Bosch 040.. Warning

[peterwolds]

ran my EVO V with a walbro pump slightly noisy at tickover but no fuel cuts

[nikp]

Or the Apexi BNR33 pump as i understand that is a good pump, and doesn\'t suffer the same problems (And thanks to slippers selling me his! :p)

if there is no swirl pot in the fuel tank and you run low fuel levels then any pump will give probs in hard cornering situations

Apexi BNR33 is the way to go for up to 450 at the wheels it has a fuel sock as well which helps when low on fuel, I have this fitted to my current black car. no starvation problems at all even even when down to 1/8 of a tank.
The 040 outflows the existing swirl tank/baffles (what ever you wanna call it) in the fuel tank. The 040 is only good up to 350 at the wheels on my old car setup.
Warlboro is just plain nasty noisy thing ok for moderate mods on twins.
I will be looking to go back to a swirl pot and twin 044 pumps as I want more then 450 at the wheels.

Got one of these and I managed to prove it\'s a fine pump with low fuel recently - heading to the petrol station, had a play with an Audi TT (i know, hardly a fair match) and then filled up with 66 litres - less than 1/8th tank left.  This includes whanging it round a few roundabouts too...

Had the same problem on mine Rmaj.....  thought something was wrong as it happened on the way back from pips just after i\'d rebuilt it and had the engine tuned    anything under a 1/4 of a tank and it happened,....  so just kept it topped up  

I think it has to do how you mount the pump in the tank too....  need to get it as close to the bottom as possible

Are these pump made for Skyline R33 or is that just a name Apexi gave them??

[richard cash]

can someone elplain how a swirl pot works and what the symptoms are of fuel starvation. Will it kill an engine?

[BlitzBoy]

Fuel Starvation symptoms in my case was bucking of the engine when severe, when not so severe it causing the engine to lean out under boost which you may see increased knock (ie the engine light flashing). Yes it will cause engine failure in broken or cracked/warped tips. It caused my engine failure early this year spitting out a corner seal
