bosch ext. or supra pump

bosch or supra single pump?

I am looking for a single pump that would be an alternative to the double pumper and the a1000.
 
Neither of those pumps ( Bosch/Denso ) will give the volume of the A1000.

Walbro is fixing their pump issue so stay away and we don't know anything about your car so hard to say what would be the ticket.

The Denso is a stronger intank pump than the Walbro to start and more reliable. You could always add the 044 Bosch as an inline if you needed more volume later on, that could be an option.
 
I'm running a Bosch HV external pump on my hybrid with 50/50 gas and E85. No issues so far after couple months.

A buddy of mine runs straight E85 in his Porsche with Bosch pump over a year now no issues.
