has anyone installed an inline fuel filter on a vehicle that has fuel injection? my 2006 sierra does not have an inline fuel filter and I would like to add one. Don't know what is involved, I'm guessing I need a tubing cutter and flare tool to do the hard line running up the frame rail. Are there any kits that make it easy to do this?
 
I'd assume you have a permenant in-tank filter and your inline filter won't catch anything, but I'm not too familiar with the GM's.
 
Very likely there is a filter already at the fuel pump in the tank. No need to add another one to the system. Just adds more points for leaks and would make the pump work harder to pass flow through a filter that likely won't see anything.

In addition, if the fuel injection is returnless, the filter is seeing way less flow than older systems with a fuel return.
 
One of my Toyotas has almost 300K on the factory filter, and has never shown a code related to fuel flow. It gets run pretty hard on the highway. It is a returnless system.
 
Yea, I wouldn't worry about this either......there should be a filter within the tank anyways.....either a "sock" type particle filter and/or a secondary filter within the tank....

And really.....I can't see our fuel being that dirty anyways....just make sure you grab fuel from well-traveled (busy) stations....sometimes the busy 7-11 station that gets gas daily...is better (less risk of contamination) than the top tier station that gets fuel loads weekly....
 
If you go to napa on a slow day they have fuel line repair kits that let you splice steel to nylon, nylon to nylon, steel to steel etc with compression fittings.

They also have nylon fix-it things with male and female ends.

If you pull a fuel filter for a 95 saturn vin 7, terrible example, it has a 5/16 inlet and outlet, a funny shape, but takes standard nipples, one male, one female. You can get stuff from the fix-it section to quick connect onto here. You'll also want room to flex to disconnect somehow.

Your truck likely takes at least 3/8 line. But the premise is the same; find a filter for an older version of your truck and check its diameter and rated pressure. Then open its box and find all the doodads you need to match up.

Naturally you need a cooperative parts guy.

pay me $200 then, I just had injectors cleaned and they said all were dirty and to change my fuel filter.

truck does not have a fuel filter anywhere between the tank and fuel injectors.
 
Your truck does have a fuel filter before the injectors; it is built into the fuel tank sending unit/fuel pump module. Adding an additional fuel filter isn't going to keep your injectors any cleaner and it would probably shorten the life of the fuel pump. If your mechanic told you; find a new tech.

I think you need to rethink this. Don't try to re-engineer something that GM spent millions already on. The new return-less fuel system don't need any additional filters.

If the injectors were dirty it was probably on the injected side and not the rail side.....deposits and such.Or else it was an upsell.
 
Try another brand of fuel perhaps? The filter is considered no maintenance/part of the fuel pump assembly.

By that logic, nobody should have re-engineered the gaskets that were used on GM V6 engines during the 1990s and early 2000s.
 
I to was disappointed that my truck has a non serviceable fuel filter.

I don't think adding a filter would be a bad idea at all. And yeah it will give the fuel rail cleaner fuel as long as it filters better than the stock one. I would be surprised if the stock ones were rated any better than 15 or 20 micron. Maybe worse

Won't flow enough? thats the same argument used against trans cooler filters.

One important difference: Fuel systems aren't failing en masse.

There is no evidence, not even circumstantial evidence, that additional filtration is needed for the fuel system.
 
Hoping the OP understands that injectors clogging and needing cleaning is not just a function of the "crud" in the fuel system. Deposits on an injector can form from the fuel itself, generally due to the high heat the fuel will experience at the injector that can leave residue etc...

So while I am not suggesting your mechanic found a nice way to lighten your wallet, I am suggesting the source of your injector clogging may very well have to do with the fuel you are buying. An additional fuel filter would do absolutely nothing to stop this type of problem. I am not a Top Tier advocate, but it is worth noting GM is a Top Tier fuel participant.

In addition, your truck does have a filter - built into the fuel pump assembly. To say there is nothing between the tank and engine is incorrect.

i understand that. my dilemma is i bought this truck used so i don't know it's history. it had a k&n col air kit, so that gives me the impression the previous owner did mess with it and would not surprise me if they used a bunch of fuel additives and cleaners which i thought turns that filter sock on the in-tank fuel pump black and degrades it. And all the spark plugs had what look like ash deposits on the insulator. Right now the tank is full on the truck, I really don't feel like draining and dropping the tank to check. And i don't want to install cleaned injectors if I have a problem in the tank.
I called the injector cleaner people and asked about their report which said all injectors were dirty and change my fuel filter. was told it's a default report and they classify it as normal dirty injectors, if they found real contamination then they would have advised cleaning the fuel cell or whatever. And they said i have to go with what i got, referring to all new vehicles now not having serviceable fuel filters, because "they" don't want us changing them because of gas evaporation and we all lose because of it.
however, in defiance i have AN adapters and hose and 16x1.5 fittings mail ordered so i will be able to easily add on a cheapo fuel filter on the intake.

So after everyone telling you not to do it you are going to anyway? Wow. Have fun with those injectors.
 
Lots of vehicles do not have serviceable filters. My Scion does not and my roomie's Neon does not. She does not take care of that thing at all, and has never had an injector problem in 200k miles.

Use a good fuel and the occasional quality injector cleaner like Techron and its about all you can and should do. I have had really mixed luck with those splice kits leaking. Sometimes parts just fail as well...it happens.
