Title: Is neoprene hose from like Home Depot diesel fuel friendly?
Post by: SR Heer on June 29, 2011, 06:39:04 pm

I am wanting to replace the fuel lines on AAZ motor and in wanting to keep with clear tubing so as watch for air bubbles I was wondering if one could well use neoprene hose or tubing from Home Depot - or does any one have any other good suggestions for replacing clear fuel line hose?

Yes, that will work for fuel.

my suggestion, go to the nearest motorcycle shop, and buy motorcycle fuel line.. its made for fuel, and is clear..

either that, or go with tygon tubing.. it will stand up to ANYTHING..

Home Depot has it eh? Does it stay pliable and stuff after it sees fuel and such? Or does it harden up quickly?

IF it's the clear tubing I'm thinking of it doesn't work the best..   For the fuel supply it can and does collapse under the suction of the pump..  IT doesn't withstand a lot of heat which will make it collapse faster..  And it does get hard and brittle with time..  As Kevin said, motorcycle fuel line or tygon would be better options...

I vote motorcycle fuel lline,.. still flexy after years of use.
 Even in very cold weather.
 And fairly cheap.
 Blue urethane from the Honda shop.

Long story short, I had to replace everything on my jetta after getting it home.  Multiple breaches and deleted the water seperator.

I went with cheaper polyethelene as my hard lines in the stock clips.  Then I installed a barb fitting and junctioned in the rear to the gas tank sender with some nice clear brown thick walled fuel safe hose from mccaster carr.  This stuff is expensive but I also used it to junction the rails in the engine bay to the fuel filter, filter to pump, pump to return line and the return lines.  Not that much footage needed.

I like it very much, almost pushing a year.  It is thicker walled than all that other thinner stuff you can find at the local hardware store or ebay.  Also through all the work and tweaking I have done, every time I have been able to pry it off the barbs with a screwdriver then put it all back together without cutting that section off!  That is after allot of heat cycles!  I left extra in each area just in case though.

I love being able to check for bubbles, etc.!
