Thanks for your help guys
No it is not leaking from the boot it was leaking underneath the car. I also checked the boot when i saw it leaking and it wasnt leaking from the boot next to the battery. I drove home and checked if it was leaking but it stopped.
Also, the guy i had bought the car from had an aftermarket fuel tank or surge tank or whatever it is but he removed it from the car so i was thinking he didnt remove it correctly thats y it is leaking?
