High Pressure Fuel filter looks........

........the same as the low pressure fuel filter ! Not that I know they differed !!!

I've just installed a water / fuel separator (thanks for your advise in an earlier post) and at the same time decided to change the two fuel filters under the hood of my Mercury 115 4 stroke. They both look identical so I went online and purchased two OEM filters (12.99 each from Pace Marine - speedy service by the way) and fitted both. 5 minute job, happy days.

I then found myself flicking through the maintenance manual for the engine only to read that one of the filters is detailed as "High Pressure " and should only be changed by an authorised dealer". What.....!!!

Question - do the filters differ despite looking identical and why the need for specialist assistance when both filters come with click and go attachments for ease of use.

Is it because the fuel is pressurized in one and no the other and a such needs to be bled before change - help and advise sought in case I'm about to regret attempting the job myself - thanks.

The high pressure filter is the one to the right, just aft of it is a release valve (tyre valve) which I've bled.
