LIDSCURA Fuel Pump and Fuel Filter Kit for Onan/MicroLite QG4000 4 kW — Direct-Fit Replacement with Hose & Clamps

LIDSCURA 149-2311 fuel pump and 149-2457 fuel filter kit replaces worn components in Onan/Microlite QG 3600–4000 series RV generators to restore reliable fuel delivery.

When an RV generator stumbles, stalls, or runs rough after long use, the usual suspects are an aging fuel pump or a clogged filter. This LIDSCURA replacement kit bundles a direct-fit fuel pump and compatible fuel filter with hose and clamps so you can complete the job in one service visit. The parts are engineered as replacements for common Onan and Camp Power/Microlite QG series part numbers, making it simple to match to your 4 kW and similar generator models.

How will this kit improve my generator's performance?

Replacing a tired fuel pump and a blocked filter restores steady fuel pressure and clean flow to the carburetor and injector. That smooths idling, prevents sputtering under load, and reduces the chance of hard starting. The kit replaces factory part numbers with equivalent components designed to match original specs.

• Restores consistent fuel pressure for stable engine operation
• Removes debris and varnish that restricts flow
• Prevents fuel starvation during startup and heavy load

Which generator models and part numbers does this replace?

This LIDSCURA assembly is intended for Onan MicroQuiet and MicroLite (QG) family units and compatible Camp Power/Microlite models. It replaces multiple factory part numbers so you can confidently match the kit to older generators needing service. Always verify compatibility against your generator's model plate and manual before purchase.

• Designed for Onan MicroQuiet 3600, 4000 and QG4000 (4 kW) models
• Compatible with Camp Power KYD MicroLite, KY MicroQuiet and QG series
• Replaces fuel pump part numbers: E11007, A029F889, 149-2311, 149-2311-01, 149231101

What comes in the package and how easy is installation?

The kit includes everything needed for a standard pump-and-filter replacement so you don’t have to source small parts separately. The components are arranged to simplify installation, with hose and clamps sized for direct connection to original fittings. Follow basic safety practices—work with a cool engine, and avoid open flames—then swap the old parts for the new ones, reconnecting fuel lines and clamps securely.

• Included: fuel pump, fuel filter, fuel hose, and four hose clamps
• Hose and clamps match common generator fittings for a tidy install
• Designed for bolt-on or bracket mount depending on your unit’s layout

How long will replacement parts last and what maintenance helps prolong life?

Longevity depends on fuel quality, usage hours, and storage conditions; using clean, stabilized fuel reduces contamination that clogs filters. Regularly inspect fuel lines for cracks and replace the filter at intervals suggested by your service manual. If you store the RV for extended periods, drain fuel or add stabilizer to limit varnish buildup.

• Use fresh, ethanol-minimized fuel when possible
• Replace filter as part of routine maintenance or when service symptoms appear
• Inspect hose clamps and connections during seasonal checks

Who is this for: This LIDSCURA pump-and-filter kit is aimed at RV owners, mobile technicians, and fleet managers maintaining Onan MicroQuiet/MicroLite QG series generators who need a reliable, ready-to-install replacement. It's especially useful for anyone troubleshooting rough running, sputtering, or inconsistent starting on 3600–4000 series units who wants a complete parts set to finish the job in one visit.
