OE 31090-3J500 — Filter Fuel Pump for Hyundai

Build-year coverage is listed row by row in the Applications table above. Where several generations share one number, the newer rows usually carry a revised suffix — compare the last four characters before buying, since a suffix change often means a different connector or bracket.

Four variables explain most of the spread: material grade, whether the goods are new production or clearance stock, packing format, and whether the quote is ex-works or landed. Ask for the material certificate alongside the price — that is what makes a comparison like-for-like.

Watch for noise on cold start, vibration under load, warning lights, fluid seepage or uneven operation. Once any of those appears the filter fuel pump should be inspected, and reference 31090-3J500 replaced if it measures outside specification.

A supersession happens when the maker revises a filter fuel pump and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 31090-3J500 we list the current reference; ask our desk for written confirmation before a large order.

Export packing is a neutral carton with inner protection; custom labels, barcodes and box specifications are available for volume orders. Shipments move FOB Guangzhou or Shenzhen, with CIF and DDP terms negotiable.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a filter fuel pump the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.
