What happens when the relief valve on a fuel pump fails?
What happens when the relief valve on a fuel pump fails?
Fuel pumps have a relief valve; if the relief valve is failing to open, more fuel than necessary will flow into the engine system. If your vehicle normally gets decent gas mileage and then suddenly becomes a gas hog, there could be an emergency under the hood.
How does the TCM differ from the Lycoming fuel servo?
The TCM System varies greatly from its Lycoming counterpart, the Bendix Fuel Servo. Perhaps most noticeable is the absence of a venturi to schedule fuel flow proportionate to air flow. The Bendix system regulates fuel flow by means of a delta pressure across an air diaphragm. Comparatively, the Continental System has no way to sense airflow.
What do they call Continuous flow fuel injection?
ontinental Motors calls it their “Continuous Flow Fuel Injection System.” Some technicians refer to it in less dignified terms, replete with colorful expletives. The proclivity of human nature has always been to focus on the negative.
How can I check if my fuel pump is working?
Before you check your fuel pump, find the fuse that corresponds to the pump and pull it out to see if it is broken or burned. If it looks fine, check the voltage at the pump itself to make sure the charge that’s leaving the fuse gets to the pump. If this looks alright, then perform a fuel pressure test.

What to do if your fuel pump fuse is blown?
Check in your owner’s manual for the location of the fuse box, then find the fuse that corresponds to the fuel pump. Pull it out and inspect it for signs of failure. If the fuse is blown, it will be broken or burned.
Where is the test point for a fuel pump?
Hook the pressure gauge to the fuel pump test fitting. Locate your fuel pump test point, which is usually near the fuel injectors, and locate the point at which the pump hooks up with the filter injector rail. There should be a separation joint or a test port, where the pressure gauge attaches.
