Black Bladder bag for Diesel?

[saltybob2]

We just bought a "project boat" Cal 34 Mark III. The PO used a Black Bladder bag for the Diesel and the holding tank. I'm not sure I trust 'em. Anyone had personal experience withn them on their Cal?

We recently bought a CAL 31 and also have a black bladder bag for the holding tank. Too small; located under the forward part of the v-berth. We're trying to find a good spot for a rigid tank. No leaks though with the bladder tank. Hard to flush well though. Juli

I have the same boat and am in the process of considering holding tank location and material type, etc. My old rubber one leaked. It is a small space, and a replacement rubber tank is almost as much as a new aluminum one. From what I have read, I would prefer aluminum, as my experience (smell) matches the cons of that installation(rubber). Plastic is another option, although I have not seen existing plastic tanks that would fit that space? A remote possibility, would be the dual-option aspect of aluminum, if there were access ports, and I was willing to, or needed to, go down that road.
Any thoughts or ideas on this appreciated.

After posting this question, I checked with another mechanic. He said he's seen the industrial rubber fuel tanks, full of fuel, dropped by heilcopters onto the ground without breaking. Just the same, I've decided to replace mine with aluminium as soon as the boat dollar come in.

A Black Adder bag? I am certain I wouldn't trust one from Seasons I or II
