Good deal on the EGR - that f'ing light greets (for a minute) me every morning just as I hit the highway.
I have a weak pump and posted the question last week. Check out (click on more from me...) the thread. I got some pretty good explanations of replacing the pump. It does not sound too easy, but I may as well give it a shot. Unfortunately I just sold my "spare" '90 900 so I no longer have a reference tool or backup ride.
As far as checking fuel delivery pressure, I'm reitterating from Bentley. Apparently you can connect a standard guage at the fuel rail to test, but I'm working my way to this one. I'm assuming no new washers or anything special is required.
My pump is suspect because of the humming and bearing melody it makes. If yours is quiet, it may be ok. Since you mention the 1/2 tank or lower symptom I wonder if you don't just have a restricted fuel filter or faulty pressure reg. I'm doing the filter this weekend - it needs a change and I always start with the cheaper DIY's first. To check the regulator, pull off the vac hose on it when the car is idling - if there is fuel in the hose or if any comes out of the regulator nossle, then its shot. I don't know from experience other failure scenarios of the FPR.
Your leak. Are you sure its tranny? Both my crankseal leak and power steering leak showed up by dripping off the back (front) end of the tranny case. For the plug - its either a 1/2" square (use a 1/2" socket adaptor or just a 1/2 socket wrench w/ no socket bit) or a 12mm hex. Good luck finding a 12mm hex socket - even Sears failed me. My base 900 had the 1/2, the SPG has the hex. I ran Redline and Amsoil on separate occasions on the 900 base, and I'm putting Redline in the SPG this weekend.
Have a great weekend.
