Hi guys,
So i recently got a sard 280L/hr direct replacement pump for my R33 gtr and installed it quite easily. For those that havent seen these basically they fit in the standard position in the cradle and then you just attach the nipple and lower hose/sock from the original pump to the new pump. Now ever since then the car runs out of fuel at a quarter of a tank. Ive had the pump out 4 times...the first i thought maybe id curled the pickup sock up so that it wasnt sucking from the bottom so i reinstalled it and although you cant feel where it should sit in the tank i was fairly confident id got it in the ballpark but this didnt work, next i tried reorientating the sock to make sure it was definately pointing as low into the tank as possible, then it ran out at about the same point again. Next i lowered how low the actual pump sat in the cradle to try and extend it down into the tank but that didnt work and finally i rechecked all the hoses and joins to make sure it wasnt sucking air at any point...the hoses appear all fine and i thought that maybe the nipple wasnt sealed to the bottom of the pump because its a plastic on metal join so i got some fuel proof sealant and sealed the join but it still runs out at a quarter of a tank.
Now the other obvious thing is that the float is reading incorrectly but theres two things there. 1. i didnt touch the float and 2. the car is now only getting about 300km to that quarter of a tank mark where its running out when i used to get about 400-450km from a full tank.
So does anyone have suggestions, or better knowledge how to make sure that pickup is actually extending down into the right spot because you cant see down there and you cant reach under with your hand?
Thanks for any help guys, its driving me nuts having evo like fuel capacity!
