Where to buy fuel line nuts?

Pascal · Post by **Pascal** » Tue Jul 06, 2010 9:43 pm

Hi guys,

I am trying to connect the fuel lines of my 590e. They are the same as the 4 cylinder.
Does anybody knows the measurements of the fuel line nuts?
Are they 1/4? Or 1/2? UNF?

Are the airpipes between the vacuumpump and air inlet 5/16?

Does anybody knows if I can order them with the NH-dealer? Does anybody has a NH-number perhaps?

I hope you can help me, so I can try to connect the fuel lines this weekend.
Thank you in advance!

Try Agriline, maybe under acessories and Cotswold Vintage Tractors

Count the turns per inch
Measure the width of the thread on the bolt
Measure the thread pitch if you can

The first 2 should be enough to work out what type of thread it is. just google some charts on threads and match the value. Assuming the thread isn't tiny, you should be able to do it with a ruler
