Run one massive pump, if it fails the engine just cuts out. Its a safer option..
I'm sure Kieron may have a better idea, but thats just off the top of my head..

I have a walbro in tank.
The only time i get the surge is on track,
I may leave alone and just make sure I have over half a tank of fuel.
pulsarboby said:i have purchased an attain swirlpot with an inbuilt walbro which keeps a constant supply of fuel. the attain tank is around 10'' in lengh and around 3'' depth but is constantly pressured with fuel!
these are also easy to mount as they are small and take up minimal room, ideally fitted under the bonnet on top of the battery tray
if you need any more info then pm me and il give you more details on them!
Bobby what flow/power figure does the walbro safely max out at?pulsarboby said:yep thats the kiddie!
havent fitted mine yet, but will do before the cars on circuit.

I work it out at 582hp at 3Bar
Ahhh interesting forgot about dialing in the extra boost must take another look at it tomorrow.RishiGTiR said:Now remember that its 550 - 600bhp odd at 3bar base fuel pressure.. In reallity your rising rate fuel pressure will be up at 5bar when at full boost achieving 550 - 600bhp.. Walbro will be way past its limit there..
You are looking at a safe bet of 450bhp with a Walbro
