Initial Inspection/Disposal Criteria

  1. Visually inspect for evidence of use i.e., dust, oil, damage, loose or missing parts.
  2. Return to stock if there is no sign of use or damage and priming bulb can be squeezed easily.
  3. Refurbish as necessary if the assembly has been used, damaged or is incomplete.
  4. Dispose of the Fuel Line Assembly if it is not economically repairable.

Refurbishment procedures

A. Cleaning

  1. Remove dirt and oil using detergent and shop towels as necessary.
  2. Use pressure washer and degreaser to remove heavy deposits of oil and grease.

B. Repair

  1. Replace fuel hose if there are cuts, tears, burns or other defects.
  2. Tighten the quick disconnect fitting if loose.
  3. Replace cracked, torn or missing O-rings on quick disconnect fitting.
  4. Replace any ¼” fuel hose that is not gasoline, oil and ozone resistant. *Remove Goodyear INSTA-GRIP hose from service during the refurbishment process.
  5. Replace priming bulbs that are too stiff and cannot be squeezed easily.
  6. Replace fuel hose sections if assembly is not a minimum of 54” overall length.
  7. Replace worn brass swivel fittings that have been rounded over by wrenches.
  8. If assembly has an in-line fuel filter, replace the filter at each service.
  9. Secure hose connections using pinch type Ear Clamps (Oetiker® clamps).

C. Test for Performance

  1. Check function of priming bulb by squeezing; air should escape at hose-end opposite of quick disconnect fitting.
  2. Pressurize fuel line assembly to 8-10 psi and seal off, ensuring that there is no leak-down in pressure. If pressure will not hold, submerge in water or spray hose with soapy water to indicate source of air leak, repair as necessary and retest.
