If carbureted check float levels, or rear jets getting uncovered. If EFI and stock tank, possibly fuel pickup in tank getting uncovered?
yep is 1050 Dominator ! when i have checked bowl level and was ok but after pass the rear bowl was low .. but after 5 minute when come back at my box was ok ... very strange ....Fuel Pump is Aeromotive A2000 all 10AN Fuel Line ... im also think the problem is possible on furl line issue
