Although I'm leaving for Monterey for the Ferrari events tomorrow, I
still wanted to work on my car today and get that pesky fuel leak fixed.
I originally planned on doing this last Friday, but Geoff at Partsource
was temporarily out of stock. Luckily, he got some more in a couple of
days, and sent me my hose.
Not wanting to have leaks again, I asked around to see what people
use to seal these hoses. Although François doesn't use anything
to seal is hoses, I was not having any luck, so I was looking to see what
other people use. One suggestion came from fellow restorer to use a product
called Hylomar by Permatex. Luckily, my local Napa Parts store had some,
so I got to work finishing the fuel lines. Thanks Lance!
The Hylomar stuff is blue and very sticky. I managed to get it EVERYWHERE!
At first I didn't want to use too much, but after putting everything together,
I found one fitting still leaking, so I had to take everything apart again!
The fitting you see pictured here screws into the yellow fuel hose, and
is supposed to be good to go, but I wasn't having such luck.
I also would have taken more pictures, but I didn't want to get Hylomar all over my camera!
Checking for leaks required me to connect all the hoses, and pressurize
the fuel system with the electric fuel pump. Once the system was pressurized,
I have to crawl under the car and watch for leaks. The first time it leaked
today, I was half way installing the exhaust when I noticed a drip. On
my second time, I gave the system a good twenty minutes of sitting with
pressure to make sure there were no leaks. Unfortunately another fitting
started leaking at the fuel filter! After 2 1/2 tries, I think I stopped
all the leaks. Only time will tell if things are finally fuel tight!
Last week I was showing you how I found a carbon brush to replace my
worn out one.
This week I installed it. This also gives you an idea of where and
how it's mounted. The shot is looking up under the dash at the steering
column. The carbon brush rides on the brass collar which allows the circuit
to continue up the steering column to the horn switch.
