Is your inline fuel filter plugged? Sometimes it's hard to tell, especially when methanol may have been left in the lines between races.
Test your fuel filters regularly by modifying the cap of a 5-gallon jerry can to accept bulkhead fittings for air from your engine leakdown tester and fuel to another jug.
Put some fuel in the jerry can and pressurize it with inlet air from the leakdown tester at the same pressure as your fuel pump runs (50-90 psi). With a new and unused fuel filter in the outlet hose record the backpressure as fuel flows into the second jug.
Replace the new filter with a used one and again measure the back pressure. If it is more than 10 percent higher this filter may be plugged.
