Here is Lucky Mike's original "recipe" from that other thread. Does anybody know of somebody who has actually used this? Seems like more work that getting a hose over the #$$%%%$$# barb. Are there any other methods of getting the hose over the barb besides cautious patience and gentle pushing?
Here's some reading on doing it yourself: https://www.benzworld.org/forums/w12...uel-lines.html
If you want to do it right, either buy from the dealer or, from a very experienced friend of mine:
"The true and tried method is an old one passed along over the years, since this technique is used in manufacturing facilities and usually not found at the mechanics bench. The way to do it is as follows:
-- Get ghee, avocado or safflower oil at the grocery stores, which have a burn or smoke point near 500F.
-- Place the oil in a pot with high walls and fill to half its height.
-- Make sure that the half point fill on the pot is greater than the hose to fitting mating area. In other words, if the hose needs to slip onto the barb 1.5 inches, then the half point on the pot better be about 2 inches. You don't want to heat more hose or less hose than necessary.
-- Get a turkey or candy sugar thermometer that goes to 250 or 300 deg F and insert in the oil avoiding touching the bottom and walls.
-- Heat the oil to 212 F and insert a piece of hose to be used in the final job, but not the final one.
-- Hold the hose off the bottom of the pan and in the middle of the oil pool if possible for at least 2 minutes.
-- Remove the hose, wipe with rag clean of oil and try to insert into barb.
-- If inner core is still stiff, increase the temperature of the oil to 250F and so on until the inner core is soft and pliable like silicone hoses.
-- Each nylon hose core manufacturer uses different formulations of Nylon (like Nylon 6, 11, 12, 16) and each has a different softening temp."
