New Bosch Fuel Pump - BR540

[hybridtheory]

Hi guys,

In the market for the fuel setup, and these just got released apparently, Bosch BR 540. Apparently they are E85 rated.. Thoughts? Looking at the link below it states 'Improved E85 tolerance through internal design and materials'. Not sure bout the word 'tolerance' - To me, it screams out 'I'm not compatible', and that it will still fail when running them, but however, will last longer? I understand this is an issue with the 044's, where they dont seem to last very long on E85.

Looking at the chart, it flows a tad under 400LPH @ 70psi which seems pretty dam good. I wouldn't mind getting 2 of these perhaps and stage the 2nd pump to come on at say x% duty cycle or boost, as long as its suitable for e85.

Looks good, certainly guzzle a bit of power. i dont recall the 044 being so high current draw.

Yeah, although, comparing that to the Walbro equivalent, its almost on par, even tho I think the Walbro chews a tad more, not that it really matters.

Wonder if 2 of these puppies will fit in the aftermarket industries surge tanks
