'56 Mark II Exhaust System

[Jaimemarkii]

Hello everyone,

I ran into a problem while replacing the exhaust system on my '56 Mark II.

I purchased the complete stainless kit from Waldron?s Exhaust systems. He claims it's an exact fit. However, it appears that the tailpipe on the drivers side is about 1/2" from the rubber filler tube which to me seems extremely dangerous. Am I missing something? Any suggestions?

Any feed back would be gratefully appreciated.

The drivers side rear rear muffler is indeed 1/2" - 1" from the filler hose. It may sounds like madness but they are all like that (that's certainly what I thought when I first saw it). I know some people split a piece of hose and clip it over the filler pipe to "double wrap" it above the muffler. Having said that there is no history that I know of regarding MKii's catching fire due to petrol ignition or any other reason. I've only see two photos of burnt out cars, one was in the recent California bush fires (https://www.markiiforum.com/showthread.php?9439-Lost-in-California-wild-fires&p=53021#post53021) and the other was an old junker with no cause stated.

If you have any doubt about the condition of your filler hose (hard, surface cracks etc.) then replace it. There's a posting on the Forum I made describing how to do this (https://www.markiiforum.com/showthread.php?9335-Replacing-the-fuel-filler-hose&highlight=hose). The replacement hose from Jack R. fits perfectly.

I would however recommend isolating the battery when its not being driven because many of the circuits are live even when the ignition is off (65 year old wiring and a high current battery are not a good mix). My car is fitted with a remote activated 200 amp solenoid so one can isolate/deisolate the battery from a switch below the dash.

Hi Jamie,

The Forum shows that you own 2686 and 3090, both '56's. Do you mind sharing which car this is?

Hello Jamie,

Mark is right, the small distance between filler hose and tailpipe is not a bug, it is a feature :D.

Even I, like Mark, have not heard of a car burned out of it yet.

Nevertheless, I pulled a fireproof cover over the filler hose.

Pat, I'm referring specifically to 2686.

I also concur, the proximity to the exhaust is less a problem than you might think as the system cools significantly by the time the exhaust gets to the tip. Besides, the door sills absorb most of the heat before the exhaust gets past them.

I've used this on Mark II exhausts under the sills. This is the '33 Continental I'll be showing Sunday.

While you're in the area make sure your vent lines on the gas tank are hooked up and clear. Insects like gas vent pipes, for some reason.

Great idea... I shall fireproof the filler home asap! Thank you Holger

Barry,

Is it like a sleeve? Where did you purchase it? Any idea where I may find it in the Seattle, WA area?
Thank you for the suggestion.

Great explanation and recommendations. My wife is more at ease!
Thank you again Mark.

It's for the 2686... I just finished the brakes, including the master cylinder. The fuel pump was replaced as well.

As Barry mentioned, the often forgotten gas tank vent lines (front and back) join into one 5/8" steel pipe where they cross right over the drivers side muffler. At either end of this short section of steel pipe is a hose (one right angle hose into the rear fender cavity and the other end has a short straight hose joining the outlet of the vent tee). I'd be more worried about a petrol leak there contacting the muffler. Anyway I had to replace it all on my car as the rubber sections were disintegrating.

Agree the exhaust is a bit cooler by the time it gets to the muffler ..but many of us have fitted exhaust socks/wrap on the pipes behind the rockers so that heat has been elevated somewhat for the rear exhaust system.

Jaime; a) please post a few pictures of your garage/cars. b) with that many classics how long is your car maintenance "to do" list!?
