Fuel Pumps?

[jameswallace. 8]

Does anybody have any experience in aftermarket fuel pumps? Need a new one for my gti6 just wondering if anybody has had any good experience with aftermarket ones or if standard is the way to keep it??

What are people using on theres??

planning to change the one in mine for a 340litre per hour pump wednesday..

A good standard will suffice, in good fettle they will supply enough for 280 ish on a n-a engine, thought i cant recall the lph figure, i wouldnt go too high, as you risk heating the fuel up

[Jolly Green Monster 51 1 Cars]

Fuel system pumps fuel to the engine and then it flows back to tank, higher rated pump wont heat the fuel more than a standard one

[jameswallace. 8]

Is that a standard 205 one or a standard 306 one??

205 one runs a Na gti6 fine. I'm running a 255 lph walbro one with my charger. Theyre not a massive hassle to fit.

the 340lph I am hoping to fit tomorrow is same size as a walbro.. I presume the fuel tank access is in the boot somewhere and it lifts out as a cage with pump in?

Yeah its just under the rear seats dude

Technically yes it will, as it has to push x litres extra over the fuel regulator, this does create some heat. In practise I doubt you'd tell any difference.

Plus also the argument that it runs through the fuel rail quicker gaining less heat soak.

Plus the higher rated pump will run cooler as its not being pushed

[Tom Fenton 1,561]

It is heat generated by pushing the fuel over the fuel reg. Simple thermodynamics. The heat does not come from the pump or heat soak.

Have found drops in measured fuel temps by insulating fuel rails away from the engine/insulating the inlet manifold. Agree the reg adds heat but also an idling engine with fuel rails sat at 70c does also heat the fuel.
