Question on doing a Fuel leak fix

Yup. Except I only have a shut off valve on the tank I don’t use! Go figure. I thought about taking the line on top and hooking it straight to the passenger side where it fits to the spiltter

 

Ok thanks. Do you think when I undo the fuel line from the splitter that fuel will come rushing out?

 

I appreciate your responses. So, but, if I damage the fuel line and need to replace it, it will leak for sure I imagine? - if I have to put a new fuel fuel line in at the bottom of the tank right

 

Well I got started on it today. Went to loosen the driver side tank line at the ball valve on the splitter. Noticed the ball valve itself was loose. So I tighten the ball valve back into the splitter another round or two until it bottomed out. Seemed at first to stop the seeping, but I’d still sweating out somehow, but not at the threads now like it was. I notice now, the middle line going to the motor is sweating too. Not enough to drip but enough to sweat and gunk up a bit. Which is probably OOS right? For any diesel leak?

So I need to do something here. Thinking about just getting a new splitter with new fittings, attach all the fitting with tape nice and tight before I mount it. But the only thing is; when I opened the ball valve to finish tightening it, it drained fuel out at a steady little stream, more than a drip but less than gushing out. I let it drain for about 2 minutes and it kept going. Wonder if it’s from the fuel in the line to the motor?

So I’m trying to figure out which lines to take off first when I put the new one on? I have a davco filter housing, I wonder if taking the top off of that will help, like when you drain the fuel to change the filter.

 

Ten4. We had a peterbilt once that I was running low on diesel to make it to a discounted fuel stop. I put 30 or so gallons in to get me the extra 75 miles or so and I ran out of fuel on i20 in Dallas lol. One tank took from the other.

So at that time it made more sense to just run on one tank instead figuring what the issue was. from then on it became like a habit and I kept doing it like that ‘kind of thing.
