WARNUNG
Tip
Fuel pressure regulators have very precise toleranc-
es and are generally reliable. Pressure fluctuations
are not caused by the pressure regulator, they have
to be searched in other areas (filter clogged, pulsation
of lines, kinks in the hoses, etc.) of the fuel system,
before troubleshooting the pressure regulator.

WARNUNG
Tip
Vapor bubbles in the return line must be efficiently
vented out of the fuel system to atmosphere. Ade-
quate fuel tank venting system design is imperative.
Large vent lines with (most) direct routing avoiding
low points are desired.

WARNUNG
Tip
A header tank design that efficiently jets vapour bub-
bles back to the fuel tanks and atmosphere without
possibility of re-entry into the suction line, is critical.

WARNUNG
Tip
Non drainable low points in feed, return and vent lines
must be avoided.
Any low points must allow for drainage of water and
other contaminants.

WARNING
At the low points, accumulations of water can freeze
and cut off the flow.
