Source of nylon injection pump hoses
 

Are those clear (now brown) hard hoses on the banjos nylon? Anyone tried replacing just the lines by re-using the banjo fittings? Are they also called Tecalon? What size are they and where can I get some?

I got mine from the dealer when I had the IP off my SDL.

Some info here:

We replaced them with new lines from the dealer as well.

Those lines look to me like they're shrunk onto the fittings -- related to heat-shrinkable insulation? No one here has come up with a DIY solution so we're all buying from the dealer, AFAIK. They're not that expensive, I just ordered one for about $10, but I'd like to be able to reuse the fittings too. It would be environmentally friendlier and less expensive to boot.

At least they don't melt in biodiesel.

I have a question about return hoses
 

does anyone know how well Urethane hose will stand up to use as return lines from the IP on an 85-87 300 diesel? the hose is rated good for biodiesel but i'm not sure if there is any pressure in those lines that would cause a burst. anyone?

I had to replace one of my hard lines that broke and I just used nylon air brake hose. I cut the old hose from the barbed fitting, being careful not to damage the barbs. I heated up some biodiesel (oil will work too) in a breaker to about 150*C then put the barbed fitting into it for about a min. I used some welding gloves to hold the fitting and just pushed on the nylon air brake hose. Once everything was cool it was solid as a rock and has been working for over 20k now with no issues. I can;t recall what the air brake line cost but I know it was very cheap and I can get it anytime I need. The only thing it that its not clear.

Thanks for the replies. $10 to $15 for a new clear hose with fittings is a bargain. However, I need to re-plumb the lift pump to put the filter on the suction side (of the lift pump, instead of the pressure side), so I need to custom make my own hard nylon lines. I already figured out how to get the lines on the banjo barb (using the old lines that I cut off). The trick is to heat both the banjo fitting and just the portion of the hose that will slip over the barb in hot water, then quickly push the nylon hose onto the barb and strike the banjo against a block of wood to force it fully onto the barb.

The hot biodiesel or oil is a good idea. You can heat oil to be hotter than boiling water.

When I did a filter mode I broke one of my plastic hoses (it needed to be longer). I replaced that hose and the one between the Secondary Filter and the Fuel supply pump with 1/4" black Fuel Hose and hose clamps. Not as neat as the plastic but functional.
To remove them I heated the ends on the barb with a butane lighter and pulled.

The fuel line on the top of the spin on filter the return and cigar hose attach to is $20 plus from the dealer.

I have an up date here, was checking my reciepts for this fuel line,
it was $37.50 plus tax. $40.50 :eek: :eek: :eek:. Part# 615 070 5632.
