    2003 tundra v8, last time changed fuel filter had to actually cut the metal line as the ends froze up like they do, rubber on it for now but would like to get back to metal. What is the actual size of the fuel line? is it metric ? / measures out to look like 3/8 but not sure, need to get to:
    old line/ compression fittings, fit the new line in and then fuel filter...repeat for other end...not best description but most of you know where i'm at...anyone else done this repair?

    Sounds like you need some type of slip compression repair fitting. Slip the fitting down the good part of the line and slip it back up to make your new connection at either the fuel filter or new line running out from said filter. You’ll do this on both ends/sides of filter.

    Or, couple new filter and one side (like normal) and slip repair the long splice end with the slip compression fitting.

    A 3/8" fuel line measures 9.53mm outside diameter.

    Steel fuel line repair kits are available, but I can find no reference to any 10mm fuel line repair kits. In fact, Dorman Products catalog lists no steel fuel line repair kit for any Tundra. If your caliper is truly indicating 10.00mm, then a 3/8" fuel line compression fitting may work IF (Big IF) you can get the 3/8" compression ferrule to slide onto the 10mm line. I doubt it's going to happen, won't know until you try it.

    I hate to say it, but if you want an all steel fuel line (the safest option), then you're probably looking at replacing the entire fuel line. The only other alternative I know of is possibly having a shop repair the section by flaring the tubing ends and using metric fittings ($$$). Replacing the entire line may be cheaper.

    yeah thanks, that's alot of same info i 'm finding...I have found a compression fitting that will go from 10mm to 3/8...so may just be looking for any make or brand that has a 3/8 line with threaded fuel line/ filter. could use anything after that, ford, chev, etc...just have to write down the part number in my book for next time...i have a flaring tool, but i bet it would take alot of hit/ miss tries to get it right, don't feel like fixing that many leaks....if i don't find something to pull from local junk yard, i 'll go with the 10mm to 3/8 fitting...thanks for digging into that..

    If you've found a compression fitting for adapting 10mm to 3/8", you are close. Take a look at this 3/8" steel repair kit by Dorman: https://www.amazon.com/Dorman-800-1...ne+repair+kit&qid=1560212229&s=gateway&sr=8-3

    You can always go with the GM GF-652 filter shown, but then you have to get back to 10mm tube on the other side...another compression fitting perhaps? Tube length in Dorman kit is 18". Good luck.

    thanks, well found out the tubing changes size just before the filter, it seems to go from 10 mm down to actual 5/16 tubing....now all i need to do is buy any filter that a 5/16 fuel line goes into, should be easy to find an SAE filter on another make ...Ford / GM etc...thanks for all the help..
