Thread Size adn Pitch of KGParts Fuel Rails

[KGP]

I get this question 10 times a week. Hopefully posting this info will cut down on people asking this question.

Here is a picture with the dimensions of the rail.

Rail is tapped for 3/8 NPT

To connect to your choice of AN fittings you would need a fitting like this:

These are adapters to adapt a NPT thread to a AN thread.

for more info on AN and NPT threads, please see this page in our injector-rehab knowledge base
