[DIY] Created an inline fuel filter - Will that solve the injector issue?

Also NRW uses Aeromotive fuel filters in their kit. Aeromotive releases all their tech data about their products online and free. There is a reason the filter has to be a certain size. I’d trust Aeromotive over someone trying to make something just because it fits better.

In theory, by keeping it upstream you can have a lean-mixture issue, without having any low pressure fault. That's the issue itself.

I'm certain that NRW/Aeromotive has the best option.

That sensor does not detect lean issues, only low pressure

That's what I said.

I'm not really understanding what either of you are saying about the fuel pressure sensor.

.....

jvictormp on 10-1 said the sensor has been moved downstream (presumably after the filter, relative to flow), but you said upstream, I guess you mis-read his post?
If the sensor is after the fuel filter (downstream), and the filter were to get blocked, then the low pressure sensor will trigger a fault code surely?

Only observation I could make is: those "bolt/nut" style hose clamps (not the worm type, the other one).

You should inspect it often, because when I used it here, it tended to get loose overtime and begin dripping. Don't know why. It even disconnected the hose once . I ended up moving to PTFE AN Fittings. I could make a video of how to install the fitting in the hose if you want.

But I don't see a risk there because it's far from exhaust and you'll feel the smell before it gets severe.

The 'nut and bolt' clip is a proper fuel clip and will grip the hose evenly, it's more dubious to use jubilee clips (the worm drive ones), especially if they're wound to very near their minimum size.
What happens is that jubilee clips form an oval shape instead of a round shape when wound right in (or near to). This means the parts of the hose at the ends of the oval shape aren't clamped as tightly and could leak after a while.

With either type clip fitted to a new hose you are likely to need to tighten them again, say 6-12 months later if they weren't quite tightened enough in the 1st place. Especially in the 1st year the new rubber loses some of its 'springyness', hence what seemed tight enough, later isn't.
This is one reason why manufacturers like to use spring clips, as they keep a constant pressure on the hose as it shrinks and hardens.

Btw "feel the smell"? I think you meant smell the fuel , but either way, you don't want to find a leak by relying on smelling it, it'll be pretty bad by then!

After almost a year the inline e36 m3 filter has been tested.

Did one long trip to alps and 2 ~1h session track days in warm weather. And lots of backroad driving.
In total ~10k km.

Few months ago changed the filter and opened up the old one - no debris at all.
Few small black pits but probably came when opened the filter up.

For the clip experts, both clips were nice and tight No leaks at all

Also Inpa and Ista didnt give any codes.

That old fuel filter appears to be pristine , no surprise given the low mileage.
You could likely triple the mileage until the next change, and I'd bet it'd still be fine.

Have you got that inline filter in addition to the tank one?
