Fluctuating fuel pressure can be the result of the following: 1. A worn fuel pressure gauge; 2. A worn or broken O-ring on the inlet side fuel fitting; 3. A defective fuel selector valve (boost pump may labor); 4. An obstruction in the induction system (air intake); 5. A clogged or dirty fuel strainer; 6. Foreign material inside the fuel body (such as fuel cell sealant, thread sealant, or a drill shaving).
