Old fuel pump: And what is this? Fuel filter? Quote Link to comment Share on other sites More sharing options...
ThreeMoneyJ Posted January 26, 2010 Share Posted January 26, 2010 That is not a fuel filter. It is a fuel damper. It's there to prevent pressure surges. With a good adjustable fuel pressure regulator and pump you wont need it. One of the lines from the gas tank to the pump is your fuel feed line. One of the lines from the engine to the gas tank is your fuel return line. The other two should be vent/vapor lines which go to your liquid/vapor seperator near your gas filler neck.

cockerstar Posted January 29, 2010 Share Posted January 29, 2010 The pump you had pictured is an in tank pump, and won't work as mounted. The one hose coming out of the top is the outlet house, where the inlet is the white screen. Quote Link to comment Share on other sites More sharing options...
