Fuel Lines

[SHobbs]

While at work this morning I had to start up a locomotive so we could use it to move some boxcars around. I found some hoses connected to various parts with AN fitings on each end, not sure what they are made of but they had a blue fabric or some kind of material covering the outside. Anyone know where I could find these? I would like to see if they could be used for fuel lines.



Thanks,

Scott

Were the fittings AN or JIC?

I'd be willing to be that they're JIC.

If I want hoses fittings or gauges I go to an Industrial, and Professional Truck type store, as they are a good source of information, plus their customers cannot afford failures, or experiment.

Matt,

They looked similar to what I have on my truck thats why I am thinking they are AN, could be JIC.

AN = 37° seat with fittings usually made from aluminum with standard NF threads
JIC = 37° seat with fittings usually made from steel with standard NF threads

for most things, they are completely interchangeable.

the hoses at the start station of the locomotive [gm/emd i am assuming] are either dayco, gates or eaton/aeroquip depending on who made them. the original emd stuff seems to be mostly aeroquip [blue covering] the equal in dayco is black covering. the gates equal is in a green covering. those are the standard colors they come in for those brands, but other colors are avalable too. .

i know at the diesel shop where i use to work [on the locomotives] we use to stock the aeroquip hose, but then started stocking the gates stuff. same quality, different price [when you buy in spools, a little price change per foot makes a big deal]

the gates stuff we stock is C5D hose along with their field serviceable fittings in jic and npt for the hose in -6 to -12. we do have some larger stuff sometimes for the ge diesel engines [-24 or -32]

the fittings between the field serviceable hoses from brand to brand seem to interchange well from one brands hose to other brands fitting.

they are a little different though. the field serviceable hose is smaller in the ID than the -dash would indicate. a -8 field serviceable hose is 13/32" id iirc

Nick,



This was on a GP38 and the hoses were connected to the assembly where the low water button is located. There are other places where they use them too. I thought it would make a good fuel line if they are made for it.

there are a few different grades of the hoses, and many are rated for fuel & oil. great stuff to work with as you can make up a hose to replace a broken one in very short time. i have used the c5d gates hose to make up new fuel lines for older engines [gp9's] when changing the style of fuel transfer pump.

my fuel system once i get around to installing it will be made from the aeroquip hose in -8 that is like on the locomotives. i got a stellar deal on some hose ends from the shop that stocks our shop. i do have a few "AN" fittings i am going to mix in with the jic's [m10 to -8 for walbro pump], but it will work for me
