In-tank vs In-line: In-tank pumps are preferred over in-line pumps for multiple reasons. Most importantly, in-tank pumps do not experience the priming issues that can sometimes occur with in-line pumps. In-tank pumps can be found on practically all late model cars due to their simplicity and effectiveness, and as stated above, are required for returnless-style fuel systems.

2. With the sending unit out, remove the old fuel pump and replace with your new pump. Two 40-60mm hose clamps are included with the FAST™ in-tank fuel kits to order to mount the pump. A sock-type pre-filter is also provided and should be connected to the bottom of the pump.
Page 12
To assemble hoses, use the following procedure. 6. Cut hose to the desired length using a fine tooth saw or cut-off wheel. Be sure to clean the cut edges of any loose material. 7. Lube the barbed end of the fitting with a light oil such as WD-40. 8.

RPM Module ® EZ-EFI is an advanced fuel injection system. Engine speed is one of the fundamental elements of its fueling calculations. When not controlling ignition timing, it relies on the vehicle’s existing ignition system for a steady, reliable RPM signal. An inconsistent or noisy RPM signal can appear to the ECU as erratic engine speed.

After starting the engine, use a timing light to verify that the timing is correct. The ECU will lock the timing to 20° of advance during this test. That is what the timing light should show. If it doesn’t, use the Plus or Minus buttons to fine tune the ignition setup until the timing light does show 20°...

will be sent to the selected textbox. (For E85 applications, you may only need to enter two digits. For example, enter “92” for a 9.2 air/fuel ratio.) The ECU is constantly working to keep the air/fuel ratio at the current target air/fuel ratio. It is preloaded with typical targets.
Page 50
Just as the Cruise Air/Fuel target can be adjusted for fuel economy, the WOT Air/Fuel target can be adjusted for maximum power. It is quite possible that the engine can make more power at an air/fuel ratio that is leaner (higher number) than the preloaded WOT Air/Fuel target. Or it might prefer a richer (lower number) air/fuel ratio.

more or less cranking fuel, that adjustment can be made here. SETTING EFFECT Positive More cranking fuel Negative Less cranking fuel Cold Start After the engine has started, the ECU’s closed-loop fuel control will begin altering fueling to maintain the target air/fuel ratio. When the engine is cold, the target air/fuel ratio is adjusted to a richer (lower number) value.

Vacuum Advance An RPM-based timing curve is set on the Timing Setup screen. It is similar to mechanical advance on a traditional distributor. The Vacuum Advance feature is similar to a vacuum canister on a traditional distributor. It can add ignition advance based on manifold vacuum as read by the MAP sensor. This feature is disabled when the throttle is closed to mimic a traditional ported vacuum arrangement.

wideband oxygen sensor provides very accurate feedback to the ECU so it knows if more or less fuel is needed to achieve the desired air/fuel ratio. Adjusting the fueling based on feedback from an oxygen sensor is commonly referred to as “closed-loop” fuel control. Closed-loop fuel control is a very powerful feature.
Page 62
Learning does not begin until the engine is warmed up. Coolant temperature must be above 140° F for learning to begin. There are various qualifying conditions that must be satisfied for learning to take place. This prevents the ECU from learning from inappropriate feedback. Many of the learning qualifiers have to do with making sure the engine is in a steady state condition –...

0, the TPS should be re-calibrated. This can be done by selecting TPS Calibration from the Advanced menu. It is normal for fuel pressure to rise and fall with varying engine load. Fuel pressure will be lower at idle and in normal driving when there is more vacuum in the intake manifold. Fuel pressure will rise as the engine approaches wide open throttle.
Page 64
On-Board Diagnostics ® The EZ-EFI system includes a robust self-diagnostics feature. The ECU constantly monitors various inputs and outputs for any deviations from normal operation. If any are detected, the blue CRANK/DIAG LED on the ECU flashes rapidly as a warning that there is a problem. (That LED comes on solid when the ECU detects an RPM input.
