7875 + 5.9 + E85 + Megasquirt

That’s going to come out great! How much fuel does the new tank hold?
This is the Rhodes 17 gallon I posted previously. They have a 25 gallon model that is a similar foot print but it’s 10” deep and I thought it would hang too low. This one is 7” deep and a little more stealthy. It has a sump but the really cool feature is that they sale a bolt in in-tank Fi module that will support up to 2x 450lph pumps. Room for growth.

Haven’t done anything yet to replace the trunk floor. I’m thinking either flat sheet metal, welded in or maybe a removable aluminum sheet secured with Dzuz screws.
