Petrol Pump in speed six getting Louder, WHY??

[JAKIRE]

HI all
I have noticed in the last few week my Petrol Pump is sounding Louder, in my speed six cerb, does anyone know why?

I have found that pumps sometimes get noisy shortly before they fail.

I hope not, Its a new pump I put it in about 7/9 months ago

cheers

What was wrong with the previous pump? Put another way, if the failure was the result of debris in the tank, or a blocked pre-filter, what's to stop the replacement going the same way?

Had this too and wasn't the pump!

Solved by local fuel-injection expert Mike Evans Motorsport; on mine it got loud after running for 40mins or so. It was heated-up fuel on the return line to the pump, which heated it up and made it vibrate a little more making the noise.

Solved completely, mainly by adding plastic coiled tube-protector (think available at Halfords etc?) on the supply and return lines where they run close to the engine, I also insulated the fuel rail using fibre washers.

You're welcome. Of course it may still be the pump, but this is a lot easier & cheaper.
