Fuel Transfer / Lift Pump SPKF2205.5-305 — Hand Priming Pump For Weichai WD615 & Heavy-Duty Diesel Supply Systems

A diesel engine can have perfect injectors and a healthy high-pressure pump-yet still suffer hard starts, hesitation, and "air-in-fuel" behavior-if the low-pressure supply side can't keep up. That's where the SPKF2205.5-305 fuel transfer pump (often called a hand fuel pump / lift pump / priming pump) earns its place: it helps move fuel from the tank to the filter/injection system and makes priming after filter service quick and clean. Instead of chasing intermittent issues, many workshops restore reliability by replacing this small but critical supply pump first.

In online parts channels, SPKF2205.5-305 is widely sold as a hand fuel pump for Weichai WD615 engine applications, commonly listed under OE-style part numbers such as 612600080343.\

 

 

SPKF2205.5-305 is typically described as a manual priming / hand fuel pump used on heavy-duty diesel platforms. Its job is to:

maintain steady fuel feed to the engine's fuel filter and injection supply circuit

allow fast manual priming after fuel filter replacement or fuel line opening

help reduce problems caused by air ingress and weak supply pressure

Many listings also present it together with the identifier DH0R00262 (commonly shown as a linked/cross reference in the same product family), which is exactly how technicians search during troubleshooting.

 

 

To capture real buyer intent (and reduce wrong orders), your product page should clearly include the number cluster that appears online:

SPKF2205.5-305 (also written as SP/KF2205.5-305)  

612600080343 (commonly listed for Weichai WD615 hand fuel pump)  

61200080343 (also seen in some listings for the same SP/KF2205.5-305 family) 

DH0R00262 (often shown alongside SP/KF2205.5-305 in supplier catalogs) 

Pro tip for your independent store: place "SPKF2205.5-305 + 612600080343 + DH0R00262" in the title and again in a "Cross Reference" block. That matches how customers search when the truck is down.

 

 

Online listings consistently position SP/KF2205.5-305 as a Weichai WD615 hand fuel pump / lift pump spare part. 
Because WD615 platforms appear across multiple truck/engine packages in different markets, the safest fitment rule is not "fits many trucks," but:

➡️ Match the pump number on your existing unit (SPKF2205.5-305 / 612600080343 / DH0R00262) before ordering.

That one sentence lowers returns and makes your store look professional.

 

 

Workshops and fleet buyers don't buy a lift pump for fun-they buy it to eliminate problems that waste time:

① Faster starts after service
After changing filters, a strong hand primer helps push fuel through the system quickly, reducing extended cranking.

② More stable idle & response
If the old pump leaks internally or can't hold feed, the engine can feel inconsistent-especially after sitting overnight.

③ Less downtime from "mystery air" issues
A worn priming/lift pump can contribute to air entering the supply line, causing intermittent drivability complaints.

④ Better maintenance workflow
Replacing the hand pump is often cheaper than repeated labor hours bleeding and re-bleeding the system.

 

 

Use clear, scannable trust signals:

Type: Hand Fuel Pump / Fuel Lift Pump / Priming Pump  

Engine focus: Weichai WD615 platform  

Replacement references: 612600080343 / 61200080343 / DH0R00262  

Add a small "⚠️ Fitment Note" box: Different suppliers may write the number with or without slashes/dots. Always match your old part label.

 

 

✔ Replace the fuel filter at the same time if service is due
✔ Inspect hoses/clamps for cracks (air leaks mimic pump failure)
✔ Prime until firm resistance, then check for seepage at joints
✔ After start, recheck connections-small leaks become big problems under vibration
