okay i had the fass put in yesterday well today i pulled in to my buddys apartment complex and the truck just dies and doesnt want to start back well i crack an injection line and it fires up. how would it be getting air in the lines now.

 

Double check the install. Make 100% sure its correct. Especially if you didn’t do it. We have install instructions on our web site to reference. What is your fuel pressure doing? Did you have an in-tank pump conversion done to your truck at the dealer? Did the shop try to run the FASS through the stock lift pump? (Had that happed before and the guy swore the instructions told him to do it....... ). Get me some more info on what is going on.

This happened to my truck when i did my FASS when i first installed it about 2.5 years ago. After that one hiccup, never had another issue. I think it was air pocket that broke free somewhere in the lines or pump that just broke prime (using the stock filter houseing?). It got in there when the lines were open for the FASS install.

 

no the stock fuel filter housing and pump are out of the system.
i took the truck back to them and they looked it over and said the pump didnt seem to be pumping right so they have ordered another system and are goin to install the new pump and filters. i hope this fixes the problem i plan on taking a 3hr trip to ride four wheelers this weekend and i need my truck to pull everything thats goin.

 

What shop was it? Have them call me.

 

thoroughbred diesel performance out of winchester, ky phone number is 859 737 4966.

 

Ok...ive talked to them before.....ill give them a call....

 

thanks let me know what they say. but they told me they should have me a new pump tomorrow at bout 2 and have the new pump in the truck in an hr. so hopefully its all good after that and i can get goin on my trip

 

You dont have the intank pump in your truck? Never went to the dealer and got that done?

 

no never had that done.

 

Its sounding like a restriction issue. BUT he couldnt give me any FP readings....this will tell alot. They are going to try the "5 Gallon Bucket Test" to confirm this. Something simple is going on here...just need to find it.

 

so you dont think its the pump, just some kind of restriction. im wondering why it seems like its pulling air cause its acting like the couple times i had air in the system. but its mainly seeming to go on when i get on it above 2000rpm.

 

A fuel pressure reading would tell me a lot if we can get one........

 

ok. they said they would have to put like a T in the line to get a reading.

 

whats the 5 gallon bucket test.
