Thanks guys!!

 

Welcome! What you probably have is a draw straw that was not installed right. The fix to this is empty the tank and put in a longer draw straw. When you do this, make sure that the tank is supported in its normal position, either by lifting the bed or removing the tank completely and placing it on sawhorses, then cutting the draw straw.

What you have is called the 1/4 tank issue.

 

How many gallons does it take to fill it at 1/2 tank? It could be that the fuel level sender in the tank is bad. If it is the level sender you will have to replace the whole tank module (Modified fuel module) or fix your current one. My gauge reads 1/2 tank when its empty too.

 

it usually takes 10-15 gallons depends on how close to half a tank i run it

Alright cool thanks for the help man another question ifyou know can you tell me how to tell what injectors I have? The truck has a good bit done but I didn't get much info on it from the previous owner and I'm just trying to figure it all out any help is appreciated

 

only true way to tell is to get the holes pinned.

you can tell if they are aftermarket performance or not by driving it without electonic power adders...

 

im guessing by electronic power adders you mean like a programmer if so i dont have one yet how can i tell if there aftermarket that way?

 

bone stock truck without a programmer or injectors can barely get out of it's own way...

truck with injectors is pretty peppy and tends to roll out a little smoke if you mash on the skinny pedal... (depending on size of the injectors) and boost will be higher than what a stock truck can do...

 

No programmer it will get up and go pretty quick and roll a pretty good cloud of black smoke has straight 4" exhaust to 6" stacks in the bed is there an easy way to hook up a boost gauge temporaraly to see how much boost I'm pushing without getting a boost bolt or drilling into the intake?
