T&T: Fuel Hose

[Steve Sipe]

We've suspended our cruising for a month or so to do some family 
business and we'll be doing some maintenance and possibly an upgrade or 
two to Maerin.

One of the things on my list is the 3/4" crossover hose between the 
tanks. It is the OEM hose, and is showing signs of cracking. I want to 
be proactive with this item.

The hose that was used on some of the fuel lines on board is Parker with 
push-lok fittings, I plan to replace the rubber hose on the crossover 
line with a similar push-lok hose, but from what I can find on the 
Parker website, the hose is not rated A2. Perhaps the SAE rating exceeds 
the A2, but I am unsure how all the ratings correlate between the 
different agencies, e.g. USCG, ABYC, UL, SAE, etc.

So I have a multiple question...

   1. What Parker hose can I use that won't raise a flag when the next
      survey is done?
   2. Is not the A2 rating for fuel fill & vent? This is not a fill
      line, it is essentially a fuel line in that it is filled with fuel.

The best I can figure, the 821FR hose will work with the push-lok 
fittings, and *should* meet USCG & ABYC standards for how I intend to 
apply it.

I'm sure someone on the list has some experience with the Parker line 
and applying it for marine use, I want to be sure I'm well within the 
spec before I do anything with it.
