Update:
Reinstalled my p-mags after getting the recent update and decided to tackle the fuel pump heat shroudl, which requires removal of the fuel pump.
Getting it off is straight forward - betting it back on, uhhhh.... not so much. Man o man, what a chore. Per previous posts, the fuel pump body interferes with the socket head bolts so that you cant just line up the bolts with the threaded hole in the accessory case - you have to shove them half way through the holes in the flange on the pump first (past the point of interference), then position the whole pump up against the accessory case and hope for the best. You cant even see the bolt or the hole its supposed to go in on the far side of the pump. Throw in the extra hassle of the loose heat shroud around the pump and it quickly becomes an excercise in frustration.
Also, I dont know who is making the heat shrouds (I got this one through ACS), but they might want to actually install one of their products. NONE of the holes they put in the sides to accomodate the various fuel line fittings were correctly placed. I had to hack out all of them. I would have preferred to have gotten it with no holes at all so I could have put them in myself - in the right place. The shroud also interferes slightly with the mounting bracket for prop governor, whose position cannot easily be changed.
Baed on the earlier posts, I was concerned that the arm on the pump wouldnt be postiioined correctly under the little rod inside the acccessy case that goes up and down. I turned the prop until I could push the rod up, but it slid back down in just a second or two once I took my fingure off of it, so there was absolutely no way to get the pump mounted in that time. What I did figure out however is that if you can get the pump properly positioned against the accessory case, and be fortunate enough to get the bolts lined up just right so that they screw in with the allen wrench, then the arm has taken care of itself. I dont think its possible to have the pump perfectly positioned against the accessory case and the arm not be correctly positioned.
Well, tried and tried and tried again to get the pump with heat shroud installed and succeeded only in partially stripping the threads on the accessory case holes. Fixed that with a tap, and tried again over and over and over. No real recipy for success - the stars were finally in perfect alignment and it just happened. TIme to quit for the day.
But wait - the fun has just begun. Want a real challenge? Try doing the safety wire on that socket head bolt on the far side fo the fuel pump - you know - the one that you cant see. I saved that for the next day. I used a mirror, and a hemostat to hold and thread the wire through the hole, then a pair of real small vise grips to snare the end of the wire and pull it through.
It took me three hours to get that safety wire done. The good news is that I am now also fully qualified as a neurosurgeon.
Well, sorry for the rant. Just want to warn you if want that heat shroud, well, you better REALLY want it.
