Today I filled up to 3/4 tank and hit the lake for the second time in my new to me 95 prostar. Upon arriving back home I noticed some yellow streaking down the back of my boat right beneath the chrome fuel vent.

Any one have a fix for this???

The tank wasn't anywhere near overfilled. I really don't want fuel dripping into the lake and staining my gel coat. I searched and found that Skidim might sell something to help prevent this but I can't find anything on there site. Anyone have a link?

Thanks!

I have only had that happen after filling up, then the fuel expanding due to warm weather causing it to leak out the vent. It's surprising how much fuel can expand. I'm very cautious now about how much I fill it up. If there is a different fix for that problem I'll be interested also.

I don't think it should be that sensitive .... My ol 93 did it a few times, but I had really filled,it up.

I read somewhere about a loop in the vent tube that needs to be present maybe someone can chime in ... Good luck.

That makes sense, but I can't imagine it expanding enough from 3/4 of tank to overfilled. I also filled up at the peak temp of the day which was only about 70 degrees...it was overcast all day too.

Mine only spills out the vent when I fill to the very top. '95 prostar - only happened one on a warm day.

I have the same problem on my '96. The curvy and hilly roads I tow on causes the fuel to slosh around quite a bit. I bought a longer vent line and looped it back around the deck fill and then on to the vent. It helped, but I still get fuel sloshing out if I am close to full. Always on a fresh wax job.

This is an option. (http://www.amazon.com/gp/product/B0000AZ7PE/ref=ox_sc_act_title_2?ie=UTF8&m=ATVPDKIKX0DER) I don't know if it will work or not, but I guess I will give one a try between the tank and the loop at the deck fill.

I have something like this on the vent line of my S & S. It seems to help.

My 96 has about a 6" loop in the vent line, and only spills if it's very full, which it rarely is.

I think I'll buy some longer vent hose and try looping it around something and then connecting it to the vent. Does anyone know what diameter hose I will need? Looks like 5/8"?

If that doesn't solve the problem I'll look into getting a value like table rocker and tph have suggested.

5/8" is the size and it needs to be USCG approved - Type 1 I think.

I used took a conduit clamp and put it on the back of one of the fuel deck fill bolts. I ran the vent hose up through there and then on through the normal conduits and to the vent.

Perfect, thanks for the info! Hopefully this solves my problem. Right not the vent tube runs straight to from the tank to the vent.

The "normal conduits" I referred to are pieces of pvc that are glassed into the front edge of the rear deck. That is the way it is on my '96 205 anyway.
