Fuel transfer/polishing pump
Good point. I am painfully aware of how fast a Raycor clogs up
with dirty fuel Doug "Keith" wrote in message ... You need to look at depth filtration for polishing vs. surface filtration like the Racors. They will clog up very fast if you have dirty fuel. See the link I posted earlier, and take a look at depth filters like the GCF F-1 or Jr. "Doug Dotson" wrote in message ... I don't have a filter problem, I have a pump question.

No problem with that part. I want to be able to just transfer fuel or switch in a filter to polish the fuel while transferring. Since I can select the same tank for source and destination, I can polish fuel in place as well. The problem comes with the selection of a pump. I was looking at a Groco or Jabsco pump which seems good for transfer purposes, but way exceeds the flowrate of the filter when polishing. A Walbro fuel pump (which I have as a priming pump now) seems like a good fit for polishing (33 GPH) but will be slow when just transferring fuel. What happens when a 5.5 GPM pump (Jabsco) is pushing fuel through a filter rated at 60 GPH (RACOR 500)? Have built the system above which BTW, uses a lot of 1/2" bronze ball valves. You solve the filter problem in a straight forward fashion. Multiple filters (Larger than 500) in parallel to reach at least 60 GPH. I'd built in a safety margin and shoot for at least 75 GPH.
