I replaced the O-rings in the quick release tabs on the fuel filter.
I had the injector rack off, and the line still had a bit of fuel in it.
I blocked off the fuel pump end of the filter.
Then I blew into the line up the injector end to see if petrol was still pissing out through the tabs on the 3-way.
I was fairly easily able to blow the fuel out somewhere, not through any leak around the filter, which was tight as now tab-wise. I heard bubbling after that, I guess in the tank (hard to know cause I work alone). No fuel pissing out anywhere. When I blew slowly, no resistance. When I blew hard, there was considerable resistance.
Should I be able to blow fuel and air back through the pressure regulator valve in the fuel sender unit with just my lung power?
I have fuel pressure issues...I just replaced the sender...they are expensive here in Saudi Arabia, even second hand.
Please enlighten me. No talk of computers. I live in the middle of a bloody desert.
Thanks for your help. The good-natured people on this forum have given me many years of happy motoring from what was a complete wreck when I got it. You love it all the more when you fix up everything yourself.
It is a 2005 VZ Executive, known here as the 2006 Lumina. Readers may be interested to know there are huge piles of Commodores lying around in the desert wreckers here. Enough to keep you all going for years. Perfectly preserved in the desert environment. Parts off them are dirt cheap.
