ahh...  but you will also see if the check valve is leaking at the fuel pump
when the engine is turned off.... or if one of the injectors is leaking with
the engine turned off...

I am thinking of a permanently installed fuel gauge as I do my digitool... a
handy diagnostic tool .... especially in remote areas where I must rely on
myself... (and since I am chemically sensitive it would be nice not to have
to open the FI system and breathe the fumes )... also better to have it
installed already than have to open the system in some windblown sandy patch
of desert where contamination could result...
