Hi Chaps,need a little help please.
Need to replace my fuel tank on my 90 spec 1989 mfi s2 esc turbo.
removed old tank and it has the slim type senderwith a white float.
ordered another tank,its arrived but its got a bigger hole on top with a different sender and a black float.
do you know what the difference is and if the replacement will work?

have i got the wrong tank on at the moment? should it be the big sender one?
is the slim sender one for efi?

if its compatible gotta spend hours trying to clean it out cos the prat who sent it to me didnt bung the holes up,sent it in a box of loose polystarine packing,and its all got inside the tank,been melted by the old remains of fuel and its like glue everywhere.

so basically,need to know if it will defo work before i assign my day to sortin it.

thanks my lovely rs brothers

 

ive got a spare mfi s2 tank and sender sat in the garage and its painted gloss black aswel ... if you need it otherwise its going in the bin

 

rs mark if he's not interested in the tank i might be depending of postage price mate cheers

 

to be honest i havent got the time to sort out postage but if you can sort a courier then i will have it by the front door wrapped up ready to go....

 

Hi rsmark.
Appreciate the offer of a tank buddy.
Do you know if the big hole and small hole types are both compatible?
If yours is mfi i guess it will work on my mfi?
And i in milton keynes so you not too far from me are you??
thanks fella

 

im not sure mate but i took it off a mates 250bhp s2 and worked fine so im sure will fit yours no problem and it was a 1988 model so im sure will have no problems im thinking the tank you got must have been an efi one

 

how far you from mk mate

 

not sure mate post code is rg12 7qb

 

ooooooh.thats a 140 mile round trip for me.
I`ll leave it for now fella.
Really apprreciate the offer mate,you a good chap

 

thats cool its there if you need it

 

thank you

 

somebody must know the answer to this.come on guys.
pleeeaasseeee

 

The one on your car is the correct tank with the smaller sender so you will need to replace it with the same if you want your fuel gauge to work correctly

 

I have connected the fuel sender and manually played with it and it's very accurate on the guage. Can't see how it would be any diff on the car. Guess I'll have to try it

 

IIRC all S2's have the same tank except the very late ones (89>) with the small sender hole.
I think the pipework inlets/outlets are slightly different too so they are not compatible.

 

Basically there are two types of tank for the mfi s2

88 Spec - large sender hole



90 spec - small sender hole



You just need to swap the 90 spec one you have for the larger 88 spec one - as you see from the pics the pipe locations are slightly different and the sender size is completely different.

** NOTE ** A large number of 90 spec cars did still have the 88 spec tank on it tho so its not unusual to find an 88 spec tank on a 90 spec car (used to clear ford stocks at the time as it wouldnt be noticed I assume)

Simples !!!

 

good info there s2turbsZVH also worth noting the efi tank would have no provision for the k-jet pump underneath as it runs an internal pump.
