What size of NPT are the banjos? Are they 1/4&quot; NPT or 3/8&quot;?<br><br>Working on a new fuel system and need to know the thread size to order fittings. 8) I could take one out but if someone knows it would save some time. <br><br>Thanks<br>DB<br><br>

 

I dont really understand what you are saying but ask ROD at WILDCAT. I'm sure he knows and sells all that stuff.

 

NPT=National Pipe Thread. 8)<br><br>DB

 

I'm pretty sure its metric. Not positive on the size though. Maybe 12x.150.

 

They're not pipe thread if I remember when I changed mine out, they're closer to a standard bolt thread.

 

Don't know the size either, but knowing the job the banjo's do it cannot be a NPT which has a tapered thread. It has to be a straight thread. As KATOON said, probably metric.

 

KATOOM was almost right... they're M12 X 1.5. The holes (4) in the stock banjos are ~.125&quot;

 

12mm x 1.5, not NPT thread. Been there, done that.<br>Just agreeing with everyone else. :<br><br>Chris

 

Just rember one thing your whole fuel system is only as big as the smallest hole . from a engineering point of view.<br> in other words ,is dose not help to increase the size if you leave just one item small or stock.

As well as reduced inner Diam on the sweeps.
