Hello Jeff;
Your saw is listed here:
McCulloch MTD
Chainsaws 32cc-35cc-38cc Anti-Vibe
The IPL (exploded parts list) for your saw is the only detail for fuel line routing and it is sketchy at best; components are listed but may be on different illustrations. The primer is displayed but not listed, and there is no part number. Before you get to deep please contact OrderTree.

Use the IPL as a guide for disassembly/reassembly.
This is typical routing and a couple of hints.

OMs for McCulloch are tough. harder than replacing the fuel line. Have your saw within easy reach they will want the serial number and a few other things.
Operators Manuals: are much more difficult. I have dialed this number many times (Contact Us - All McCulloch Products 1 (800) 521-8559) and have yet to get a satisfactory response. Please try this! If enough of us try they will fix it! If unsuccessful with McCulloch try here:
Beg for manuals thread (ArboristSite - free to join). Please use the search function first, it has probably been asked and answered.

SOURCE: Poulan chainsaw primer bulb replacement

Hello Jay;
The primer listed for your saw and sold by Poulan does not include hoses (do an Internet search for the part number below, there are photos). Hoses are sold separately and are 2 different sizes. You can cap the carburetor to primer connection at the carburetor and your saw will run as all chainsaws did before the addition of the air purge system.

An example of a Poulan "2375LE Gas saw Type 2" follows (may not be your saw):
The IPL (exploded parts list) for your saw is the only detail for fuel line routing and it is sketchy at best; components are listed but may be on different illustrations.

See the "Engine Assembly" print; item 4; pn 530047213.
Small hose in the tank with a filter on the end (long enough to reach all corners as the saw is moved) the opposite end connects to the carburetor.
A second small hose connects between the second carburetor fitting and the suction side of the primer.
A large hose connects between the pressure side of the primer and fuel tank (return).
I suggest you replace ALL hoses. Do you change tires on at a time?

Plumb the system EXACTLY as the diagram shows. If it will not run you have the 2 connections on the carburetor reversed. It might make sense to leave them long enough to swap until everything is working.
A typical fuel system and a couple of suggestions can be found here:

If your saw is not a Type 2 or an LE (code for Wild Thing) you can find the correct IPL here:
Poulan.com
http://www.ordertree.com/modelinfo/POULAN-WEED-EATER/75.59.html
The dash number of your serial number is the type.
