Inline Fuel Filter question

[MTF]

I disagree, @Jeremy Hadowanetz

1. With modern unleaded fuel with additives and detergents now a days,
carbon build up like your saying are things of the past.

2. And there is no problem adding these proven cleaners to any Supercharged and Turbo vehicles.
Now, could you over do it and put too much in, yes. It will run like crap a little. Just ask me, LOL
Just read the directions!!!

3. The Enzyme additive is strictly designed to eat up ethanol and water in the tank!!!

Certainly, no need to drop the tank!

1. This is probably true I had a 2011 ecoboost f150 that I pulled the heads on to check for sludge at around 55k and they were surprisingly clean... pretty much gathered all the fear of di was overblown at that point

3. I personally would drop the tank in this situation from time to time (OP has rust/scale in his field fuel tank) but i have other vehicles and take stuff apart for no reason pretty regularly

Being a chem E in the organics field I can say, 1. If you don't use them regularly or after a rebuild don't bother, breaking a large chunk of carbon off into a cylinder is not great. 2. In forced induction engines octane and air/fuel is key so the additional additive could be doing more harm than good.

36 gallon tank = 4608 oz
1 fuel treatment = 11 oz, 2 treatments required for 36 gallons
total possible dilution 0.478% this means even if this was an unburnable mixture you would see an AFR change so small most PCM's wouldnt even make a correction, full power lambda of .73 under boost would need to become .726 lambda.

All of the cleaners are petroleum distilates, usually some blend of xylene, naptha, toluene and alcohols, all of which have a higher octane than pump gas, are used as octane boosters, and contain between 62% and 103% of the energy density of gasoline. So how is this 0.478% of whatever that blends energy difference is going to cause damage via AFR? Lets say they used 4x the recomended volume, hitting 2%, your still seeing a negligable energy and octane change, and oh by the way the computer can easily compensate for this by pulling spark.

I might not be a chem E, but the math says your instructors failed you.

While all of this is/may be true (up to and including my professors proficiency) you're saying a lot without saying anything here. The good done by the cleaning agent is going to be almost nonexistent for the OPs needs, so any loss of octane/timing is a negative without an equal gain.

Saying a lot without saying anything? I am pretty sure I showed that there is gain in octane, not loss. You sure your degree wasn't in politics?

Can you quantify the cleaning agent not doing anything? What does it not do, any evidence that these blends don't function for their intended purpose? If your going to act like an expert lets see that expert testimony.

He said a lot relevant things. Are you sure you're a ChemE? lol

I'm not saying the agents are without merit, I'm saying they don't apply in this specific case(possibly 8+ year engine, high mileage, no history of cleaning the fuel system). The OP states he has a risk of rust in the tank, the cleaning agent isn't doing anything to remedy this. Being that there is no positive pertaining to the rust/particulate issue why take even a slight hit on timing? I don't believe any risks are great but dropping the tank is the proper fix here in my opinion.

I can be wrong and your data set isn't being questioned but I personally would take care of this issue mechanically.

I agree, if there is rust in the tank it needs to be dropped and replaced. How in the world rust gets into a tank that is made of plastic and has no ferrous components in it is beyond me.

Also, I don't believe all the fuel system cleaners are good, or work equally well. The way I look at it is this: Somewhere there is some guy that has a bunch of huge vats of various petroleum distillates, trying to figure out how to optimize his profit on selling them. Some are really useful and valuable, some aren't. So he mixes a little a, some b, some c put a label on it and calls it fuel system cleaner, or wood finish, or ant killer, or dog food and sells it.

On average a consumer doesn't really pay that much attention to what they are getting. They see a bright pretty package and a price tag they like so they add the goo to their fuel system and get a nice placebo effect out of it, they feel good about taking care of their car and the machine of commerce keeps on spinning. When was the last time you dissected an MSDS to figure out what the fluid was you were putting in your car?

There is also some real benefit of running a quality cleaner when needed. Injectors are expensive and old fuel or sitting for weeks on end regularly is really hard on them. If you drive your vehicle regularly, use and refresh the fuel, and buy from quality stations you may never have a need. Modern fuels are light, they contain a number of compounds that just don't age very well, use them up quick or stabilize them. Best thing you can do is drive your truck.

Apologise if this has been covered already, have spent the last hour search posts to see if there were any answers to this question and came up with nothing.

that being said, I’m wanting to put an inline fuel filter on my Gen1 Roush Raptor. I know the truck has a fuel filter that is said to last it’s life time that is in the fuel tank but as I use my own fuel bowsers and I am at a higher risk of getting rust particles etc from my tank I am wanting to have a little more peace of mind.

Has any one done this mod and if so does it interfere with the fuel flow required for the Roush SC or the computers fuel sensors?

I've been thinking and researching for a little while about adding an inline fuel filter as well. Was wondering if you have found anything yet other than people arguing about fuel treatments.

hey mate, nah I just put it into the “ignore” section of my brain, haven’t read anything on here yet about injectors going on the Gen1s (also didn’t go looking for any posts either haha) so thought they must be all good with the duel tank filter.

I have stuck to fuelling the rig up with premium 93-98 as the tune I got from JDM was for that. Getting better mileage so haven’t needed to fill the truck at home with my own petrol bowser so no real need anymore for an in-line filter I guess.

if you do find anything I would probably still be interested just for extra security
