Hi Guys,
 
Are there are benefits to moving the tank into the boot on a MKII?
 
I am building my car for track racing and have seen guys use Capri, Datto or Gemini fuel tanks in the boot.
 
From the design it seems they may be better for fuel surge but I plan to use a swirl pot anyway.
 
Another question is if you do use one of the above tanks  (I can get a Gemini one very cheap) what's required to get the fuel gauge working.  The Gemini's sender is 0 ohms-90 ohms so how will this go with the escort?  If it won't work what is required to get the job done? 
 
Cheers,
 
Matt

Benefits would be smaller tank, more clearance for a lowered car or one with a watts link or panhard, bringing in the weight to within (or close to it) the wheelbase. In my rally car build I am using a Capri one, but I have also seem a mk1 cortina tank inset into the boot floor of a race mk1 escort... I had to get the correct fuel sender for the mk2 escort for the lpg tank and I think it was 73-0 ohms or something like that and it works perfectly (unlike my other 3 petrol escorts...)

Hi Matt,
You may want to pose a couple of questions to yourself.
What size tank do you need? I.E how many laps will you be able to do or need to do?
Obviously the smaller the tank the less fuel, but less weight. Alot of people fill their tanks to stop surging.
Will a proper foam filled or bladder style tank be required for the level of racing you intent to do?
Just a couple of thoughts.
Cheers

Hi Craig,
 
It will be a weekend warrior so I still want a big enough tank to go on drives etc...
 
If I use a surge tank the level the tank is filled to won't be an issue I assume.
 
This just seems a cheap way to go.

Cheers Nick,
 
See you at the next meeting

So, I ended up getting the tank after all on eBay for $15.
 
Whether I put it in or not I'm not yet decided but it was cheap so no biggie.
 
Given the difference between the resistance of the Gemini sending unit (0 -90 ohms) & the Escort (73 - 10 ohms) do I just need to get a different voltage regulator for the dash at the required Ohms and all is good?
 
And is the regulator the little black dealie in the photo below?
 
Cheers

Your fuel guage will read backwards - ie read empty when full and full when empty. Voltage reg is the tin box in the middle of the pic. Voltage reg is just that, keeps a steady voltage -changing voltage regulator will not influnce ohm range of fuel guage.

Yes, I have been doing a bit of research.
 
What are my options if any?
 
Cheers

Either get the Gemibi sender recalibrated (ringwood speeds may be able to help) or a stick.... don't laugh but I know of more than a few race cars with,'calibrated wooden sticks that they dip in their filler to check fuel levels (not while racing of course), and a friends old landie had a factory reserve tank under the front passenger seat that you lifted the seat pad up, unscrewed the cap and dipped a petrol smelling stick from between the seats into it..... I Kidd you not.

Capri tank was a easy fit.. sender works with the standard gauge which makes life easy.. getting harder to find but a good fit, i can still get a spare on the boot floor. Personally for an occasional track car id go for one of the plastic fuel cells with electric sender in it. That way you can use a afetrmarket gauge and still mount it under the boot floor (make a shield up for it from exhaust and rocks etc) will keep the weight down low and be lighter and foam filled will stop fuel surge etc..
