My 86 Ford diesel needs GP`s. One has the wire connector rusted off and think a couple others are inop.
I pull the lid and remove the filter, then stick my HF Heat Gun in the filter bucket for a few minutes.
She kicks right over. even when it was 20 deg the other morning.
I bought some GP`s, but can`t find them.
Nothing wrong with using WD-40, but I stay away from Ether.
Be sure to remove the filter, or it will catch fire.

Don`t ask......
