1981 Bridgeport 225 Bleed lines
Time to get this baby out of mothballs! SN 5894570. Last time we fired it up was 20 years ago. I don't think it has many hours on it, but then you never know where it went before you owned it.
Some of the bleed lines are cracking. I did find a thread about Tygon, etc and ordered the stuff Ray recommended from McMaster Carr.
My question is the best way to replace all these. Just fish them out really carefully and replace one at a time?
Thanks,
Mike, Colorado

Welcome to the site. One at a time is the smart way. If it goes south I'm sure we have a drawing somewhere.

^^^ya beat me to it
Yes, do one at a time unless you know them or have the merc book/diagram. Tygon sucks long term but it looks cool. Put some 2 stroke oil in the cylinders and slowly turn it, or corrosionX to make sure the rings are free if its been sittin for 20 years!

Yeah it was protected indoors so I'm thinking it is OK. Cleaned out the carbs and fuel tanks. Probably revisit the wiring as that can almost always be improved.
It had a nice Merc water-separating fuel filter but it was put in backwards! Never noticed that but it is fixed now. Probably still filtered, just caught the gunk on the outside of the pleats. We don't get much water in the fuel here in Colorado.
I think the bleed lines I bought might qualify as cool, they look like a pale green/yellow in the picture.
I do have the factory manual which has pictures which resemble spaghetti in someone's stomach after a meal ( - :

Dig that your keeping a Bridgeport alive. What's it going to push. I run tygon and hasn't let me down. Right in paying attention to the carbs and main jet size. Compression check, a look at the reeds and change the fuel pump diaphragm if your not running a electric fuel pump.
Hammer down.

Fuel pump service seems like a good idea. I'll talk a little more about the hull when I get some pictures. Might have some Kodachrome prints around somewhere from 20 years ago but I don't feel like finding and scanning them.
Is there a place for a temperature sender on this mill? I notice it has a high temp warning circuit, maybe 2 of them but nothing else.
