iam on my second set of injectors the best price i found was e.t.r diesel ... i was driving & #4 fuel line blew sprayin diesel everywhere when i shut the truck off it wouldent start.. i had the line replaced but had to use quick start to get it goin ... drove it to the dealer n they told me #4 injector was gone & the rest of them were not givin back the right retuns ... they are still under warrenty so i sent them back still waitin on my new ones ... but the killer is i have The Fass 150 but when the sent it, it came with a 16 micron filter ... stupid me not knowing i got the part # & kept buyin the same filter ( The 2 Micron Filter to get with the Fass is Fleetgaurd HF6604) but i wasent aware at the time they run about 65 bux the other filter i was buyin for it was $17 just a little drifference ... iam in the process now of adding 4 fuel filters & 3 fuel water sep. over kill ... nahhhhh $10 a filter seems better than injectors & the down time of ur truck

 

How does one verify if the injectors are working as they should be or if they are making the truck get poor MPG?

I have 145K miles on the truck, just curious to verify that the stock injectors are working as they should.

Thanks

U'll know if there not working right, the truck will act funny then it did before and it probley won't start without either. Could be a bad miss in the motor when driving it too.
