I have the standard $30 flip fuel fills and venting... How do i vent my tanks if i wanted to. My tanks have plenty of plugged holes in the top of them but what do i need to do so that i dont get fuel pooring everywhere..
You can buy a new set of vented caps. Another fix I have seen is drilling a small hole in the cap. There may be a way to retrofit your caps with a legit setup.
Or, google fuel tank vents. If possible I would vent the tanks outside the boat. No need to vent into the hull and risk potential fire. Pretty sure you can run the vent with some hose to a through hull fitting. Caps are a lot easier.
I am machining ones right now. I do not like the ones on the market. They look as if they will "injest" water when mounted straight up. I am trying to make them so the water will have a harder time getting into the external vents.
The ones like these. I do not want to drill a hole in the side of the boat. No way. So if you mount these above the tanks near the fillers then they would be "straight up" on a horizontal surface of the boat. That is what I mean.
Shaun one thing to do is put a loop or two in the vent hose this helps on the full tank sloshout blues! WT
I've done this with both rubber hose and also 3/8" SS tubing, a couple loops then run the vertical section underneath the gunnel. I never had any fuel inside the boat or noticed any fumes. Brendelljet makes a good point that the fumes could be dangerous venting inside the boat. However, with a flat where everything is out in the open and a LOT of wind going past the engine, I never had an issue.
Do this with the through hull. Venting inside the hull is dangerous.
Or, get a set of venting caps from rex. I ran 800 HP with a set of Rexies billet caps and had no probsl on 2 15 gallon imco tanks.
Which ones are you talking about? My fliptops are from rex.
Loops would work i guess, but it's possible of having fuel stuck in one of the loops but i guess it would be sucked back in. I would dump the vent out a dump but i dont like the idea of there being a direct lines from the water to my fuel.
I'm not sure venting is really my problem, i pulled the fuel line and ran the pump for a good 30 seconds pooring fuel into a can and it was pumping plenty of fuel and didnt look to have any problem. Course thats flow and not pressure, i suppose if the tank had a vacum it could cause the fuel pressure to drop and not push fuel fast enough into the bowls?
No, i understand why i need to vent the tanks if the flips i have now are not adaquite but what i'm getting at is that the pump doesnt seam to be having a issue pumping a ton of fuel, way more than i would be using at WOT for a 30+ seconds with out seeing a noticable change in the flow... What i was also getting at is that flow looked good but maybe pressure is what was being affected.
I wont be at elsinore this weekend, i'm heading up to sandbar resort (formally known as redrock) in parker this weekend.
I'm going to set the floats correctly before i go adding any extra venting and run it this weekend and see what happens.
Brendellajet, Those fuel fills look pretty cool but i dont think they will work for me. Whomever drilled the holes for my gas tanks did it way too close to the lip that comes up on the hull. I had to shave alittle off the bottom of the flip tops on one side to get them to sit flat and not have a huge gap.
