Overview
This Hipa kit is a replacement part, not a tool: four primer bulbs plus black and yellow fuel line, sized to fit the carburetor primer systems on a wide range of Echo, Husqvarna, and McCulloch chainsaws, trimmers, and blowers.
This listing is entirely about compatibility. Hipa cross-references its bulb and line kit against specific Echo chainsaw models (CS310, CS300, CS3000, CS340, CS370, CS400, CS420ES, CS450 and others), Echo blowers (PB760 and PB770 series) and trimmers (SRM400U, SRM410U), plus a long list of Husqvarna blowers, trimmers, and chainsaws, and several McCulloch chainsaw models. It replaces OEM part numbers 503936601, 530047721, 188-512, and 12318139130.
- 4 primer bulbs per pack
- 1 ft black fuel line, 2 ft yellow fuel line included
- Cross-references OEM parts 503936601, 530047721, 188-512, 12318139130
- Covers named Echo, Husqvarna, and McCulloch models
Who it's for
Owners doing their own small-engine repair on a chainsaw, trimmer, or blower that is hard to start or will not hold prime, on one of the specific Echo, Husqvarna, or McCulloch models listed. Not for anyone who has not confirmed their exact model number against the compatibility list first.
Strengths and trade-offs
Drawn from this product's published specifications.
- Four primer bulbs plus one foot of black and two feet of yellow fuel line included
- Covers a long list of named Echo, Husqvarna, and McCulloch models
- Replaces several OEM part numbers at once
- Fit depends on matching your exact model number, not just the brand
- No gaskets or check valve included in the kit
Performance notes
A primer bulb draws fuel from the tank into the carburetor before starting; once the bulb cracks or hardens with age it loses suction and the engine becomes hard to start or stalls. This kit replaces both the bulb and the fuel lines feeding it, usually the pair that fails together on an aging small engine.
