something to think about, if the 98 works on the 95, why wouldn't the 95 work on the 98. question is why would you swap the pumps unless something is wrong with it?
The seller swaped out his 95 for the 98 because of the higher factory set power output.

Grinding your fuel plate to a different profile, installing an aftermarket fuel plate or removing the plate altogether will far exceed the "factory set" HP rating. Of course, its not quite that simple - you need to do some supporting mods and some tuning may be involved, but you get the general idea.

i changed my pump myself and that was a total PITA! i don't see why anyone would go through that (unless building a racing truck) for the extra hp? i'd have to agree with evil when i could throw a plate in and tune the afc much easier get noticeable differences. just trying to make sure your not getting shafted by the seller trying to pawn off a busted pump on ya. i'd hate to see anyone buy a not running truck and the parts that were given to them to make it a running truck be in none working condition, cause these pumps aren't cheap....

im not a complete expert on them. but im pretty sure they came on bigger trucks. they basically made it able to have more fuel and timing but yet it can retard it for easy starting. but correct me if im wrong. bc i have a few junkyards for big trucks around me that have them pumps on them. i forget the name but i wana say its a PE7100?? not sure. also if you need a pump why dont u go to the truck boneyard a get a 14mm pump off a dump truck or rig with a 5.9?

I never heard of those. Learn something new every day. I guess I should redo my statement then: P7100's, as installed on dodge trucks, were never electronic.
