Hi Josh,
Yes, it is hard to work in high heat and humidity. I try to get out to the shop early here in Vermont this time of year. I'm usually out there by now... uh oh it's almost 5:30... I should have been out there by 5:00. Well, hang in there. My mentor, Ken Bailey used to say if you get one bolt done a day that's progress and it will take whatever time it takes. Just think about it, 2 bolts for Ken CT and remove a fuel line. You can do that standing on your head. He might sound crabby to you, but he's a generous and knowledgeable man who is really trying to steer you in the right direction. He really needs that fuel pump core to rebuild and help somebody else. Keep drinking water and turn a few wrenches. Best wishes, Toby
