MD6A and Fuel Tank Removal

Mar 27, 2002

The MD6A in my Vega is completely disconnected except for the
Propshaft. I am hoping to pull the engine out this weekend. If
anyone is interested in the engine or any of its parts please let me
know.

I would like to know the steps required to remove the fuel tank if
anyone can help. Thanks.

Hi David,

Having removed Naim's (keel mounted) last year, here are my thoughts. Empty
the tank completely; remove any keel mounted batteries; disconnect all hoses
from the tank top plate arrangement (3 I think) this can be a fiddle and needs
patience; the tank is not secured in any way so just heave up the fwd end and
work it out into the cabin. There is little point in undoing the ring of bolts
around the top of the tank until the tank is out.
The tank is a tight fit and requires a bit of huffing and puffing to achieve
the desired effect. Do not foget to lift out the tank support and clean our
the void. Mine was full of rubbish

Regard Colin

Gents:

I may be able to add a bit of information to help: I had my MD6A injection
pump rebuilt this summer. The cost for just that at a highly respected place in
Deep River, CT was $436.00. Almost all was labor. For what it's worth, that
was not the cause of the problem that I was having, as the problem persists.
I've been told that these injection pumps almost never fail.

As to removal of the fuel tank, assuming it is the plastic tank in the
bilge, involves: [1] remove all visible connections from top of the tank (NOT the 8
- or so small stainless bolts and nuts that are visible holding the fuel tank
cover plate on), and [2] remove the fuel hose from the fill connection by
crawling inside the port cockpit storage locker. Also, [3] remove the boat
battery if it limits space at fwd area above bilge where tank must pass. You're now
ready to simply lift and 'wiggle' tank out of the bilge, trailing the fuel
fill hose behind it. I did this a few years ago and must do it again. Only really
practical way to clean it thoroughly. I will be doing it again this fall /
spring again.

One more thing: I understand this cannot be done while the boat is in the
water, due to the "squeezing" of the tank from water pressure on sides of the
keel.

Good Luck..........Ed Davis......aka saylered@... Vesper; Vega #

Let me add my 2 cents:

1) Much easier to do this with 2 people - one guiding and pushing on
the filler hose while the other is pulling the tank out.

2) You can pull the tank with the boat in the water. I did it in 95
when I had an injection pump problem.

3) Tie the 3 lines together which you removed from the tank with a
long piece of thin rope or wire. That way you can tie them up out of
the way for removal and installation of the tank.
