quanyin I'm on it. There have been a number of helpful replies, and as soon as we get back from our weekend jaunt out to the local islands, I'll give some of them a try. Thanks for sharing your ideas and those of the factory!

fugue40 Got an answer from the factory - explains some things and has a solution for uncured gelcoat. Here goes-
"... Not knowing what the smell is, anything I pose is somewhat of a guess. We have noticed some tacky gel coat in lockers on some of the boats out of California. We believe this to be a wax that was added for the purpose of curing not doing its job properly. We have solved this by switching to a urethane based gel coat designed specifically for bilges and lockers. If you have this issue on your boat, you may consider coating the interior of your lockers with a marine polyurethane paint to seal in the gel coat..."

Every little bit helps....

JohnRPollard I forgot to mention one other point:

Many fuel docks have two speeds of pumps. The high speed pump is for bigger motor boats that take on large volumes of fuel. The low speed pump is for sailboats and smaller runabouts/outboards etc. Always ask for the low-speed pump if there's a choice.

stevemac00 I also had the slow fuel fill. I bought a fuel separator for the vent line but never got it installed (PM me if you want it).

I think the problem was the filler tube did not go to the bottom of the tank. When I bought a new fiberglass tank from PSC it also solved the slow fill with the same lines. The tank was expensive but it was well made and fit without modification.

fugue40 We also have this problem. I've sent this thread to Thumper at the factory now that it appears to be "endemic." We have tried several things that have not worked, including relocating the fuel filter and pump for the genset from here to the lazarette, and was about to do the Peggy Hall "hot rag wrap trick" on the hose to see if that was the issue, followed by the Saran Wrap treatment. Strange that it is only this compartment - the starboard side fuel fill area doesn't do this. Yet, I guess...

About the slow fill - We had the factory install 2 1/2" fuel fill hoses vice the standard 1 1/2" and that has helped immensely. Even if you don't have the 2 1/2" valve at the tank, the larger hose up to the nozzle can alleviate the nozzle's constant auto shutoff the smaller hose causes. For the vent problem, I'm as we speak installing a seacurefill (Google "seacurefill" - Sailnet won't let me post a link!) fitting at each fill. I'm hoping this completely eliminates really slow fill and also any blow back I might get despite the larger hose because, during filling, the vent is directed into the fill alongside the nozzle.

mondofromredondo I wouldn't worry too much about the slow fill.
My PSC 34' is a slow filler as well as a few of my other freinds with PSC's.
If it was a power boat that needed a fill every use I'd be more concerned.
It takes me about 15 minutes to put 35 gallons on my boat. Besides I've done more than my share of waiting for other people at the dock that wanna lolly gag around and go buy chips and beer AFTER they have filled 100 gallons on board.

svHyLyte The length of run of the vent hose is irrelevant so long as it is not obstructed and it makes a vertical loop close to the thru-hull to prevent water accumulation. If your fuel fill is slow, it is likely an obstruction caused by insects--wasps are famous for that. Moving the vent to the side of the boat risks the possibility of water intrusion when one is well heeled.

As for your chemical smell, it may simply be uncured/poorly cured resin. One thing that will help is using activated charcoal to absorb the odors. You can obtain activated charcoal at an Aquarium store fairly inexpensively. Eighteen inch lengths of ladies nylon stockings with knots on each end make convenient containers (fill them shore-side as there will be a cloud of charcoal dust when you do so). Drape these around the hoses and they will absorb the odors very quickly. I have used the foregoing to handle the invariable odors from a holding tank under the foot of a berth in our quarter cabin and the offensive odors are all but gone so long as I replace the charcoal annually.

quanyin Thanks to both of you for the ideas. I am wondering if the slow filling might be due to the long run of the vent. It goes all the way to the stern. Someone suggested creating a new vent to the outside of the hull right below (and outboard) of the fuel fill.

slow fuel fill

My PS 37 also had a very slow fuel fill and if I pushed too hard it would burp fuel out of the deck fill. The fuel vent line had a wasps nest in it that restricted the airflow during filling.I also use a 1 1/4 " pipe screwed into the deck fill that allows a better angle for the fill nozzle as well as preventing seawater from entering the tank while filling from a jerry can at sea.

good luck,

I've thought about replacing the vent and fill hose, but am not sure that would solve the issue.

Also, the fuel tank fills very slowly, often to the frustration of the attendant at the fuel dock, or the crews on other boats waiting for me to finish.

Anyone have suggestions to the cause of the issues?


PS 40 #33, Quan Yin
Is the odor more like a resin smell? I have read reports that on a few PS 40s, the interior gelcoat application did not fully kick and set-up in some places. But I don't recall complaints about odor -- just about the gelcoat having a tacky feel.

As for the slow fuel fill -- there can be different reasons for this. The first thing I'd check to see is if there might be a low point in the fill hose where it dips below the nipple where it's attached on the tank. Other folks have had good luck adding a fuel/air separator on the vent line.

Hopefully some PS 40 owners will chime in.
