Only one side fit. Luckily it was the one i needed most. The supply side would not thread in.

Didn't fit my truck but fast shipping

Worked like a charm! Thanks again!

Works great.

Was not needed ad suggested

These are apparently made in China and have terrible machining but are both usable with a little work. The smaller adapter will fit onto the fuel line but not into the TBI adapter. The reason is that the threaded area is simply to large by a few thousands. This is enough to make a big difference in such a tight place such as a fitting. How ever the thread pitch is correct. I used a small machinist file to slightly file down the top of the threaded area and then in the thread grove to increase the thread depth. I finished up with some course "valve grinding compound" by coating the threads and screwing the two fittings together many times to "mate" the two fittings. This worked well and I was able to use both adapters.

The seller was good and the product was for the correct aplication. The quality of the product was not good the female threads inside the body of the fittings were very rough and the end of the male end was rough as well.
