RE516335 Fuel Rail Pressure Relief Valve Sensor Replacement for 5100M 7520 4045 6068 Engine Tractor

RE516335 Fuel Rail Pressure Relief Valve Sensor for 5100M 7520 4045 6068

RE516335 is a fuel rail pressure relief valve with sensor, supplied by an OEM supporting factory that builds fuel system valves, sensors and solenoid components for construction and agricultural machinery. It opens at the specified pressure to release excess fuel back to the tank and protects the rail from over-pressure, while sending the signal the control unit expects — fitting the original port and the original plug with no adapter, no rewiring and no modification.

Product Overview

• Part number: RE516335
• Product type: fuel rail pressure relief valve (pressure limiting valve) with sensor
• Engine: 4045 and 6068 diesel engine
• Application: tractor 5100M and 7520, genset powered by 4045 / 6068 engines
• Supply type: OEM supporting factory supply, original tooling
• Condition: brand new unit, never installed on a machine

Technical Specifications

Quality and Material Advantages

• High-grade sealing, diesel and heat resistant. Internal seals use high-quality oil seal material that resists diesel, pressure peaks and continuous high temperature on the rail, so the valve does not seep, stick or leak after installation.
• Pressure setting matched to specification. Every valve is set and checked against the original opening pressure, so the rail is protected without the low-pressure cracking or early opening that causes hard starting and power loss.
• High hardness, wear resistant body. The metal housing, spring seat and thread are hardened to resist vibration, pressure cycling and repeated assembly without stripping or corroding.
• Built for high-intensity working conditions. Specified for mining, quarry, earthmoving, heavy agriculture and continuous genset duty where the fuel system works long shifts under load.
• Tested before shipment. Opening pressure, sealing and signal output checked unit by unit, then packed in anti-static bag and foam-lined export carton.

Application

Fits tractor 5100M and 7520 and gensets driven by 4045 or 6068 diesel engines that use part number RE516335. Also used on other machinery running the same engine family and valve thread. Commonly replaced when the rail pressure reads abnormal, the engine derates or loses power under load, the engine is hard to start hot, or a fuel system pressure fault code is stored.

Common Failure Symptoms This Valve Fixes

• Fuel rail pressure reading low, unstable or dropping under load
• Engine derating, loss of power or sudden shutdown
• Hard starting, long cranking or rough running when hot
• Fuel leaking from the relief valve or a pressure fault code in the control unit

FAQ

Q1: Is this the same as the original factory part?
A: This is a replacement fuel rail pressure relief valve produced by an OEM supporting factory that supplies components to machinery makers. It is built to the original specification and fits the same port and plug as RE516335.

Q2: How do I confirm it fits my machine?
A: The unit is listed for tractor 5100M and 7520 and for 4045 / 6068 engine gensets. If your model differs, send the model, serial number and a photo of the old valve including the plug and thread — we confirm within 24 hours.

Q3: What is the price?
A: Price is negotiable and depends on quantity, packaging and shipping terms. Send your quantity and destination port and we will quote the best FOB or CIF price the same working day.

Q4: What is the minimum order quantity?
A: 1 piece is acceptable for trial orders, so workshops can test quality before bulk purchasing. Unit price drops from 50 pieces upward.

Q5: Does the valve come with the sensor built in?
A: Yes, this is the complete assembly with the pressure sensor, ready to bolt on and plug in. No separate sensor purchase is needed.

Q6: Is the part new or refurbished?
A: It is a brand new unit, never installed. Each unit is individually bagged and boxed before shipment.

Q7: How long is delivery and how do you pack?
A: 7-15 days for stock items and 20-30 days for production orders. Units go into anti-static bags and foam, then export-grade cartons, palletised for bulk orders.

Q8: What payment terms do you accept and how do I start an order?
A: T/T, L/C, Western Union and D/P. Send part number, quantity and delivery address, we confirm price and lead time, then issue a proforma invoice. Goods are shipped once the deposit is received.
