How does CP3 pump work?
In order to meter the fuel into the chambers, the CP3 has an internal metering/lift pump built right into it. This pump takes the fuel at supply pressure and boosts it to pressures between 80 and 180 PSI depending on what is required.
Do you have to time a CP3 pump?
The CP3 isn’t timed. It has about the same operating principle as your power steering pump.
How long should a CP3 pump last?
Forever as long as filtration is kept up. 01-02 are known to give out around 200K miles. If you need a regulator, just bite the bullet and put a CP3 in it.
How much HP can a stock CP3 handle?
On its own, the CP3 produces 24,000 to 26,000 psi of fuel pressure and can support a truck making approximately 550 horsepower at the wheels. When combined with a second (stock displacement) pump, the potential to make more than 1,000 horsepower is on the table. Such was the case with the LB7 Duramax shown here.
What are the types of injection pump?
Know Your Vehicle: The 4 Types Of Diesel Fuel Pumps
- Common rail fuel injection pump. An electronically controlled diesel fuel supply system, this pump was developed to meet the strict 21st century exhaust gas regulations.
- Distributor (rotary) fuel injection pump.
- In-line fuel injection pump.
- Distributor injection pump.
What’s the difference between demand and supply in a CP3 pump?
The commanded main fuel injection duration is the “demand,” while the CP3 pump is the “supply.” As the injector size gets bigger and/or the commanded fuel duration gets longer (more demand) the higher the supply is going to need to be. The factory CP3s are limited to what they can supply volume wise, mostly based on displacement and engine rpm.
Can a Bosch CP3 pump double the fuel?
This performance CP3 pumps can double the fuel of your stock CP3. Many are built from brand new Bosch pumps, and are capable of extreme horsepower and should only be used with high flow custom injectors. This performance CP3 pumps can double the fuel of your stock CP3.
When does Fleece performance cp3k lose fuel flow?
A: The Fleece Performance CP3K is a brand new Bosch pump that is modified to eliminate the factory fuel flow restriction that begins at 3000 rpm. The stock CP3 will start losing fuel flow and rail pressure after 3000 rpm.
Which is better Duramax CP3 or CP4 pump?
A: Unfortunately, since its introduction, the CP4 pump has proven to be less reliable and much less capable than the CP3 system used in previous Duramax platforms. While sufficient in a stock application, the CP4 will only support around 500 rwhp. At that point, it just can’t move the volume of fuel required to push power any further.
