Identify the fitted housing, read the element code and send the right details for a replacement enquiry.
QUICK MATCH · RACOR MA HOUSINGS
Find the element family
Use the full model on the housing label and the micron rating already specified for your fuel system.
For other housings or unreadable labels, send photographs of the housing and old element.
Start with the fitted housing
For a replacement element, the Racor housing model is more useful than the vessel or engine brand alone. Photograph the complete housing designation and the code on the existing element or its packaging. Include any suffixes that are visible.
The quick chart below covers the marine MA applications listed in Parker’s guide. It identifies element families; it does not select a complete fuel filtration system for an engine. Other Racor ranges need their own model check.

Why the replacement code may look different
Parker published updated 2020 and 2040 element codes. These cross-references help when the old box and a proposed replacement use different numbers.

Confirm the required micron rating
Use the rating specified for the installed fuel system. Engine brand alone does not establish which element or micron rating is required. A change from the existing rating should be checked against the equipment requirements rather than treated as a routine equivalent.
For an unidentified filter, send clear photographs instead of choosing the closest-looking part. If several engines or generators use different housings, label each set of photographs so the quantities can be matched correctly.
