Just wondering what the advantages of changing to a Walbro fuel pump.

I have a 2000 bugeye with a few mods.

Decat
Piper induction
Remap

Would a fuel pump be worth changing and would this need another map.

Thanks

The only reason to change would be if your standard pump was becoming worn or faulty and it would need the fueling checked if this was the case, I would have thought your mapper would have raised this with you.
The standard subaru fuel pump in good shape would support any mods on a standard wrx engine. My standard pump maxed at 420hp on 650 injectors, this on a 2.5 forged build.

Not sure if a Bug WRX pump would fuel 650 injectors ?

Not worth changing then unless I have any problems in the future.

Thanks for your time

Shaun,
thought bug would be similar to the blobeye, circa 190LPH?
I inadvertently found the limit of my standard blobeye pump (which for the past 4 years I thought it was a walbro 255, as fitted and paid for to a Mr Chris Davies), injectors maxed the pump but then fitted a RCM 350 and car made 441.6hp at 83%IDC.

Just bare in mind your current pump is 12 years old, if nothing else it's worth changing just for piece of mind.

Also worth considering a HRC 255 instead of a walbro.

No point changing - not at all.

Ignore this ^ Your pump is 12 years old and won't flow as well as a walbro

Your Engine is 12 years old - get a new one .....

Your Gearbox is 12 years old - get a new one .....

Your Steering Wheel is 12 years old - get a new one .....

Your Door Handles are 12 years old - get new ones .....

Fuel Pumps don't suffer age related failure - or, in fact, any failure!!

If you listened to the hobbyists on here you would go to bed crapping yourself - believe me, you are absolutely fine with the Fuel Pump you have!!

Fuel pumps dont ever fail

a change of fuel pump should be done in consultation with the person who maps the car.
The fueling on my car was cut back by 18% once the new pump was installed.
