suggestions on fuel line fitment - The 1947 - Present Chevrolet & GMC Truck Message Board Network

*vegaschevy* · 08-24-2009, 08:02 PM

I have this new carb i am finally getting around to installing. The fuel inlet is a dual feed set up and the supplied bracket hits the AC bracketry.
I see one of a couple fixes.
A. Put a carb spacer under the carb which may work and provide enough clearance.
B. bend the fuel line a bit which would give it a 45* bend and clear the bracket. (seems like the best)
C. find a flexible fuel line.

If I go with B is their a tubing bender small enough to fit in the available short arm to bend it out accurately on both arms?
DoeS anyone else have a suggestion?

I like the 1 inch 4 hole carb spacer option. 1 the spacer will help out with clearance 2 it will keep the fuel in the carb from boiling. Just my 2 cents worth.

Plus, you'll get a little more HP.
I ran into this problem with a SBC (with a Barry Grant carb), ended up shortening the two lines that go to the float bowls but, I can see that the choke coil is in the way on yours.
I think that bending the two lines would be a good idea, also.

Can you flip the line 180 degrees and feed it from the back ?

Don't laff at me: if you decide to bend it & can't find a bender to work, fill the lines with sand and then bend them.
That will prevent the lines from kinking.
Just be sure they are really clean before you put the line(s) in service.

On the top end of the HP curve, it'll probably lag a bit on the bottom.
Personally, I'm more interested with torque rather than HP.

are those tubes regular steel or stainless? stainless will be a bit difficult to bend
i like the spacer option
another option is a 45 fitting on the carb

Don't bend that line or you may end up wth peeling, cracking and flaking chrome. Use a carb spacer, will probably help with power and keeping the fuel cooler, too. You can find them cheap on Ebay and some even have a threaded hole for a power brake booster or pcv nipple, which is nice to have it you ever need it.
