fuel line
Tried to remove the fuel line to the carb a few days ago to change the jets and they obviously hadn't been removed in a long time and were sticking anyways one of them ended up twisting. I've been looking for a replacement, but can't seem to find one that fits, they're all too long and don't clear the intake manifold. 
Anyone know of a part number or where I can get the correct size? Its for a holley 4150 dual feed. I tried summit part number SUM-G3100 but it was too long as well.

Lars wrote an excellant paper on making your own hard fuel lines, w or w/o filter. It might be here or at WWW.corvetteFAQ.com That's how I do them now.

Buy a holley banjo fitting from most any parts store, you can angle it to clear whatever. Get a length of fuel hose or braided steel hose ,fit an inline filter somewhere convenient and run it to the fuel pump.Use extreme caution where you run the line , dont let it get close to exhaust manifold, or anything that moves like a pulley,ect.

It's not that bad I just did mine 3/8 S.S.tubing I borrowed a bender I added an inline filter( chrome Mr.Gasket) I used a compression fitting where it hooks to the fuel pump,1/4 pipe to 3/8 compression S.S.fitting I had to use rubber where it hooks to the dual feed carb line and the fuel filter

I don't think thats even the correct model carb, all I know is that its dual inlet with the inlets 9.25 in apart (which is what made me think it was that model carb) and the inlets cannot be more than about 3 in long or they will not clear the intake manifold, which is stock....any help appreciated.

Although a 1/2" line would be a safe bet, I agree with several of the others here that the stock 3/8" should work fine, particularly if you are pumping at the tank and regulating at the carb. I am feeding 642 HP with a Malory 140 feeding through the stock 3/8" line and regulating to 6 psi at the carb. I use the 5/16 return line for the relief side of the regulator. I have not experienced any starvation.

These fuel lines are all fabricated and bent with 3/8`s steel from the pump to the dual feed holley. Stay away from rubber hose if at all possible. I bend the carb with a 3 way compression union and connect it with a straight compression union to a carefully bent line from the pump. A really good 3/8 tubing bender is necessary. Its tedious, but worth it to avoid any possible leaks. You can do it.

Also try going to a part store like Advanced they have a Mr Gasket dual feed hook up for the inlets for about $15.00 and then see if you can cut your old line and attach it to the hook up with a little rubber fuel line and some worm clamps if you think bending the tubing is a little more than you want to bite off

How do the banjo fittings work? Any pics?
