Injection coupe fuel tank.

Recommended Posts

Evening all,

Is there an easy way to tell the difference between a carb tank and an injection tank. My car would have originally had carbs, it's a 1981 SR. However I have a suspicion the car may have had a GTE engine in before I got it. I bought it without an engine and gearbox. If it did have a GTE engine I assume the tank most have been swapped. I've been offered a GTE tank for not too much money but if I already have one I'll spend the money elsewhere.

Cheers in advance.

Kelvin.

hi. a carburettor tank just has one output pipe 8mm .whereas an injection tank also has a return 8mm stub next to it..the feed will also be larger 10 or 12mm

also if its a hatch and you have chance of a good tank i would get it as finding good ones is getting harder. coupe ones dont rust as theyre inside

Many thanks CIH for the quick reply.

I'll take a look tomorrow and see what's what.

Cheers.

Wonder could a coupe tank be fitted to hatch, would stop a hatch being a hatch, but would be option! Maybe! 

Seen a hatch metal back on seat used as a firewall on a coupe!

Well Ive just dug mine out of the shed and it's only got one 8mm outlet so definitely a carb tank. It's a shame as it's in excellent condition. I'll pick up the gte tank when I pick up my engine. Can't remember what he wanted for it but it wasn't a lot. 

Cheers.

 i dont see why not. havnt measured but i cant see the dimension between shock turrets being any different coupe to hatch so providing you have the depth and put the mounts in and hole into the inner wing. would eliminate any rust issues

No, it's a coupe tank. That's why it's survived I think.

Coupe tanks and hatch tanks are totally different shapes. You’d have a lot of work fitting a coupe tank to a hatch, it’d be easier to buy an aluminium race tank and fit that. I keep meaning to go to my local fuel tank specialist to see if he can remake a hatch tank in aluminium but I stupidly sold my spare tank that I could have used as a guide.

Seen a spare wheel shape tank, or could a swirl pot be fitted to allow use of a carb tank.
