[QUOTE="fabianyee, post: 151655, member: 6"] Not sure if that's a good practice to stick to, cause the pump motor may be hanging high and dry once the fuel level past the 1/4 mark. I hope we won't hear a 'fuel pump kaput thread' from u in the near future. Hmmmm.. Wonder how much is a E46 fuel pump? A new E30 318i fuel pump cost RM800. Would the E46 fuel pump cost less than that? EDIT: I notice the E30 fuel pump motor has a foam tube covering the motor. I reckoned it has capillary effect to soak up fuel to cool the pump motor. Why? cause the motor won't be submerge all the time so it needs something to cool it when it's not fully submerged. Something like putting a cool towel on your head on a hot sunny summer day. The point is, when the fuel level is too level for the foam to soak any fuel to cool the pump, then the pump would be running hotter without any cooling. Over time, it'll cause premature wear and tear. [/QUOTE]
