Paranoia about the D3-110 Volvo Penta - diesel bug
Scott SV Tengah
My paranoia about my Volvo D3-110 (rev c) has been kicked back into high gear. I think this applies to anyone with a diesel engine but particularly with the hyper sensitive D3-110.
I know a few A54 owners with failed D3-110 due to water ingress. We've discussed that on another thread. I'll leave that discussion there.
Recently I met a HR46 owner who had to lag behind the World ARC ($$$$!) because of diesel bug issues on his D3-110C. Another HR48 owner had the same issue and in both cases, the engine died and wouldn't start back up. His tank was disgusting, apparently. I've opened my inspection hatches and my tank is nearly pristine. But I am not going to rest on my laurels.
What do you guys do to keep your fuel system clean? Here's my procedure and I hope I can improve on it with your help:
1) Diesel only from places that get high turnover. We aim for duty-free, so they're usually in high demand.
2) Outside of the US and EU, we use the Baja filter. Damn slow at only around 8liters per minute, but you gotta do what you gotta do... That said, I know of a few owners in the EU who have had diesel bug - seems more prevalent with biodiesel.
One idea to reduce filling time (900/8 = nearly two hours!!) is to use the Baja Filter to fill up our spare 20liter jerry can and then inspect the Baja filter. If all is good, just fill up the boat without the filter.
3) I use BioBor JF. I don't know if it's the best, but I found a bottle in the US that was enough to treat 10,000 liters, so that was my decision making criteria.
4) I have 10 micron Racor filters in the water separator filters. I carry 15 filters aboard. Two micron in the Volvo, per spec.
What do you all do to ensure you aren't stricken by the bug?
