Noisy Fuel Pump

[stubbie]

Which Bosch fuel pump do I need for a 1999 Subaru EJ 25 SOHC?
I currently have the blue RJES unit fitted but it's too noisy and hums louder than the engine when at tick over. I have tried mounting on rubber / left it hanging in mid air with foam wrapped around but all to no avail. The pump is not cavitating and the tank is clean.

I have the same issue, and recently got a bosch unit (think 009) off a specialist performance pump supplier along with a new filter. Problem is, still noisy! The conclusion being that its noise thats normally closer to the engine and not just behind you. I have run the same route as you, foam, rubber, free hanging and I am about to strip it back again to try a new set up using exhaust mounts. Just don't expect a massive reduction in noise by just switching the pump. The ultimate solution (cost no object) is a small pump fitted further back next to the engine lifting the fuel to a swill tank next to the engine with another pump for the final feed, £250+ though!

I have had the same problem. Richard has sorted it as he does. Excellent customer service. Talk to him.

Richard was very helpful to me also, I'm probably expecting to much

Just realised I left this open. The solution is to ditch the blue unit and fit a Bosch unit, they look identical apart from the colour but the Bosch unit is super quiet, so quiet that you can hardly hear it running.

Hi, Sorry to revive this old thread, but my Fuel pump noise has ALMOST made me cut the damn thing out, drink the petrol and try to P!$$ the fuel into the injectors myself its that annoying !

Please does anyone know who "Richard" is or What "model number" of Bosch pump or better still PLEASE where can I buy one ?


Thanks

Hi,
The solution that worked for me is to fit a later fuel tank normally used in fuel injected models, it has a larger bore out pipe. I then used a bosch pump, with mount and competition filter from the guys at Glencoe http://www.glencoeltd.co.uk/" onclick="window.open(this.href);return false;
works great, no more noise.
