Is anyone elses fuel gauge all over the place

[YAKDUZI]

My fuel guage fluctuates constantly. It can go down by a quarter of a tank and then just go back up agian, so I never realy know how much juice is left. Also it will only fill up to 3/4 full on the dail? any thoughts?

They all do that mate
Seriously, the TVR fuel guage is the least accurate I have ever seen. Your best bet is to do figure out by your mileage. I can't because my speedo is out of action, so I'm always three quarters filling my tank, just in case. Otherwise park on a flat road and wait a couple of minutes to settle.
I'm not sure about it not going all the way to the top though. Probably just a unique feature to your car!

Mine does that around bends, up hills etc, is that what you mean?. Some makers have better damping than others if you get my drift.
Sod to top off due to the small pipe between the 2 tanks. Have to wait a while at the pump to settle. I never let it go below 1/4. I have seen it in the red but at the rate mine drinks it its the 1/4 I look for a fresh supply.
Sure someone else drinks more

Blocked swirl tank or interconnecting pipe between the two tanks if it is accurate or pan-dimensional fuel gauge that doesn't quite know what reality is. Standard fit !

I always work on the basis that when the needle stops bouncing, there is no fuel left.

Out of interest what is the most fuel anyone has managed to get in their wedge? I have never run out but from memeory it is just over 43l.

I've run mine out before and it took something like 53 ltrs to fill it, a rule of thumb I use is when the needle has stopping moving altogether, there's about another 2 gallon left / 30 miles to go which still allows for a reasonable safety margin.

Used to get no more than 35 litres in at any one time.
filling up involved rocking the car to getthe fuel to leave the filler pipe.
Peninsula replaced all the fuel lines with bigger bore ones, and replaced the filter and swirl pot.
Now I get 45 litres no problem, and the possibility of an extra 5 litres if I rock the car.
I also carry an extra 10 litres in the boot to extend my range.
Typical range on one tank is 225 - 250 miles ( managed 300 when cruising through france 2 years ago, but that was taking it easy )

I ran completely dry - left it to sit overnight on the chance something would drain back - still dry in the morning and then it only took 36 liters, including waiting and shaking during the filling.

I understand blocked transfer hoses effecting the ability to fill both tanks but since the swirl pot and filter appear to be downstream of the tanks, would changing them have any effect on getting the full 49-50 liters in?

Thanks Grady

I think in my case the connecting breather was kinked .. this the tanks took a long time to equilibriate.
I upgraded to bigger hoses to solve the problem.
The swirl and filter were changed as a matter of course

[grady]

I shouldn't ask this without looking first but I want to get mine sorted out and so while we are on this thread...

I'm with you all on blocked or kinked hoses casusing problems but assuming that the interconnecting hoses slip over and clamp down on fixed nipple(s) coming off the tanks... how do you fit "bigger" hoses? Grady

[wedg1e]

I thought the Wedges had 2 tanks each of 6.5 gallons, which is (ahem) 13 gallons or as near as dammit 60 litres.
Now I'm a complete skinflint, so there's no way my TVR has ever had full tanks while I've owned it

Cruisin' ... you know 80mph, boot full of Wine & hardcore Euro P0rn, Good tunes on the radio and that V8 growl as a backing track

Sorry, I should have qualified my first posting.
I have increased the diameter of the host that has been used. I had a new set of tanks fitted, with larger diameter npples

[grady]

Gotcha, Thanks

Notice I didn't ask about the new tanks, some things are better not known!)

My fuel gauge fluctuates a lot too. However if you connect the seat belt it sometimes registers normally? . Why I don't know, possibly an electrical/earthing problem. When it gets to a 1/4, I re-fill just to be safe. I know that doesn't help you, but it maybe an electrical problem.
