Fuel Tank Depth...

[Bassfiend229hp]

Anyone know offhand what the depth of the fuel tank is? Just trying to work out what length of fuel sender to order and I don't have the car anywhere around to measure...

I could (of course) use a float type sender but I suddenly have a hankering to use a dip / pole sender and they're made to length. I *THINK* I can get a 350mm long sender in there but there is a 334mm long version as well...

Is yours the allow tank or the later bought in type tank, what year is the car on ? Also the rod sender may not match your fuel guage , I have sent mine back to unspeedy cables for a new movement to match my sender, I tried one of those fuel wizard units bit it was pile of pants and not linear,

Let me know and I'll have a measure as I have a fuel tank in the garden

My 97 car took a 370mm VDO dip tube (ally tank wider bottom than top); BUT make sure your gauge will cope with the VDO resistance scaling and 'direction' of scaling curve- this has been a major source of grief with my SPA gauge, which really doesn't like it (and is supposed to be completely 'intelligent'/programmable)

If you need a dimensioned sketch of the tank, I can ping one over that Phased kindly did for me a couple of years ago - PM me an email addy

Mine's a '94 with a standard TVR-fit tank ... didn't know there were different tanks fitted by TVR themselves but I guess I wouldn't be surprised by there being so!

The Smiths gauges I've got use a 10-180 ohm sender and I found some dip and pole-type senders in that spec:

• chuckle* ... Gavin at CAI did say that he could configure up a Smiths Flight fuel gauge to use the VDO gauge senders if I wanted.

In that case I'm hoping that if I use a 350mm sender then there'll be a bit of "reserve" when the gauge hits empty...

(I'll drop you a PM...)

Be careful Phil.

The sender TVR used actually works back to front to the way most senders do, in terms of resistance vs gauge needle high/low position.

Check it with a meter and watch how your gauge responds when you move the sender arm, you'll see what I mean.

Tube type VDO senders are the best performers with regard to slosh fluctuation management, but you may need a fuel gauge wizard from Spiyder Design to solve the back to front resistance issue and make one work with your TVR fuel gauge.

I learnt all this when I tried to find a sender for my bespoke 5 gallon auxiliary petrol tank used in my LPG conversion.

Saying that I have Caerbont gauges and I seem to remember you built up a set of nice after market gauges a while back?

Yup ... 2013 I started that dash!

...and it's still not in the bloody car ... yet!

Mind you - the car's still not on the road again (yet) either but that project is starting to be driven on again (if you'll pardon the pun) so hopefully not too long ...

Finally ordered the custom AFR gauge last week, ordered up new water and oil temp senders, oil pressure sender (wince!).

The last sender (hopefully) was bought last night...

Just got to find a couple of "nice" pushbutton switches to mount in the dash that I'd forgotten I needed to adjust the clock and switch the odometer displsy...
