fuel line crimped

[ARhine]

the fuel line that runs from the filter to the inj pump is crimped/twisted almost shut right above where it screws into the pump. Looks like somebody overtightened it or something causing the line to twist.



I was trying to decide if there was enough room back there to get the line out and a new one in?





Anybody know if this line is a part I can buy or just have to make one?

I bought mine from Cummins.

The fuel line is easily replaceable, and available from Cummins for around $25. At least that is what I paid last summer for one on Mom's pickup.



THere SHOULD be a tag on the line with the part number- wraps around the line itself. MIGHT (though might not, either) be able to get it from CaseIH, too.

If it is almost completely shut. Definately replace it. A crimped line to the injection pump can cause rapid wear of the pumps internals, high fuel temp, low power. It basically makes the pump work harder with less fuel for lubrication.



Cummins lists the fuel pump supply line as 3918641 (probably superceded so dont be suprised if they give you a different number). However, this should get you started.



Here is a link to the breakdown of the fuel line and fittings. http://www.dieseltruckresource.com/.../cat/500/page/1





Using the numbers assigned to each part, refer back to this so you can see what part number corresponds to each part.



1. 3908988 Tube Fuel Supply



2. 3905351 Seal, Grommet



3. 3918641 Tube Fuel Supply



4. 3905351 Seal, Grommet



5. 3908985 Union, Male 9/16-24 x 9/16-24

Anybody know if it will wiggle out in one pice?



Or do you have to get it taken appart in the middle somehow?



Thanks for the part#s and diagram BTW!
