Help finding a longer version of this screw

[mc1984ss]

This is one of the screws that holds the fuel and brake lines to the frame rail. It has a 13 mm head and is a self tapping design. Where can I find some longer versions? I need to put some spacers behind my custom fuel lines

Hardware store, metric section. Those are M10 bolts and pretty common.

Inline tube sells them.

With a 13mm head that should be an 8mm screw with either a 1.00mm or 1.25mm pitch. Don't have one in front of me at the moment. I want to say 1.25 off the top of my head though.

Since there already is a hole, you can tap the hole and use a bolt. The self tapping part of the screw is no longer required.

It is not a typical metric thread, it's very very coarse. I would tap the holes to the next closest size but most of the holes are impossible to drill or tap with the body in, unfortunately

Coarse pitch, 1.25 as I recall. Got mine from the local autobody supply shop. Maybe McMaster-Carr carries them?
