Don't think we've had a Fuel Pump Thread for a while...

[Dave2P]

... so here's one ...

Ran the Nob up to Brands today; round trip of about 260 miles and pleasantly warm... During the journey home became aware of the "angry bees" sound; not sure if it suddenly came on or gradually got louder as we were a) on the motorway and b) still had ears recovering from the GT cars.

From a quick scan there have been many discussions in the past but what's the "best / latest" thoughts on why the pump gets noisy / what to do about it / replace it with?

FWIW, the fuel pump wiring was upgraded at the last service (about 600 miles ago); could that conceivably be pushing more current/amps/magic beans to the pump, or is that completely unlikely?

And, finally, does it just get noisier until you get sick of it or does the pump fail at some point?

TIA, Dave

cavitation as the fuel warms up

Thanks Adrian - this looks like the right answer as no angry bees detected this morning.

So is the ultimate fix to re-locate the fuel pump (when it's time to upgrade), or will improving the engine bay cooling generally be enough? I have the tunnel cooling mod done, so time to look at venting the clam?

Thanks for the clear explanation Andy! Evidently I need to do a bit more reading (of the older threads) but looks like nothing to worry unduly about right now.

Cheers both.
