    Okay so before I get flamed for this the issue isn't for my Tacoma but my dad's 98 Ranger. Either way the repair aspect for it can still apply for the most part. In a nutshell I need to know if it is okay to use this type of Dorman plastic fuel line connector with fuel injection rated fuel hose. I know it says for Nylon fuel lines but can they still be used in a rubber hose with fuel line clamps? Or with they break when clamped on? They have to be fairly durable because the Nylon line is forced on over the barbs.

    These are the Dorman connectors I'm talking about

    Now for the reason for the repair.

    My dad finally decided to replace his fuel filter on his 98 Ford Ranger with over 190,000 miles. So yes original filter even though rec. replacement is 30,000. Well at this time Ford used a shitty type of metal "quick" connect on either side of the filter for replacement. His are rusted to the stub lines on the filter. After 2 hrs of trying to to get them free using the tools and W-40 he cut the fuel lines on either side at the stainless hard lines. So today we went to NAPA and got some Fuel Injection rated fuel line 5/16 and the special clamps. He wants to use the plastic replacement quick connects if possible. I have no clue because this is my first time ever repairing a fuel line. So far all we bought was one of these because it will work too.

    Anybody with fuel line repair experience is appreciated. Oh and buying the factory lines is out of the question so don't bother.

    They are designate for nylon fuel lines because in many cases you slip the barbed end into the nylon line, and then use a hair dryer to heat the nylon line, allowing it to form fit better. Can they be used in a fuel rated rubber line with clamps? Technically, yes. Personally I don't like to use clamps of any kind on a fuel line. There is always the risk of a clamp loosening over time, and the last thing you want is a fuel leak. That being said, am I to understand that your dad's truck has nylon lines with the quick connect fittings that snapped into the metal fuel filter? If that is the case, you should be able to use the Dorman nylon repair fittings on the original lines if he did not cut too much off of them. Any chance you can take some photos?

    No his Ranger does not have the newer Nylon fuel lines, just the stainless steel hard lines.

    That is going to be a challenge to do a good and proper repair. Maybe check with the parts store to see if they have a repair kit for the metal lines. While you can use rubber fuel lines in a pinch, I never recommend using them as a permanent repair.

    Yeah they didn't have any compression fittings for going from steel hard line to nylon. All the local stores have line repair kits for nylon lines. More than likely this will become the "permanent" repair because this truck isn't in the best of shape. If this holds together with this repair for 2-3 years that will be plenty. The plan is to lift up and move the bed back to access the rear section of fuel line to the hardline there. Then push on the 5/16 rubber line on for about 4 inches and use 2-3 fuel line clamps. On the other side of that section at the filter use one clamp because whatever replacement quick connect we use has either a flare or barbs on it. Then on the front section like the rear, slip the rubber hose about 4 inches over the hardline with another 2-3 clamps and another at the quick connect.

    My suggestion would be on the hard lines to make a simple flare to slip the hose over, then add the clamps. That will decrease the risk of a hose coming loose eventually. Good luck!

    Thanks for the suggestions, hopefully Saturday we have this all done. Had to order 3 of the six bed bolts from Ford because 3 snapped off halfway in the stem due ti excessive corrosion. Also O'Reilys had to order those all plastic 5/16 fuel line quick connects. Will take some pics when performing repair.
