This cuts down or “drops” the voltage downstream on the connector, and heat concentrates at the point where the voltages are unique; over the stage of greatest resistance.

If fuel procedure tension is minimal only underneath load, that doesn’t automatically suggest there’s one thing Mistaken with the fuel pump. Sure, a clogged filter might cause very low pressure and lower volume under load, but minimal voltage on the fuel pump connector will do the identical thing.

Any time a connector overheats, the plastic housing begins to warp and the condition tends to snowball; the contacts loosen or turn into corroded or contaminated, expanding resistance that generates far more heat and encourages corrosion that increases resistance more.
