R34 Gtv Drinking The Fuel

[slinky-minky]

Hey everyone,

I've been having a bit of whinge over the last few days that my car has been drinking fuel but it out did it self last night.

From Bendigo to St Albans it went through half a tank of fuel, hardly any wind resistance, highway driving at 110-115kmh with no crazy breaking or anything unusual, except for the 3 minute wait at the lights on Main Rd. Tyre pressure is good, tyres themselves are in reasonably good condition, however there is a noise that I thought was wheel bearings or low diff oil and my mechanic says there all 100% but my tyres are just cheapo crap, so I filled my tank up again and it went through 1/4 tank of fuel over 10kms drive to the supermarket and back.

I'm thinking my float might be getting stuck or something because it seems to drop in large increments rather then be a continuous drop.

You could easily tell if you have a faulty/sticky float; as the amount of fuel indicated on the gauge would not correspond to the amount of fuel you put in the tank.

ie: if the gauge is showing 1/2 tank, after only driving 100km, then you fill up and it only takes 10ltrs, then you know it's the sender/gauge that's faulty. If you fill up and it takes 30'ish ltrs, then you know the car is drinking fuel excessively. It could be a faulty O2 sensor, a leak, afm, etc.

My R34 did the same when it first arrived from Japan for at least a month. I put it down to the fact the car sat around not being driven for a while and the float might've stuck in one position.
