fuel surge/half tank of fuel...

[Aubec]

COuld it be a cloggged filter because of running without a sock?  I.e. the pump can supply enough fuel to keep the engine going up to full boost, but at that point it just cant flow enough through the dirty filter so it feels like fuel cut but is just fuel shortage?

we are doing a custom/pikey collector as well i\'ll let yeall know how it goes :Giggle

2009 is so overrated...

I think you\'ll find that the gtr pump is fine even with very little fuel in the tank. You may want to check how it\'s been installed.

Brian is right.  I have a GTR pump installed by RE:WORX, it had been modified by HKS in such a way that it doesn\'t require a swirl pot.  Speak to RE:WORX

[AtomicRex]

The reason the swirl pot is there, and without wishing to sound too patronising, to keep a head of fuel when the fuel level within the tank starts to decrease.
 
I don\'t see how a modified fuel pump can remain in a head of fuel???

I also have that same pump. When i first got the car it used to fuel surge awfully as soon as it got to half a tank.
 
ReWorx fitted this same pump and I have never had a problem since; i can run the tank until it coughs empty.
 
This is on trackdays and sprinting, so its hard use.
 
I asked about swirl pots and such and they said i wouldn\'t need one if i put this pump in. They were right.

hmmm, well i have just bought a 044 to try and cure this problem and do something with my setup, now thinking i should keep the gtr pump :confused:

do you know what pump you had in there before andy??

[MaLicE]

i run a 044 and have no probs

i can try taking my pump out to see how its fitted if you like?

there must be a right and wrong way to fit it for so many people to have surge problems...

Im using the r33 gtr pump with 1650 secondaries, aeromotive reg and single tub, Not seen any problems yet but I did fix the pump about 2mm off the bottom of the tank with the standard sock fitted directly to the bottom. I\'d say proper fitting is the key also worth checking the live and earth at the pump

[karl_tate]

cheers for the offer malice, would be good if you dont mind.

if you look at the first page you can see how my current pump is fitted to the standard holder. maybe the gtr pump is too high, i dont know, have never looked right into the tank to see where my pump sits.

If you don\'t have the right kind of filter you will most definitely magnify this issue with the bosch 044.

Ful startvation isues will be magnified if you do not have the right kind if pre filter when using the bosch 044 pump.
