hey guys, while doing oil change yesterday, I notice 1/2 hose from filter to vp-44 has some cracks on the outer hose. i have the vulcan fitting, pump near tank. the hose i got from a freind that does diesel work, only 10,500 miles on this hose. name on hose is( lockmaster). has anyone had this problem, or it may be the heat causing it to happen,what's a good hose to go with if you had no problem. I hate to have to change every 10,000 miles. any suggetion
