Reply to "Heat Soak and Flooding"

...Did I Not already suggest; the Throttle Shaft Bores were Worn?? BUT, They will NOT Leak While the Engine is Running, Because it is the Source of a Vacuum Leak!

One More Thing! I would Not mount that 'Steel Can' Fuel Filter right there, Behind and Between the Heads! Those Heads are 800-900 Degrees F! Perhaps even Higher! Anybody have a IR Thermometer, who can verify this? Shut the Engine off when Hot, right after a LONG Drive; and go back there and try to wrap Your hand around that Can Filter; You'll realize exactly what I mean! It IS a HEATSINK, and it delivers that heat into the Fuel. Think of how many Cubic Inches that can holds! Your Boiling the Gasoline!! I use to Have the Exact same Filter, I mounted it UP in the Decklid Opening, in the Cool Breeze! You should wonder why Racers use a 'Cool Can' to keep the Fuel Cold! To Me; it is Very Important WHERE You Install The Fuel Filter! If I wanted the Fuel Real Cold I would mount that Filter in a Bucket of ICE!! Right now I use -8 AeroQuip Hoses with a Much Smaller 40 Micron Filter, and that thing is Mounted, over the Fuel Tank, on the Pressure Side of Delivery!

I Don't 'Give a Crap' what might look Ugly!! I Want MY Pantera to look as if it Just Came Off the 'Battlefield', Victorious!!

You ARE correct to have the filter on the 'Pressure' side of the fuel delivery! To have put it Before the Pump, on the 'Suction Side' would, without a Doubt in My mind, cause 'Vapor Lock'!!
But You ARE causing that by Boiling the Fuel in that Steel Boiler You have rigged-up!

Thank-You!
