I got the fuel pump replaced on the 93 90qs. Not really a bad job. Thanks
Frank for the tip on removing the pump from its cradle. Without your tip I
would have gone to buy the darn 3214 since there was not way that thing was
going to budge out of its cradle.
However I would caution anyone doing this job to ensure you have more than
adequate ventilation in the area you do the work. The fuel fumes are
everywhere. I was concerned about my shop light switch causing a spark that
would ignite fumes. Obviously it did not happen. But when I dropped the
light over the open tank with some fuel still in and caught it only a split
second from it shattering over the open hole (cause I had a large metal
screw driver lying across it and the protective cover had come off the
florescent tube which was now exposed) I had to take a break to reassess
the situation. So, be careful out there.
Thanks for all your advice
