Is 1/2 inch copper the thing to use for diesel generator fuel lines? |

Luis, if you have a bus, look at what they used, MCI uses Copper. Gee I wonder why, cheaper? won't be eaten up by any Diesel or the components put into it? To each his own, I used copper. |

copper will dissapate heat....rubber won't.... heat causes condensation... copper is the better choice.... |

Copper has to be installed and supported correctly as it work hardens which makes it prone to cracking.
Not saying don't use it, saying use it correctly!

I used 3/8" I.D. braided rubber fuel hose from NAPA with press-on brass fittings, that have a clamp applied after they are pushed on. About 10 feet of hose to the genset, and same for the return line. Ty-Wraps to keep them properly supported and neat. Very tough, and difficult to damage by impact or abrasion. I took a pair of pliers and a hammer to a piece to test it before I decided to use it. Lot's easier than copper to install, and about the same cost. Cheers...JJ |

Thanks for the input. I've actually seen both used, copper and braided rubber tubing, just picking brains out there to see why one would be favored over the other. |

Don't know about that Two Dogs. The 4104 was made with what seems to be miles of copper tubing. Water, air, fuel. Lasted 50 years & looks like it'll last another. I am certain that if rubber had been used, the buses would have been in the junkyard decades ago. The braided rubber in the engine area has been replaced at least twice on my 4104.
But I'll buy that IMPROPERLY APPLIED copper will break. You definitely need rubber sections at any place that sees movement.

FWIW, Freightliner, and International are using Parflex (air brake plastic tubing) on their bus chassis. Seems like a great idea to me.

Isn't Parflex a good thing to use for your water lines as well? My father-in-law had a trucking company and that's what he suggested. He said they won't break if they freeze. |

I would be careful in using copper as ther are many types and alloys available. Make SURE you have the correct type for your application. I'm sure GMC didn't get theirs from a local plumbing supply house.
My old IHC truck manual refered to 'double walled copper' as the only acceptable tubing to use for the air and fuel system. The Parflex is much easier to install and service tho.
As far as Parflex goes, if it's not rated for drinking water use, it may add flavor to your drink. |
