Fuel pump WALBRO or OEM Volkswagen

My sister's fuel pump was causing poor mileage in her 2015 mk7 golf sel - it eventually failed and was replaced under warranty and the car now gets as advertised...

Reportedly the aftermarket ones don't last too long. That's why I had ultimately decided to keep the OE 14 y/o pump in the van

Since the original pump was strong and quiet I decided to reuse it as well and keep the new pump as a spare. I decided to let the perfectly working OE pump run its course.

Wonder if it's fuel related, that happened to my CC turned out to be a Fuel Pump Issues in the gas tank.

Walbro 450lph E85 approved. It outflow 044 and is certified to run E85.

I have a Walbro intank pump, I replaced my oem when i though it was bad a few years ago.

today i upgraded fuel pump to an intank Walbro 255LPH and tested with 100% e E85.. Its really strong now.. it would be really interesting to measure the WHP now... im a bit blind when it comes to hp... but the car really give you a ride i can tell you that.

I had my inline pump next to the fuel filter and it was way too noisy, ended up moving it to the engine compartment and fitted it inside some 3" tubing with insulation around it, just a slight whine at idle can be heard and none as you are driving

since the original pump (aged) is hardly safe over 200whp imo; esp with increased rail pressure.

No it will NOT work with the current pump....the R32 pump will burn out as the fuel pump controller pulses the pump which burns out the brushes.
