- Aftermarket fuel pump: Replaces OEM part number 861155A3 or 861155A2
- For low pressure use. The small outlet end is threaded for low pressure applications only
- This is a low pressure pump that fits carburated engines with a single fuel pump or some fuel injected engines that use a low pressure and a high pressure pump system. This is the low pressure pump that is threaded on the small outlet end. The high pressure pump looks similar but is not threaded on the small outlet end. The high pressure pump is enclosed in the 'cool fuel' assembly and this will not fit work in that asembly. Low pressure pumps are not in any assembly.
