Part Number for Return Fuel Line - 400D

My manual is for an "A" type pump, and the return line must be different.

I'm no expert, but think the coil is only for absorbing shocks and vibration.

I actually did use NewTech web site to order the part. The one in the picture is PN 363939R11, and it's coil is turned wrong to fit the tractor. If it was turned 90 degrees into the picture, it would probably fit. I also ordered PN 363151R11, but it was for an "A" pump and also didn't fit.

I have been told by NewTech that there were only 2 pipes made, one for "A" and one for "B", but neither fit my tractor. That's why I'm trying to see if someone else has a similar setup and how the pipe is routed.

Something is really strange about that part (363939R11) I got from NewTech. I talked to them about it and they said they compared it to the other 2 pipes they had, and they were all the same. Maybe that is why those NOS items never sold -- may have been made wrong. The bad thing about it is there is a 25% restock fee for returned items, unless it is a mistake by them.

I looked up the fuel return line in my 400 parts book for the "B" pump and it is 363939R11. The "A" pump is 363151R11. Five years ago I needed one for a 450 Diesel and it was no longer available from CIH. Found a used one. Hope this helps.

I>Link did a parts search and it show both lines in stock, pricey little suckers though!
Good luck

Any suggestions would be appreciated.
