Title: Impulse Line
Post by: Cut4fun . on January 13, 2014, 05:39:40 pm
Trying to save the info in one place for what we are using for impulse lines.  I know there is stihl trimmer fuel line, echo fuel line and dolmar fuel line.  Lets try and get the part numbers etc saved. Maybe the size etc. Any info is good info.

Also any other redneck impulse line materials you have used with good success.

Dolmar 965 452 660 is a one meter length of Viton impulse line as used on Makita-Dolmars. This number does not come up on any particular illustrated parts list. But ultimately from some of the big distributors, when you enter the correct number for the proper length (2 1/2" - 3") impulse line, it will be superseded to this number. It is 3mm X 5.6 mm. It is sort of a reddish brown and has EPA-MSX-FA stamped all along it from one end to the other. The prices I've seen vary from $3 to $11 depending on where you try to buy it.

You get a lot of variation when trying to find Dolmar impulse line. In fact it is downright fuzzy. Here's what I get when I try to order Dolmar 7900 impulse line (65mm), it gets superseded at Edge and Engine who deal with Atlantic Power as a distributor. As you can see, The number stays the same but you get 1 meter . . .

FUEL LINE (1METER), PS-401
Genuine DOLMAR
Item # 965452382

If you enter the first number (965 452 660) I mentioned in Google, you get hits also but not at Edge and Engine. I ordered this number at the local Dolmar dealer who uses Central Power and it came through OK.

When I went to replace the impulse line on this Stihl MS-270 (1128-122-6500), the Dealer didn't show it in the system.  He gave me a foot of hose; thick, black stuff.   The only markings on it are "H235R5 0712/1001 A."   That marking is from one end to the other.  This place is also a Husky Dealer.  I suspect this was Husky hose, possibly 544324906 ? 

Looks and feels like a good hose for the application.

Most of the HVA saws I mess with use 3mm ID 5mm OD line. I think the key is the size and that you cannot squeeze it closed between your fingers and that it MUST BE A REALLY TIGHT FIT ON THE NIPPLES.

I was looking in the MS270 parts list and cannot see anything shown or listed for an impulse line. There is a line (item 23) with the number 1128 122 6500 that I have no clue as to what else it could be?

I get most of my line from eBay.   I have a variety of sizes and I always look for rubber line only.

In an emergency situation, and if the damage is only a tear, clean both sides of the tear. Wrap a few turns of a thin cotton strip about 1/4" wide tightly over the tear, slowly soak the cotton with a few drops of Super Glue.

You can then run the saw while waiting fora new impulse hose
