When i replace my ipr o-rings on my 95' f-350 power stroke would it be better to replace all the o-rings in my fuel injector system, and if so how much will it cost?

 

What problem are you having? The IPR o-rings are cheap and easy compared to injector o-rings.

 

i think my ipr o-rings are going out because my truck will start fine and run fine but when the engine is hot and i kill it, it wont restart untill the engine is completely cooled off. but would it be a better idea to change all of the o-rings in the fuel injector system i know it will cost more than just the ipr o-rings and thats no problem.
