Fuel system pressure

[richard.hezlett]

I am thinking of doing the "inaccurate fuel gauge reading" fix while my seats are away being refurbished. I wanted to know if the fuel system would still be pressurised after the car being sitting idle for 2-3 weeks. I'd remove the fuel pump fuse ( does anyone know which fuse box it's in ). I don't want the bother of resetting air bag lights for the seats if I turn the engine over to release the pressure. Thank for reading.

Are you taking fuel amount or fuel pressure? fuel pressure is not held for more than a minute or two after switching off the engine.

Just fuel pressure. Fuel gauge reading very inaccurate so I was planning on carrying out the forum guide which involves removing the 2 sender units from the fuel tank. Am I right in saying that if the car has been sitting idle for a while there should be no pressure on the tank? Perhaps taking off the fuel cap would also release any pressure in the tank.

You will be fine. No pressure.

Cheers. Another job on the to do list!

If your removing the in tank units ensure the tank is less than half full & that you do not spill fuel on the o-rings.

Thanks for that advice. Just filled the tank a few weeks ago with the petrol being cheap. Will have to wait a few weeks then.

If your going to wait a couple of weeks then I'd get some new o-rings for the ease or re-installing them.

Also no matter how much fuel has come out the fuel bucket there is always more lol. But as Darren said do it with a near empty tank, saves the smell impregnating into the carpets, seats, your nose.
