question about changing fuel filter
76 Olds 455 engine, 4bbl carb
The fuel filter is easy to get to, on the front of the carburetor. It's a small paper cylinder, open on one end, closed on the other end. There are a couple of fittings to unscrew then the fuel filter inserts into a small metal tube. One end of the tube goes into the carburetor, the gas line from the fuel pump connects to the other end. There's a spring to hold the fuel filter in place, under some tension. I didn't take it off the car, somebody else did, or I wouldn't have this problem. If I had taken it off, then I would know how it is supposed to go back together. There are 4 possibilities, and 3 of them must be wrong! There is no indication on the fuel filter which end goes in which direction. My guess is that the open end goes towards the fuel pump line, the closed end goes towards the carburetor. Correct? I'm guessing the spring goes on the carburetor side, to press the fuel filter against the intake line from the fuel pump. Correct? This is my first visit to this group, and hope this is an appropriate question. Thanks. |

pump line, the closed end goes towards the carburetor. Correct? I'm guessing the spring goes on the carburetor side, to press the fuel filter against the intake line from the fuel pump. Correct? Yes and Yes. I had the same mental question a couple of weeks ago when I took my fuel line off the carb. It was cold and I wasn't watching closely, so when it came time to reassemble, I had some figuring to do. You probably know to use a two wrenches for putting it back on. careful you don't twist the fuel line. ....thehick |

Also, thanks for the caution, which comes a few years too late... I already twisted the fuel line, a long time ago, but not too badly. It still connects OK. I know how to do it correctly with the 2 wrenches now - very slow, easy, and careful. Herbie |

There were repair kits sold in auto parts stores to help you get back in action after you had screwed up the casting. This is from memory, but I believe it is accurate. |

Actually, the best thing to do is simply cut the fuel line about an inch or 2 back from the fitting. Then install a see thru inline gas filter as a primary filter. When you need to change the little filter at the carb (which won't be very often) you simply unscrew the whole thing - you never have to mess with unscrewing that line fitting again. -jim ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |
