Questions & Answers
The vendor should be able to tell you, but here's how to make a pretty good educated guess in this situation: Measure a known dimension on the image on your screen with a ruler or calipers, e.g. the threads' major diameter or tip diameter (which you can find in the standard for the specific feature, in this case a 6 AN thread or a 5/16" SAE tip), then divide the known dimension by the measurement to get a ratio. Then you take a measurement of the unknown dimension, in this case length, and multiply it by the ratio you discovered in the first step. This won't get you down to thousandths of an inch, but it'll get you close enough to make basic purchasing and design decisions.
Yes, Robb, this is compatible with a fuel injection system. Just make sure it has the connector you require. On a 1998 Chevy Blazer with a 4 cylinder engine, I used this. The 3L fuel injection system (Return Line) and the 3/8 connecter on the (Feed Line) are both included. There should be no problems as long as your flare is good.

It would have been better if the locking rim was a little higher or the fitting after the locking rim was a little longer, but it worked for me.
It is well-fitting and does not leak.
Excellent product.
PERFECT! FOR MY BMW 135I, IT WAS USED ON A WALBRO 450 FUEL PUMP MOD.
Great buy.
Fitting was of good quality, and it performed as expected.
It works perfectly and hasn't let me down yet.
This is what I used for my stage 2 fuel pump.
