Guys,

I'd really like to disassemble this fuel rail; the bridge tube from the left and right rails. This would allow me to ensure it to be as clean as I can muster. It would appear to be able to be separated, but I can't seem to get it to pull apart. Anybody know the secret?

Thanks. Brad.

The bridge is called the crossover. A die grinder will get it apart......

Ryan,

So, I’m hearing they don’t come apart….?

Thanks. Brad.

Sounds like they do, but requiring permanent modification

DrFeelgood,

Yup. Nope.

Thanks. Brad.

Guys,

I’m planning on changing the oil, just as insurance, in case that stuck open injector has been trying to pump gas into the oil pan. I’ve never changed the oil in a boat, as I’ve always had someone else do it. I had a guy that did it really cheap but did good work. He’s out of the picture now.

Looking at the oil filter, it would appear that it should be fairly well drained. It should actually be a fairly easy step in all this, as it’s right out front and on top (for once). Just wanting to know what to expect. I’m planning on stuffing towels all around it, but it’s going to be impossible to cover everywhere lol might try and go. Can I expect it to play nice as I unscrew it or is it likely to still try and dump oil all over the place?

Thanks. Brad.

Get the oil warmed up. Poke a hole in the top of the filter to get the oil to drain out of it so it won't make a mess. Start draining pan. After a few minutes unscrew filter. It will most likely be pretty tight.

I break the filter free to make sure I can loosen by hand, wrap a couple (I use a couple because one always seems to have a hole in it somewhere) Home Depot plastic bags completely around it and loosen filter until it comes off and is in the bag. I also have a little bucket near to put that mess in right away.

The upside-down oil filters seem like they would make a mess, but are actually a pretty clean setup at oil change time. Just unscrew the filter enough to loosen the seal allowing air to get past, wait 20-30 mins, the oil will completely drain out, and you can then unscrew and remove without spilling a drop.

Get a Jabsco oil change pump or similar and while filter is draining, suck the oil out of the dipstick tube, unless you have the hose that pulls out of the transom drain plug hole. My 502's hold about 7.5-7.75 qt, I usually am able to recover a solid 7 qt. each through the dipstick.
