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.

Are you sure there is no filter? Seems like every FI car has one.

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.

Please don't add another fuel filter to your car.

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.

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.
