Fuel System - MAULE Jetasen M-4 Maintenance Manual

AIR FILTER: (other than Brackett)
Visually inspect at each periodic maintenance. Follow cleaning instructions as printed
on air filter. Clean periodically as determined by environmental conditions encountered. Re-
place filter when cleaning no longer services unit.
BRACKETT AIR FILTER:
Service by replacement of element only when:
a) Every 12 months regardless of hours used,
b) or, every 100 hours use,
c) or, when operating in extremely dusty conditions, change frequently; use your
good judgment.
Special instructions for new element: Squeeze out all excess wettant in element prior to
installation. And DO NOT WASH OUT wettant as this will destroy some of the filter's effi-
ciency. Be sure safety pin is in place after installing.
CAUTION: When replacing Brackett Air Filter, insure compliance with AD# 96-09-06.
EXHAUST SYSTEM:
Check mufflers and tailpipes for cracks. Check attachments for security. Note that the
tailpipe clamps and the muffler-to header attachments should not be tightened to the point of
rigidity, but should be loose enough to be moved easily by hand.
Check the heater shell retaining screws for security and ensure that hot air hoses are
clamped tightly and are not worn or chafed.
Two (2) 21 gallon main fuel tanks, mounted in the inboard end of the wings, have front
and rear outlets.
The fuel lines running from these tanks terminate at the fuel selector valve on the left side
kick panel. The fuel selector valve has three or four positions: LEFT, RIGHT and OFF or
LEFT, RIGHT, BOTH and OFF. The fuel then runs though shut-off valve and through the
firewall to the fuel gascolator. Fuel runs from the gascolator to the carburetor.
If installed, two (2) auxiliary wing tip fuel tanks, eleven and one-half (11.5) gallon capaci-
ty, are mounted in the second from the outboard wing bay. They are fuel transfer tanks and
simply supply fuel to the main tank through a small vibrator pump.
