I know there has been a fair amount of discussion in the past as to

location to mount the Andair, whether or not to use an extension.

Being at that point in my build, it appears to me that mounting the

valve flush with the top of the panel avoids the extension issue,

requires a few extra bends in fuel lines to make room for heater duct,

and puts heat right under the valve. On the other hand, it also seems

to put a large upward loop in the fuel circuit. It appears to me, not

having gone beyond this point and not knowing other pitfalls, that

using the full 12" extension would minimize the uphill direction of

fuel flow, allow heater duct to go above the valve and fuel lines,

while shortening the fuel lines between the entry to the tunnel and

the fuel filter. I have the newer "B" variety valve, so no

customization needed on the extension. What have others experienced in

delay time ordering direct from Andair? Wonder why Van's doesn't offer

the extension.  I note that Van's valve mount is something like .060

aluminum. I have some .040 that would be handy to use, probably with

alu. angle, which seems like it ought to be plenty strong, or just

move Van's mount lower in the tunnel and make a plate to go on top of

it to accommodate the Andair configuration.

We ordered a few things from Andair about 6 months ago including an extension kit.  I was pleasantly surprised by how quickly they arrived.  I don't think it was much more than a week.



I ended up just emailing my order because the web site order choked when I tried to check out.  I got a response right away.

I've ordered from them several times lately on their web site and always got the stuff in  less than a week. It used to be longer and the web ordering was terrible. My experience now has been seamless.
