CARB FUEL LINE KIT – COMMENTS
Background Story:
I recent days, I have been entertaining the idea of swapping out a Holley 770 Street Avenger, I bought in 2009, that has seen, at most, 20 miles of actual road testing, since being installed during vehicle resto and/or mods later and finally installed in 2015. Prior to this setup, I was using a worn out Holley 750 Double Pumper, c/w a manual choke (1985 through 2009) - that despite it requiring a long overdue rebuild, was far less problematic - during my typical 440 RB Hot start up. It was certainly more reliable, than is the case with my Holley Avenger, that is currently equipped with a factory electric choke.
Yes, it may simply be a case of not having the electric choke setup correctly, or other common factors discussed elsewhere, at length, by so many others, much more knowledgeable on the topic - than me, whose efforts have been to help identify and address, either a single or even multiple causes, for the dreaded "Hot Start" scenario.
In this regard, and wanting to revert back to a manual choke (my preferring to know its ”ON” or “OFF”) I purchased, the recommended Holley Manual Choke Conversion Kit #45-225, for my Street Avenger, which resulted in a total waste of my time, trying to pick and choose between all of the unnecessary brackets and misc gismos, I later determined to be not applicable to my application, no thanks, to what can only be described as a: "1-kit-fits-all nightmare", including in my view, a virtually useless set of instructions, and a piss poor quality diagram to boot! This kit, from a professional carburetor rebuilder’s perspective, no doubt requires little, if any explanation, and perhaps had all of the parts I required, but for all of us DIYs, the lack of clarity regarding all of the part options, including the assembly of the specific parts needed, for only my application, was, to say the very least, a total FAIL in marketing communication, in my opinion.
Now, to the point of my asking for your Comments:
All this grief aside.., a Holley Ultra Double Pumper 750 cfm Square Bore, 4-Barrel,Mechanical Secondary, complete with a factory Manual Choke, Carburetor (0-76751BK) is now being considered for installation.
I am delaying my purchase of this carb - until I get a few other things figured out - such as the following...
One must consider which fuel line kit on the market today, is best suited for my mildly modified 440 street application. Quality, is also important, and something that I am willing to pay for. There are many vendors out there flogging such products, and likewise, an endless stream of buyers, who have posted BAD experiences - involving poor quality, leaks and fuel port alignment issues, given the wide variety of measurements stated by vendors. I suspect a person must be ‘extremely’ careful in their kit selection, given all the confusion, when dealing with variable duel port (center-to-center) distances and the lack of some kits, to properly align, adjust & professionally secure their fuel line kits - to a model 4150 (Double Pumper) - not to be confused with the longer HP version.
I am leaning towards JEGS #110824 Fuel Line Kit as illustrated.
I have also tossed in a photo for fun, illustrating many of the various (center-to-center) measurements reportedly out there today. No wonder, so many people have had problems. Perhaps, I should just build a custom fuel line kit from scratch, using quality parts - although I shouldn’t have to go to all that trouble to avoid the: (9.25; 9.313; 9-5/16; or 9.50 )center-to-center kit selection confusion, surrounding a Holley 750 cfm ultra double pumper carb. Many kits say they are 4150 compatible, but are not 9.313 (center-to-center) - which I believe, is the correct measurement. Some are saying, not even Holley's fuel line kit, for a 4150 model carb fits correctly, on an ultra double pumper. Really? No worries, I'm no longer considering their fuel line kit product anyway, for my own reasons.
In my efforts to make a well informed choice...
