The Wacker Neuson Cap Comp, Fuel Filler is a genuine OEM component designed for a wide range of Wacker Neuson walk-behind trowels, vibratory plates, trash pumps, and power screeds — including the CT36 and CT48 series trowels, PT3A centrifugal trash pumps, BPS 2550A vibratory plate, and HPG series truss screed power sections. As a direct OEM replacement, part is sourced from Wacker Neuson and built to the same standards as the original component fitted at the factory. Correct fuel cap fitment is critical across this range of equipment — a damaged or missing cap exposes the fuel system to contamination and presents a safety hazard on the jobsite.
Key Features
- Genuine OEM Fuel System Integrity — Manufactured by Wacker Neuson to seal and protect the fuel tank with the correct pressure venting and thread engagement specifications for these machines.
- Drop-In Thread Match — Threads directly onto the OEM fuel filler neck without modification, ensuring a secure, leak-free seal on every fitment model.
- Broad Cross-Model Compatibility — Fits CT36 and CT48 walk-behind trowels (including AGP, ADP, AGT, ADT, and AVP/AVT variable-speed variants), PT3A trash pumps, BPS 2550A vibratory plate, MPU 29A reversible plate, and HPG50/HPG100 truss screed power sections.
- Contamination Protection — A properly seated fuel filler cap keeps dirt, debris, and moisture out of the fuel tank, protecting injectors, carburetors, and fuel lines from premature wear.
- Fuel System Safety — A failed or missing fuel cap can allow fuel vapors to escape or fuel to spill during operation — replacing it promptly with the correct OEM part is a straightforward but important safety measure.
The fuel filler cap seals the opening of the fuel tank, preventing fuel from escaping during operation and stopping contaminants from entering the fuel supply. On compact construction equipment like trowels and pumps, even small amounts of dirt or water introduced through a damaged or loose cap can cause carburetor blockages, engine hesitation, or fuel system damage. When the cap is cracked, its seal is compromised, or its vent is blocked, you may notice fuel leaks, engine performance issues, or fuel starvation — replacing part 5100071567 promptly restores the integrity of the fuel system and keeps the machine running as intended.
