I have a 57 T-Bird with the 312 4V, with what I believe is the original fuel tank, and a card that was put on 3 1/2 years ago. It started running really bad. The float on the rear bowl was sticking. I had to have the crap cleaned out of the fuel bowl, It is a 4150 list # 1850-9. During the cleaning process, I was shown tiny cracks on the inside of the fuel bowl and metering block. They appear to be surface cracks, but there also what looks like tiny bubbles in the casting. I was told by someone I consider very knowledgable that the current Holley carburetors can't hold a candle (quality wise) to the older original stuff.
I also found out that the fuel filter on my recently acquired 57, did not have a cartridge/filter in the filter bowl. This allowed the fuel bowls of the carb to get loaded up with all kinds of crud from the tank.. Until I can get a period correct filter, we installed an simple AC in-line fuel filter. Fast forward 1 week: After driving it for a total of about 20 miles,with the brand new filter, the float on the rear bowl was sticking again. After taking the bowl off, it was once again full of $hit. Seems that the new modern filter that we put on is not stopping the junk from the tank. As it turns out, when removing the rear bowl, we also found that the hair line crack was more than a surface crack. It went all the way through to the outside and is leaking. Now I definitely need a new carburetor, but I also need to replace the fuel system as well. There's no sense in putting a new carb on there, without doing the tank, as it would just screw up the new carb with the same crud. I cannot believe the absolute piece of crap this 3 year old carb is. I have always thought Holley was a top of the line product. I was told that they had some quality issues when they transferred production over seas. Does anyone know if they have been corrected? I want to get an 1848 465 CFM to replace what's on there now, but not if it's going to be the same type of junk that this one is.
My second question. I have been told that it's the fiberglass sock over the fuel pickup that is probably disintegrating and that is the junk coming from the tank. Well the tank is almost full of premium, and I don't feel like throwing out 18 gallons. Does anyone know of a filter that will properly filter the gas as I siphon it out of the tank.
Update: A couple people recommended that I give Holey a call and see if there is anything they would do. Well I finally got a chance to call them today. I explained the situation to one of their Tech Service guys. He asked for the List # and the date code. He said that back in 2006, Holley had a problem with castings from a new vendor. Can you belieive it, the list # and Date code fall within the problem range. He told me to pull the carb, and send it to him. He will check it over, and if, as he suspects, it's related to the casting issue, he will send me a new carb. Does anybody have a good way to send a gas soaked carburetor through the mail?
