^^ This one.
Rationale ==> Think of all the entry fees, testing time, and frustration you've had. What's that time and resource worth? Wouldn't it be more fun to just race the thing as intended?

Any reason you can't retrofit an OE unit like the 2002 camaro unit shown above?

Only unmodified OE fuel tanks or legit fuel cells (with no external surge) allowed. Lemons racers are in the bad overlap of the ((Creative // Unskilled)) Venn diagram.
One other option if I really don't want to just spring for the FCST unit, what about just dual lift pumps on opposite sides, with check valves and a Y-connector to the HPFP? Probably wouldn't drain to the last drop, but does give a standalone pick up on each side.
This ATL surge tank might work?
Just got off the phone with Holley tech support.
Their take is that the fuel cell foam is the issue: it's both pushing down on and wicking fuel away from the mat. The recommendation was to remove the foam completely.
I'm probably not going to do that, but I could see cutting one or more channels out of the bottom of the foam, allowing for an uncompressed path for the fuel to get back to the outlet fitting.
Interesting, good to know and try. I've used the foam to hold the hydramat in place, maybe another plan is needed there.
A friend of mine had this issue on his truck and the first thing he looked at was tank positioning. Its possible that because the cell is tilted down in the front, fuel might be pooling away from the Hydramat during acceleration. Even if it covers 85% of the cell, if fuel is pooling in that 15% over and over again, that could cause some issue. Not saying its the whole reason but it could play a part.
