Default Fuel Pump Pre-filter options
Went out to the track today but didn't get to run. I'm pretty sure I got some bad/dirty fuel and that clogged the pre-filter and has damaged my fuel pump. I have ordered a new pump but have a question about the pre-filter.

Is there any reason I can't use those $10 glass filters from Mr. Gasket that I can get at O'Reilly as a pre-filter? They say "Not for use with EFI" but I'm thinking that means "post-pump" due to the higher pressure. In a pre-filter setting there is no pressure, only a small amount of vacuum that will vary depending on how dirty the filter actually is.

The other option is the $70 Holley reusable billet filter. It would be nice to use the glass one to visually check to see if it needs cleaning.
