I have just fixed a fuel leak coming from my fuel filter.
The flexible hose run just over the valve cover and was totally cooked (crumbling), I was quite lucky that it did not catch fire...
Here come the questions:
Should I re-route that line, if yes where?
How to get the air out of the filter? It is mounted horizontally so traps air like crazy, should I mount it vertically?
Having some air in the filter doesn't really hurt anything. I too agree on metal line, and would rather see a metal filter. If you can see the fuel, it means the material is more likely to break or leak. The filter also doesnt have to be horizontal.
Might I add this: And this is general statement and NOT directed at anyone....OK!
BE CAREFUL in what you buy for a filter. Even though a filter as shown in the above photo in POST #4 may plumb in and work. You really need to VERIFY what the micron rating of the filter actually is by calling the manufacturer if that data is not available at the place you buy it. MANY of these nice steel filters that you can plumb MAY HAVE A 125 micron rating (which is used for FUEL INJECTION) and NOT a 40 micron rating which is what can be used for a carburetor.
'Jazzyced',
I have had to plumb in new fuel lines in numerous Corvettes with the same type of carburetor you currently have on your engine. And the one thing that 'pisses' me off is that when you read that the carburetor manufacturer wants you to use a rubber hose going to the carburetor.... I feel is a bunch of crap. ( Unless they have changed their recommendations on this). I feel it is due to the material around the fuel inlet is not that stout. BUT...I have made several..and when I do...i make sure that I incorporate a support bracket if some kind to make sure any stress on the line going to the carburetor is reduced.
Thanks for the good piece of advice, I hope I will have time before the weekend to buy a proper filter.
I also noticed 2 more old fuel hoses going from the steel lines to the pump... Given the amount of dust and how flexible they are, I would not be surprised if they were leaking too or on their way to leak. They do feel like they are going to collapse any time.
With all the dirt and debris I have been pumping in the engine lately (leaking fuel lines from the tank, tank had to be removed, leaking filter lines, etc...), I have the feeling that I have very little choice but to clean the carburetor correctly after replacing a few obvious parts.
The carb is oily/greasy (inside and outside) and I can see dirt in it.
At least I am learning something new everyday and this makes me happy.
Spot on, it is an old Edelbrock 1406.
I like what you did, very clean and tidy.
Did you get the air intake from Edelbrock as well?
The carb on the 1967 is a 1406. The banjo fitting and filter are Edelbrock. Air cleaner is Edelbrock as well. I bent and flared (AN 37* single) the pump to filter steel line. SS fittings are from Russell.
You are correct in that you have to do something: the 1406 does not have an internal filter like the Q-Jet.
Just in case you were not aware of it....the fuel hoses you have down by your fuel pump are special molded 'S' hoses that you can get from a Corvette vendor. I would NOT use hose off a spool for these two hoses.
Also...keep this in mind because YOUR photo of your engine....and the photo in POST#4 and the photo in POST #7 all are obvious different.....BUT the ONE thing that is IMPORTANT is where the HEATER HOSE in each of these three engines is located and how it effects the fuel system. And the heater hose I am referring to is the one on the top of your intake on the passenger side...and the one on the top if the intake in POST #4 and how the heater hose in POST #7 is in the front of the intake and not in the way of plumbing in the fuel line.
KEEP this in mind when and if you plumb your system.
A beautiful job in 'paul 74' did for his fuel system...and I believe it was installed but not in the frame of when it was photographed is a bracket or strap to make sure the fuel line is solidly mounted.

Dub,
I can't remember if I used a bracket or strap. I don't think so as it is solid steel from carb inlet to fuel pump. But I did the job ~10 years ago! Memories fade. I can say it never gave me any problems.

I could have sworn that you had posted this photo in another post some time ago and remarked that the fuel line was secured but was not in the frame at the time the photo was taken.
Either way....providing an added support is wise to do.
