About CP4 failures
When a CP4 pump fails it can send metal debris through the whole high pressure system. Replacing only the pump is rarely enough: rails, lines and injectors must be inspected or replaced, and the fuel system flushed.
Before you install
- Inspect the fuel for water or metal particles and replace both filters.
- Check lift pump pressure. Low supply pressure shortens pump life.
- Prime the system fully before the first start.
