Rear wing fuel tanks - fuel gauge?

[roamingyak]

I have a prototype rear wing diesel tank from Allisport.

Just checking with all those of you out there who also have one - when you fill up completely, do you have to use about 40 litres before your fuel gauge starts to drop at all?

Tank will be coming out soon so an easy chance to replace bits inside the tank etc.

That is correct for the tanks that connect inline with the filler hose.

Yes.I have had rrear wing tank(35l) for 2 yrs.Used and monitored all the time and gauge does not move until 35l is used.

cant remember what make mine is, its been about 25+ yrs , holds approx 45 L but there is a bottom balance pipe , and the guage reads usage as normal , ie as the tanks content drop so does the guage . there is no plateau stage . Its a V8 but still doesnt use the fuel up so fast that 35 litres is gone before the guage catches up

I use a Frontrunner 45 liter wing tank, and the gauge starts reading after some 40 liters.

I've got one as well... but it's sat in the garage. needs "notching" so it'll fit around the rear cage leg that bolts to the crossmember.

Needs plating too, as it's rusted through in places. time for a rebuild I think.
