Default e85 inline pump?

Need to find out what a good inline pump would be for e85 on a heads cam car and a 150shot. I was wondering if the bosch 044 could do it?

Short answer is yes, long answer is no (how long?).

I say that because you will find people doing it on the interweb, just like with the Walbros. It works, the cars haven't blown up yet, nor have there been to many failures.

They won't warranty the pump on anything but standard petrol (maybe up to 10% eth mix?)

Here it is from the horses mouth:
From: http://apps.bosch.com.au/motorsport/.../fuelpumps.pdf

Bosch Fuel Pumps are designed for use with standard grade petrol. Subject to statutory warranties, Bosch does not warrant
the performance characteristics or specifications of these fuel pumps if they are used with Alcohol or Ethanol based fuels or
fuel additives that are corrosive.
BUT, they continue to say:

Always follow the vehicle manufacturers fitting / replacement instructions. Before fitting a fuel pump the following checks should be
undertaken.
• Ensure the entire fuel injection system is clean and free from contaminants.
• Ensure that the correct fuse is fitted. [ use manufacturers recommendation ]
• Inspect and fit a new fuel filter and in-tank strainer to the system. [ use only recommended parts ]
• Vehicles operating on dual fuel must have a quarter of a tank of petrol at all times.
• It is recommended that the vehicle be operated on petrol at least one day per week to keep the system operating correctly.
Failure to operate your vehicle in this way can degrade performance due to stale fuel and the formation of gums and varnish in
the fuel system.
I'll be getting a materials list from them shortly....

I was hoping it would work, too. The new one should handle anything I throw at it. For a little while. Hehe

P.S. Chugging the numbers --

A 3/8" line only has a 1psi drop for 9 feet of pipe using some very conservative values with a flowrate of 600bhp on E85 (89 US Gallons -- 337 lph)

I have the dual intank pumps from APS and have no issues at 600 rwhp on the stock feed line. They work great.
