Hey guys,
When my car is at half a tank, and Im driving hard through right hand corners, the car splatters, and farts, till its straight again, im thinking its the fuel slushing around in the tank, Is this a common thing? And how would one rectify?? Surge Tank? I dont know how they work, or if its a costly mod.
Help much appreciated!!!

not costly. maybe 150 for a surge tank. you will need another fuel pump. so theres probably another $300 there. or use your old lexus pump in the tank as a lift pump and get a vl turbo as an external. then you'll probably get out of it for $300 all up.
how does it work.
lift pumps lifts fuel from tank into a surge tank. surge tanks are usually short an narrow and you have the fuel out of it coming from tha back siude so gravity of a launch forces the fuel to the next pump and it then pumps fuel to the rail.
easy peasy.

Most cost effective and least complicated solution is to get a baffle/well that surrounds your fuel pick up, welded into the bottom of your fuel tank.
This will keep fuel around your pick-up when you hit the twisties. These baffles differ in design, from the maze type to ones with holes drilled in the sides at various spots and of various sizes, that control how much fuel flows away from the pick-up while driving. Holes obviously allow fuel in when the tank in being filled too.
Find an accrediated fuel tank repairer to do the job. They will attach an approval plate to your tank to certify the work.
If yours is done like mine, a small square section of the tank directly below the end of the pick-up sock was removed, the well/baffle was welded onto that, and then that section was re-welded back into the tank, so the baffle surrounded the pick-up.
Are you sure you do not have an existing baffle in the tank orf that your existing fuel pump, if it is an in-tank one, is not one of the latest designs which see the pump sitting inside a canister / well that works to 'trap' fuel around the pick-up as the tank get empty ?

Thanks, can I ask how much it set you back (If you dont mind!!)
I have no idea if there is an existing baffle.

lets think about this logically.
drop the tank takes 15 mins, change to a small standard lift pump, the one his mechanic took out. thats done in 30 mins
use his walbro and the next pump.
mount a surge tank 25 mins, buy some new fuel line and clamps say $40 max. job is done.
think about the amount of time to take the tank out. wait for the fumes to go away before welding, maybe a couple of days.
then get some one crazy enough to weld it. then pay some one to put it back in.
i think the logis speaks for itself here KOFFEE

This seems strange for a late-model EFI car; there should already be adequate baffling in the tank. Surge tanks are generally only required on cars that were originally carbeuretted. My 20yo Supra never surges, and believe me it sees its fair share of hard cornering!
Maybe you should check how your fuel pump is currently mounted in the tank, it sounds like something dodgy is going on.

Wait on new brain storm thanks to norbie Return lines only go half way into the tank your mechanic hasn't hooked up the two fuel line backwards has he.

check the fuel pump relay and circuit is all working and earthed i used to have this in my RA40 before i fixed bodgy fuel pump wiring at the relay which was also wired by so called 'professionals'
anyways over bumps the fuelpump would sometimes lose power and the engine would stutter.
also norbie is correct, there shouldnt be much need for a new car to have a surge tank system put into it. it should be adequate already.

Was not talking about the pump having a return line. But the tank has to have a return line. Which pump did he take is it inside the tank or an external one.

To weld up a fuel tank, drain flush then run a pipe from the exhaust of another car, there is not enouugh oxygen left for ignition. Guy down the road from where I used to work did it all the time. he is still alive.
