Fuel Filter

TYS EL · Posted: Thu Jul 17, 2008 9:58 pm Post subject: Fuel Filter

My fuel filter is in dire need of replacement. I think this may be an issue with my horrible gas mileage, among many other things.

I would just go ahead and replace it, but my fuel lines are so horribly rusted that I'm scared they will break if I do so.

So, can I just replace my rusted lines with some sort of rubber/synthetic lines, or do I need to find some new hard lines to replace them with.

You can replace the hard lines with rubber. But they will deteriorate and crack over time. Best to use hard lines if you possibly can. Maybe soak the fittings with penetrating oil before you try to loosen them?

Always use a line wrench on the fuel line. If you don't know what that is, it's a heavy duty box type wrench with a opening for the line. They usually come in a set, SAE or Metric. If you already know this, please excuse my reply.

Nope, I didn't know that doug, thanks! Now I just need to find some hardline, probably save me some headaches later on down the road

another idea is if your using the factory fuel filter you know the little one inline then an idea could be to add a extra filter in the rubber line right near the fuel pump i did this with no real problems plus i got a after-market clear filter so i can watch my fuel going through the filter and actually see how its flowing.

I've been soaking my fuel filter inlet with Kroil, to loosen it for filter replacement. I've just returned from NAPA and CarQuest looking for Rochester specific fuel inlet tools. Someone on the forum said NAPA had a specific tool for the job, as it's a common problem for the inlet nut to get stuck in the body and to round off. There's even a Rochester fuel inlet repair kit on eBay, the removal problem is so common.

Problem is both stores came up empty in the catalogs for any fuel inlet removal tool for non-computer Rochester Quadrajet 1979. Does anybody have a definite source for this tool?

Buy a cheap 1" combo wrench and cut a slot just large enough to fit over the fuel line. You'll need a 5/8 line wrench for the small nut. Hold the large nut so it won't turn and use the hex end of the line wrench to turn the small nut. Don't forget to replace the nylon gasket on the inner end of the filter housing.
