Stay away from Jegs and Summit "Braided" Hose. it is still push loc and only 300 psi resistant, with no wire insulation or teflon. 500* is an easily reachable temp when these lines are a foot from a 1500+ degree exhaust manifold. Just because people use it doesnt mean it could not pose a problem down the road, either. There is a reason why we will not sell a fuel system containing sub-par parts and only use 5800 psi, teflon insulated hydraulic houserated at over 1400*. If a push loc line were to ever melt near an exhaust manifold- and hot diesel at 50-100 psi starts gushing... you can imagine the end result. I can also make you custom length lines with any fitting you need. Let me know if we can help.
