Well been having trouble loosing prime. Well took my stepson to Butte MT about 169 mi away shut truck off wouldn't start got out to pump the primer wouldn't start but could here and hissing sound. Looked around and finally found the problem. The inner cooler tube had rubbed thur the metal tube feeding the fuel filter housing. I had some electrical tape wrapped it around the leak got it started and drove it home. Went out today and got a longer pice of hose and pushed it over as far as i could to cover the hole and got it working fine. will find out if it works good in the morning when it is time to go to work.
