How to check fuel pump pressure

My Boxster Idel's pretty rough would like to check fuel pressure  02'  2.7  Boxster

I was getting a “blowing over a coke bottle” sound from my 2000 Boxster S. I changed the fuel filler vent valve and gas cap but the sound is still there. Squeezing a blue “check valve” makes it go away. Thoughts on how to fix?

I was getting a "blowing over soda bottle" sound from my Boxster S.  I changed the fuel filler vent valve and gas cap but the sound is still there.  I noticed that when I squeeze what looks like a blue "check valve" on the line the noise stops.  I don't know how to change the check valve or why that would cause the sound.  Anyone else have this problem?  Thoughts and suggestions?

Troubleshoot Crank No Start

  1. Left car unused for 2 weeks; was running fine prior.

  5. No Codes show on Durametric diag.

Hi Pedro: Is it ok to switch among brands of top tier gas or better to stick with just one? Thank you. Andrew

Fuel additive

I have a 2003 boxster. Should I use a fuel additive to clean sparks and injectors? I am new to Porsche. Thanks.

I have an Oxg Sensor Circuit Bank 2 Sensor 2 issue. The Readout says P2272, P2273 What can I expect the cost to replace this and is it two sensors that are bad?

The Readout says Oxygen Sensor Circuit Bank 2 Sensor 2

P2272 , P2273

What can I expect to pay to replace this (2?) sensor and how hard it it to do myself and how will I idenify which sensor (s) is faulty?

 

Is there a part number that I can use?

 

how to drain fuel

Hi, I've been trying to drain old fuel out of my tank since last night and have had no luck.  I tried syphoning out of the filler, but i can't seem to get the tube down far enough to reach the fuel.  I've also tried doing the jumper trick on pellican parts, but i can't seem to get that to work either.  The battery has been painful to charge, though it's less than 1 year old, so I can't rule that out as a contribuing factor.  I can get the car to chug, but haven't dared to try to fully start it with the old fuel.  I have 1/2 tank of fuel that has to adios in order to start the car and replac
