JD 4430 injector line problem

lemroy · Sep 16, 2014

I have trouble with the rubber tees that connect fuel line to injectors. Is there an after mkt syst em to replace these tees. Roy

John Deere has a kit to replace those with brass fitings and lines. Maybe TX Jim will chime in here. I replaced those on a 4440 2 years ago.

When you replace boots are you replacing ALL BOOTS at the same time?
Here's the later style leak-off line for a 4440.
RE27786 Fuel Line - LINE,FUEL LEAK-OFF ASSEMBLY ADD 143.34 USD

Where can I order that type setup for a JD 4430?
Thanks. ROY

my 4430 has steel tees.I went to Deere years back to buy a replacement line. It was way over $100. I replaced the plastic tube with rubber chain saw fuel line.

He must have a '77 or else wouldn't have that type return line.

I just looked up a return line for a 4440 without boots but I'm not 100% sure it will fit a 4430. Please read Mark-Ia post.
Thanks,Jim

KDEL and KDL nozzles on 4430. If I don't have them backwards KDL was first w/return lines on top.
KDEL had return lines on side of nozzle. Was used last year of 4430.
Early 4440 had same returns as late 4430. Next had one line w/holes and a different plastic tee maybe molded to line. Last had lines w/metal tees and should fit last year 4430.

After further research I think return line(RE27786) will fit but will also require 6 fittings(R87082) to attach line to injectors. Roy's 4430 engine SN should be above > 445570- to utilize the newer style line

Thanks all you techs. I will see if our local JD dealer can get these. Roy

Deere wants you to replace those fittings anyway on all. They use orings against injector instead of soft metal washer.
