I've got a 289 that I just installed an Edelbrock carb on. All I have left is to hook up the fuel line. I purchased the piece of chrome fuel line that Edelbrock sells for their carbs and now I'm not sure if it will work for me. If I use the Edelbrock fuel line it will be against the heater hose, as will the fuel hose near where it connects to the fuel line. If I hook it up this way, I am ***uming I will have greatly increased my chance of vapor lock. If that thinking is correct, I don't know what to do that won't look crude. Insight/ideas? Thanks in advance guys.
I may be able to(although I prefer not to). Even then the fuel hose will still be in contact with the heater hose. It has GM style HEI so my hose routing is still somewhat limited.
Hmmm I'd run the fuel lines along the other side of the car and wrap around the back side of the Carb. Maybe put a extra bend in your chrome piece?
I'll have to take a look tomorrow and see about that. I know that I will have mechanical temp and oil pressure guage lines to work around, but that shouldn't be a big deal. I also have to figure out where my kickdown linkage will be when I get around to hooking it up(not being able to p*** properly will most likely drive me nuts)
Vapor lock is an issue on the suction side of the pump. Low pressure makes the fuel boil at a lower temperature. You won't get vapor lock on the high pressure side, but could get more evaporation from the carb bowls.
I had the same problem on a small block Ford with an Edelbrock carb. I used a banjo fitting that Edelbrock makes for their carb. The banjo is 90 deg and you can position the fitting in any position. For mine I pointed it towards the rear of the carb and ran the fuel line around the rear.
make up your own stainless steel line over to at least where filter is. that way you can have it not touching heater hose and tuck closer to distributor base and not have that big wide bend you have now with using so much rubber hose.
a little bit of insulation or just something to separate the 2 . fuel line is gonna pick up lots of its heat just radiating up from the intake . something as simple as the boot they sell to insulate a spark plug boot
When I questioned where it would be, I was meaning more specifically how much room I would have and where the fuel line would need to run if I put it on that side of the carb. Also, whether I use stock linkage or switch to cable style.
I guess I was misunderstanding vapor lock. I had been led to believe it was simply the result of too much heat. I was unaware that there was a difference based on suction vs high pressure side of the pump.
As long as there is room for both I would not worry too much about it. In the summer time it's a good chance that you won't have hot coolant circulating in the heater hoses so It won't be any hotter than your heater core in the cabin.
I would route the heater hose forward going under the Ign wires around the front of the head and pairing up with the other heater hose to the core...
Thanks for all the suggestions. I was able to tweak the Edelbrock carb line so that, although it is still close, the only place anything touches is at the fuel hose clamp. I figure I can slip something in there to keep it from ultimately rubbing a hole in the heater hose and it should be ok for now. If it does cause me trouble in the heat next summer I guess I'll worry about it then. I know there is room for at least another 1/2" of carb spacer if I want it. That would gain me a little more room anyway. I started a thread regarding my next obstacle, the kickdown linkage. If any of you have insight in this I'd love to hear it. As I believe I have stated before, this is my first time working on a Ford product where I was not simply replacing a stock component.
