Information Zone Common reasons for a broken fuel transfer pump Share This Article: Copy to clipboard Copied Fuel transfer pumps are reliable, but sometimes they do stop working. and there are very common reasons for a broken fuel transfer pump. We have gathered a few quick solutions in this article to help troubleshoot any issues that may occur. Installation Issues Read the technical data! There may be something during installation that has been missed, so double check the set up instructions to ensure the pump has been installed properly. For example, check that the pump has been sited at the right height for efficient priming, tank venting requirements are being met, & electrical connections are as specified in the technical data. It is worth noting that a majority of our products have links to their respective technical documents which may also help with troubleshooting. The motor hums, but there is no fuel being pumped. Debris could be stuck within the rotor chamber. This could be due to contaminated fuel & no inlet strainer/filter being fitted to the inlet hose. A majority of our transfer pump kits come supplied with strainers. The pump is leaking. A leaking pump can be caused by too much pressure. The pump setup may not have adequate pressure relief; this can be a possible consequence of a hose being run over & flattened, kinked or fractured. Another possible cause could be leaving the pump on by-pass for a long time. This can melt & deform the shaft seal due to excess heat. The pump is transferring fuel, but very slowly. If there is a filter fitted to the pump, check that it is not blocked as this could cause fuel to be transferred slowly. At the same time, check for clogged tubes, hoses or nozzles; inspect them & clean as necessary. Possible air leaks; check that all hose joints have no cracks & are sealed properly. Check the tank is vented properly. If a filter or strainer isn’t fitted, check the vanes in the pump, as these may be worn or damaged & need replacing. Overheating fuel transfer pumps Check that the pump is not being run for longer than the recommended intervals (if applicable).Check for clogged inlet strainer, tubes, hoses & nozzles, then clean & clear debris as required. Routine maintenance for fault prevention Adhering to routine maintenance & inspection schedules can prevent operational issues developing; for example, cleaning inlet strainers at recommended intervals can help prevent some of the above faults occurring over time. Check the technical data for the specific fuel transfer pump model for its maintenance requirements. 24V Fuel Transfer Pumps – Hytek GB Ltd
