Fuel system difference

AltecBX · 04-28-2011, 03:25 AM

Good find from rem3 on the other site.

135i

1M

Could it be that the 1M has two inbound lines for more fuel on the N54...

Very interesting

What is that part # 2 on the 1M where the line gets double?

I believe is some kind of filter.

Are the intank pump part#s different?

Yup definitely a filter

Oddly enough, this second line only shows up when the Euro region is selected. The US region 1M N54T has the same line as that of the 135i.

Here's the intank pump for the Euro version vs US version :

So the 1M fuel system has a fuel return...Does this mean the filter they added in acts as a fuel pressure regulator? That would be the only way it could return fuel from the filter that makes any sense.

I thought there was already a fuel return? Maybe I'm wrong.

Looks like they both have a fuel return.
