C230 Sport Coup

Looks like my fuel pump has bit the dust, It's looking like it would be a good idea to do the filter as well.
I checked lots of threads with people replacing the pump and then it not working, but not mentioning what the fix was.
Those who have performed this, can you chime in the best practices for doing both sides at once?
And for those who had issues get the pump to work once installed, what did you do to fix it?
Thanks. Here's the VIN in case someone wants it.

Explain what the problem is that you think it is the pump.

Suddenly would not start.
No codes.
There's no fuel pressure, the
fuse is good. Relay is good, swapped with horn relay,
Mileage just over 200K which is when my C Coupe's pump failed.

Maj. Dundee

It's a fuel filter problem which has a life of around 155,000 miles.

Me lady decided to not have me do the work,
just as glad not to,
New pump, filter/sending unit, and new sensor, plus
oil change, and some repair to fix a
power steering pump leak, the reservoir or something and seals.
$1500 smackers later....back on the road.

You did get smacked. The entire set-up is about $500 but $1k for labor is criminal.
