That's right Tony, I'll see what goggle produces, again. I've bumbled into the flightboy's sites on the tank issue a number of times. They are good on builtin tanks, sculpting great aerodynamic shapes, and keeping things light. Tho damn hard to understand what the hell they're talking about sometimes!

It would be possible to make your own studded rings and plates, but for me, anyway, very time consuming. It's probably possible to have them sent over from the UK. The inspection hatches, the Henderson, is already expensive, add the cost of shipping etc, and it's bordering on foolish. Yet... Yet, I want to touch one first.

There's probably 100,000 sites on tanks alone, you'ld think you'ld run into one of them that would have them available to the consumer, here. There are stringent regulations about fuel tanks in the US, insurance and liability issues that maybe the cause. There must be a market. In the UK there is!

The famous Henderson Mark IV manual waste pump from Ireland is certainly available here. Assuming that the inspection hatch is the same manufacturer, somebody is missing the boat.

We're so rich in this country, except for you and me, Tony, that when it gets to the point you have to clean out your tanks you just go out and buy a new boat!
