E85 in Returnless System Question

Is it true no manufacturer sells an e85 compatible fuel pump for returnless systems? I am being told the e85 compatible pumps are sold only for the return type systems. I was also told I can "try it" however the pumps may last 3 months or 3 years. This sounds like a company trying to cover themselves in the event of a failure would you agree? I don't know much about e85 but I find this hard to believe. Anyone know about this?

I haven't done any homework on the subject, but I highly doubt that's the case. Think about all of the OEM flex fuel vehicles out there that aren't return systems.

Who was it that told you that? I would contact the guys over at Lethal Performance, they seem to know their fuel systems.

This is exactly what I was thinking because it is a logical way to think. I would love to air out the company that told me this but I don't want to stir anything up. I don't believe they have any affiliation with AFM thankfully. I will definitely contact Lethal Perf. I should have done that to begin with.

@SilverGTvert, what type of fuel filter are you using? I am using an element type (reusable) Aeromotive billet type filter. Will this work with the E85? I am not sure if the alcohol content will affect the material in the element.

No issue using the OEM fuel filter. Check with Aeromotivr on E85 compatibility of your specific filter.
