Thanks, George. Will give this a try. Been looking into the spring loaded seals, but a bit pricey for now.

Great. Thanks for the information. It looks like the seal and O-ring went in the correct way, but the spacer went in backwards. Appears the O-ring should fit it the machined recess on the spacer.

Could you just replace the floats with these new floats from Aircraft Spruce?

Is this it?

Reviving an old post. Does anyone know which way the spacer (ES4141) and the O-ring (ES4140) goes in? Does the O-ring fit into the groove in the spacer? There is a small recess that looks like the O-ring goes into, but not 100% sure this recess is for the O-ring or the orientation of the spacer.

Thanks for the input/recommendations. Will see what kind of prices I can get.

Is it in fact an "air" bubble? Could it be fuel vapor? It doesn't make sense to me that air could be "sucked' into a fuel system that is pretty much gravity fed. Did something change? Could it be the fuel system is getting some sort of vapor lock from getting too hot at that point in ...

Looking for recommendations/suggestions on a replacement alternator for our '48 170. Existing is a Ford 60 amp alternator on an 0300D. Thanks in advance.

Has anyone ever had the rubber boots on the push rod tubes start to slide away from the lifter housing and move up the push rod tube? Found that 3 boots started to do this on our 0300D. All new boots and clamps were installed at TOH.

According to the parts book, the starter is # 1109656. If you have this starter, maybe this link will help. Note the last post in the thread.

Thanks for the help. Will try it this weekend and update.

Not sure on the "O" ring placement for the different thru bolts, but the "O" ring that we suspect is leaking is on the thru bolt that goes thru the case and secures the cylinder bases to the case. It's on an 0300D.

I know this post is old. It appears we are finding a few more oil leaks. It appears there is an oil leak at the base of #6 cylinder, between the bottom cylinder base stud and the thru bolt at the 4 o'clock position on the cylinder base. It looks like it is either the cylinder base "O" ring...

Thanks, George. That's what made us remove the tach flange originally, to correct an oil leak there. Hopefully, this will correct the leak.
