FAQ

Q1: Will this valve fit my DENSO HP4 pump with part number 294000-0850?
Yes, the 294160-0110 is specifically designed as a replacement pressure limiting valve for the Ph4 (HP4) pump series, including model 294000-0850. Always verify your pump’s generation (Ph3 or Ph4) and ensure the physical connection matches before installation.

Q2: What are the symptoms of a failing pressure limiting valve?
Common signs include erratic engine idling, difficulty starting, reduced power under load, black smoke from exhaust, and fuel pressure warning lights on the dashboard. If you experience these issues, replacing the valve is a cost-effective first step before considering a full pump overhaul.

Q3: Is professional installation required?
While the valve is designed for direct bolt-on replacement, we strongly recommend installation by a qualified diesel technician. The fuel system operates at extremely high pressures (up to 2,500 bar), and improper installation can lead to system contamination or pressure loss. Always release system pressure and clean the mounting area thoroughly before replacement.
