ok i've got most of this sorted out in my head but theres one thing that i can't get a straight answer on.
The surge tank i have has one pipe on the top, one pipe on the side near the top, and two on the side near the bottom.
At the moment i'm triying to decide where i should hook up the return line from the motor to the surge tank. Is there bubbles in this return line?? One guy i talked to said that there is bubbles in this line so i should make it go into a pipe near he top of the tank so it doesn't aerate the fuel in the surge tank! If i were to have this line going into one near tyhe bottom of the tank will the head of fuel in the tank lock up the return??
Basically i'm trying to fix a leaning out problem by changing the setup installed by a previous owner! This setup has a return from the motor to the surge tank but no return from there to the main tank. the return from the engine goes to the pipe on the top of the tank and one of the bottom pipes is blocked off. I want the return to the main tank to go from the top pipe so the return from the engine has to move. I want to know if it will be fine if i just hook it up to the blocked off pipe near the bottom or whether i need to move the one on the side near the top which is the intake! yes this surge tank is funny becuase the way i see it one of the pipes near the bottom needs to be at the top to stop any shite from swirling off the bottom, but this is what i have so i need to make the best of it.
Hope that this confuses the hell out of you!!
any help would be appreciated!

i sort of know what you mean.
you will need to have the return to the main tank near the top. i dont think there will be a problem with having the engine return near the bottom. there wont be enough pressure in the tank to force fuel towards the engine via the return.
the only down side is that there will "hot" fuel near the feed to the main tank.
i would get a new tank with the correct positioned lines, but if you cant then i guess you will have to use the setup as stated......
Run the return line back into the original fuel tank if you can, otherwise, run it back into one of the top tubes.
Or as slide86 stated, get a surge tank that has the correct fittings where you need them, they aren't too expensive.
if i run the return from the engine to the main tank will i need to run another return from the surge to the main tank as well?? Cos i would think that this return would be needed to allow any air to bleed out of the surge tank?
This would mean i would have two returns going into the mian tank. in this case would it be ok to hook the return from the surge up to the breather pipe. My breather pipe goes up to the engine bay where it is blocked off cos i don't have a charcoal canister! It's so good living in tas!! does any one want to pay me an unrealisticly high price for a faulty surge tank so i can buy a real one??? This model is particularly good for those cars that you don't want to run properly
why not just have the engine retur go to the surge tank? and how can u have a fulty one lol?
