What about the injector return lines? Is anyone using non-standard tubing there? The regular braided line only seems to last about a year on my cars with the new diesel formulation. I know someone has mentioned small engine fuel hose in the past as an option. What size? I ordered some injector return line from an online supplier (it's a house in Arizona) and I just got rubber vacuum line which is cross listed as injector return line.

Vinyl tubing(home depot) or Tygon tubing (order online) should work A-OK

i used fluoroelastomer(sp?) on the return lines because its biodiesel rated... it works fine.

i also have some clear line running from the last return line to the filter housing. it's for lawnmowers/small engines. i found it at oreilly in a box on the shelf in that small engine area. its been on there for 6 months and it still looks fine. i believe its tygon.

More Notes: from a parts place this info next to the Stock Fuel Return Line: Fuel Hose/Line; 3.2mm ID x 1.9mm;
According to this site: Convert inches to mm - Conversion of Measurement Units
1/8"= 0.125"=3.175mm
So 1/8" ID Hose is actually a little tighter than the 3.5mm stock Hose.

Tygon, urathane and vitron are all diesel rated.

Vinyl is not rated for any fuel.

Is it worth a buck a foot to chance your vehicle becoming a rolling BBQ ?
