Fuel Pump Upgrade

[KPM Motorsport]

Dave, are your intanks (Walbro & 1000hp ones) guaranteed to prevent surge? Even at really low figures I.e. 20km DTE?

Or is it still advised not to 'trash' it with less than 1/4 tank?

Thanks!

Yes 100%.

All Streetfighter systems have been on 100s cars now for over 3 years.

We have had not 1 surge issue ever reported back to us.

The reason for this is that they a a properly engineered product that has been fully desihned and therafter tested for , flow volume, anti surge and correct system pressures.

Unlike a surge tank it is a complex design that allows perfect manners.

Not recommended however on testing, we raced a car around Malalla race track with less than 5 litres in the tank . No surge and the fuel pressure remained perfect until we ran out of fuel on the third lap.

price?

Awesome thanks for the response guys

Assuming you just change the in tank pump to a much higher flowing one, will you need a retune?...(assuming you're keeping the stock regulator)

Just want to know if I should be upgrading the pump at the same time as the injectors.

[T-Rex]

Also curious about this, surely it would change the dynamics of the fuel pressure? The kpm one comes with a reg so would that make a difference as well?

[FiftyOne]

It should be fine I would think as the pressure would only be more consistent with a stronger pump. Re what happens in the top end from a tune that's trying to work around falling fuel pressure, it might run a tad rich, but it should be fine. This is all assuming that the reg is swaped to match the pump flow

It comes as a direct fit , properly engineered package, to maintain correct fuel pressures and supply volume. Includes.

hi just wondering would I need to re-tune after installing the walbro? its on 370rwkw and sometimes surge now

thanks

if fuel pressure remains the same and your car wasn't previously tuned trying to band aid a poor fuel system, then this system shouldn't need a retune. However, id recommend getting it on a dyno just incase.

Does this no surge recommendation differ for ba/f to fg?

As in the bf sedans the swirl pot doesnt sit very low in the tank
