new fuel pump looks different

I don't think any electrical pump will do well on waste oil. Or at least so I've heard.

I've heard all that as well........but why? The chemistry doesn't make sence to me. If the waste oil is acidic, caustic, alkaline or whatever: it will affect aluminum, steal, rubber, and so on the same reguardless if that material is found in your tank, your IP, injectors, Holley Red/Blue, Duralift or whatever. There is nothing special about the material found in an electric pump that isn't found in other areas of the IDI's fuel system......so if it's OK everywhere else..........why is it not OK in you fuel pump?

Without a better explaination, I'm not sold on the validity of that arguement.

My Holley red has been sucking down high WMO concentrations for 2 years. Never given me any problems.

Mostly having heard it elsewhere and from folks in the WVO community around here. However, I would think the electric motor in a comparatively small pump - as compared to a mechanical pump driven by a 8 cyl diesel - would not move heavier fuel as well.

Just me and my musings. It gets mighty cold up here in the winter and so far I can switch over to 100% wmo when coolant is 160 degrees. Maybe if we had more folks doing 100% wmo with electric pumps we'd have a good sample.

Not many folks running 100% wmo

Whats your % mix Mel?
