Another weekend and another project I have questions about....
I bought a fuel tank sender O ring to install on the car because I'm quite sus on what I've got now.
1. No "whooosh" sound when opening fuel cap
2. If I fill up full tank, there will be a small leak under the car and it comes from the top of the fuel tank, dripping along the side. Stops after a short while
3. Hot days = 50/50 chance to get high as a kite inside the cabin if the car was in the sun for too long
This is what I bought: https://www.amayama.com/en/part/nissan/1734279900
My plan was to just replace the O ring but I've got some questions:
1. Does the whole fuel pump assembly need to come out for me to replace the O ring?
Or, could I unplug all the connectors and fuel lines at the top, take off the twisty part (17343) and put in the O ring from the top?
2. Is it a very common thing for everyone to just change the pump whenever doing this?
I see the Walbro 255 gets thrown in a lot but I've got no issues with my pump so far. When I did the tune, I asked the guy to check my fuel pressure and he said there were no issues too. But is it just a good idea to change to the 255 anyway as the old unit may have been in there for so long? The 255 seems to be a direct fit for GTT (I got no soldering iron)
