Fuel Starvation Under Load

When troubleshooting performance problems which are related to insufficient fuel delivery, the fuel pickup filter should not be overlooked as one possible source of restriction. Contaminants in fuels can restrict this in tank filter sufficiently to cause engine performance problems. In many cases, the engine will perform normally under light load conditions.

The in-line filter, although considered to be a "lifetime" filter, can also cause fuel starvation under load and hard starting if it becomes restricted.

The best method of diagnosing suspected fuel starvation which takes place under load conditions is road testing with a fuel pressure monitor safely installed on the vehicle.
