Rusty_S85 Posted August 6, 2021 Share Posted August 6, 2021 The 1/4 in replacement line I got seems thinner than the original. Any idea exactly what the diameter of the original is? 5/16 or bigger? Can I use the 1/4 in or will that restrict the fuel flow into the carb too much? should be 5/16" hardline. That is what is on my truck is 5/16" line from tank to carb. Going to be replaced with 3/8" hardline as 5/16" is too small for high volume high pressure EFI pump. For a carb 5/16" would be fine for a stock or fairly stock engine. 1/4" I dont think I would trust it, I think it would be too small for the volume you need.

Bullnose Gator Posted August 6, 2021 Author Share Posted August 6, 2021 Now I'm stuck, literally. I figured out that it was 5/16 and I recreated the line. I drove it back to my home town 2 hours away with no problems. And then...the next day I noticed that it was leaking from where the filter goes into the carb, so I tightened it and stripped it out. It would almost get tight and then loosen again. In hopes that it was just the filter that was stripped, I got another filter (the one pictured) and the same thing is happening, it won't tighten. I assume I stripped out the female part of the carb? That would mean replacing the carb, I'm sure. If anyone can help, please do. I've really made a mess of this one. Thanks.

Yes, you've probably stripped the carb. But I don't think you'll have to replace the carb. Dorman used to make a repair inlet fitting for that. I believe it had oversized threads and was self-tapping, meaning it cut new, deeper threads. Here's one such but I don't know that this is it: https://shop.advanceautoparts.com/p/dorman-help-self-tapping-carburetor-fitting-1-in-inlet-55140/17190380-P. Someone like Jim or Bill will have to tell you what the inlet fitting size is. Link to comment Share on other sites More sharing options...

Judging by that link, it looks like I would need to switch to an inline filter, no? Link to comment Share on other sites More sharing options...

Yes if you use that fitting, but I don't know if it is the right one. But there may well be others available. Let me see if Jim knows the thread size.

Bullnose Gator Posted August 6, 2021 Author Share Posted August 6, 2021 I really appreciate it. I looked up new carb options just in case it comes to that and noticed that some say non-EGR. Since mine has emissions rigging, does that mean I should stay away from those? Link to comment Share on other sites More sharing options...

Let me see if Jim knows the thread size. As I recall, the thread pitch was 7/8-20 in the fitting used to 1" wrench. I did buy the oversized repair inlet from dorman, but that was many years ago, and I don't know where the invoice is. I'll take a look on dorman's website, to see if I can find a part number Link to comment Share on other sites More sharing options...

ArdWrknTrk Posted August 6, 2021 Share Posted August 6, 2021 Thanks, Jim. Don't quote me on that. It was a decade ago, and my thinker isn't nearly as sharp as it used to be. I am trying to poke around at Dorman. I'm not sure if they even list the fitting I used anymore. Link to comment Share on other sites More sharing options...

I'm not finding anything on the carb inlet fix. https://www.dormanproducts.com/pages/resources/catalogs/dorman.aspx?origin=topnav Link to comment Share on other sites More sharing options...
