Hey folks, I've had a bit of an intermittent issue with fuel of late when starting after the car has been sitting more than about 12 hours, occasionally after sitting a long time the car would crank for up to 10 seconds before firing, I've suspected air is getting in to the fuel lines somewhere, so I decided to change the fuel filter today.
The current filter is a Ryco Z332, I had heard things in the past about these being a problem but nothing concrete, so rather than grab another one I shelled out for a genuine Nissan filter. Not cheap at $46 but I figure it could be cheap insurance vs. killing the injector pump with air.
Anyway, I don't have pics, but the Ryco has a different type of seal compared to the genuine Nissan filter, the Ryco seal looks for all intents and purposes the same as any old oil filter, flat and about 5mm wide, whereas the Nissan filter has a flat seal about 7-8mm wide, but with a 2-3mm "D" moulding on top of the flat seal.
I imagine this "D" section of the seal is to create a high pressure point on the seal, rather than with the Ryco where the seal is across the entire flat face, I also noted with the Ryco seal that it had rolled over just a little which could mean uneven pressure across the face of the seal, time will tell whether this was the issue with air getting into my fuel system, but I've been over the rest of the fuel lines and can't fault them.
