Slow draining fuel filler
I replaced my rusted tank with a plastic one and increased the total capacity from 60 gal to 100gal. My filler neck is 2'' and I used 6-7ft of 2'' hose to connect to the new tank. At the tank connection it necks down to 1.5 using a reducer. I have a 3/4'' vent line going back up to the top of the filler neck, the vent line connection on the tank may be a little small as I think is has a couple of 1/4'' holes in the tank part. I tried to fill the new tank yesterday and had slow drainage of the fuel form the filler neck, it took around 5-6 mins to get 10 gallons into the tank.. There is only around 6 inch drop from the filler neck to the opening the tank. Is there a certain slope that is needed or does the vent line at the tank need to be drilled out larger. Any help would be appreciated.
