Hi group, I have a 2000 model Mainship 430 ( Grand Time ) which has two saddle tanks with a cross over ,each holding approximately 250 gallons. Each time I fill either the starboard or port tank I must fill extremely slow to avoid any spillage from the tank vents mounted on the outer side of the hull. Last month while traveling from Floirda to Va with another 430 (Southern Charm) . We had a couple of oppurtunities to fill at the same marinas and the slow fill rate question came up. He stated he also has the same issue , and needs to fill very slowly to avoid the vents from spilling over. The vents would appear to be clear of blockage , and I have tried to take the cap off both tanks at filling . I have put the hose in as far as possible and have held it back as far as possible. Do any others have this slow fill rate? How did you address it? At what rate can you fill you boat without vent spills? At the Beaufort , N C docks the dock hand set the pump at the slowest flow . Which he said was for Sail Boats and I was unable to hold that rate. Not sure what the rate was but I could barely pull the trigger on that handle. I am not so much in a hurry to fill up , but it often ties the pump up for a long while other wait. Any comments? Lynn Grand Time

i have the same problem, too fast and i'd get a little spillage out of the vents. since both fillers are together and right above the vents out the ER, I added pair of 3 way valves connected to a tee and a few ft of clear hose. when refuelling i switch the valves, pass the clear hose tru the ER vent and put it into the filler. i don't spill single drop anymore... pascal ----- Original Message ----- From: <DLLUV@aol.com> > Hi group, > I have a 2000 model Mainship 430 ( Grand Time ) which has two saddle tanks > with a cross over ,each holding approximately 250 gallons. > > Each time I fill either the starboard or port tank I must fill extremely slow > to avoid any spillage from the tank vents mounted on the outer side of the > hull.

A second reason for fuel spitting out the vents is that the fuel fill rate is higher than the vents are designed to handle, along with the vents being set too low to the top of the tanks. Solution is on my web page. Click on Repairs, then Fuel Vent. For a picture of the vent reservoir , cl. on pics of CCRIDER, and go to page two. I made it of aluminum but it is easy to do in plastic water pipe fittings that are glued together. Of course I put a screen over the goose neck vent. It is great. No clogged vents and no fuel spitting overboard. A simple and easily doable solution. CCC Charles C. Jr., and Pat Culotta M/V CCRIDER Patterson, La. http://www.geocities.com/charlesculotta
