I'm sorry to say you are wrong! The the GLSi models use an internal fuel pump and not external so you won't get a return and feed pipe coming out of the tank! So your dad on this topic is unforunately wrong...I Hope he's ordered the right one for you....

Kev - I used my pattern one for a week and did some hard driving... It cause monsterous amounts of problems with spluttering and cutting the engine out when giving it the boot round corners... So i'm sticking my my decision so where is your evidence

Changed to a genuine one and it sorted the problem. Ford tanks ones HAVE got an internal swirl pot.. When you take the sender out you can see it as it's bright yellow in the right bottom corner!
