00 fuel line and possible gas tank drop?

hi I have a fuel line leak by the gas tank on my sisters truck

there are 4 lines running what ones are fuel 3 of them as I figured maybe only 2 send and return and 1 be the brake line

either way I cant see much I guess it has a cover

I wanna run new lines can I do this without dropping the tank it seems so tight as I cant get high enough off ground right now

but I wanna run new lines and are those 3 fuel lines then

bolts are too rusted so I cant drop the tank cant use torch as gas is around
it leaks from one of the hoses up above the tank.... 2 lines I see at the fuel pump don't know where the third one went? but cant really reach that either ... any tricks probably taking the box off easier lol

is there a special tool to unhook the 2 fuel hoses those plastic connections I usually squeeze them on a GM car and I can pull off or use a screw driver to pry but since I cant get behind it.. and I really don't wanna drop the fuel tank just to hook on those 2 hoses and run new lines to the other quick connectors and then figure that 3rd hose

i wonder if people drunk when they build these as this is ridiculus spot put the fuel pump hoses on the back of the tank so nice and easy to access frig

if you can't soak the tank bolts and get them loose that way you might have to remove the bed to get access to the clips to remove the lines. it will have a pressure and return line and at least 1 vapor vent hose. try something like pb blaster or sili-kroil and let them soak for a day or two

oh ok i just picked up these round clip pullers from my local parts store ill try it in couple days gotta finish doing the brake lines on this truck never seen a shared back brake line usually i see 4 brake lines not 3


but i don't have pb blaster ran out i guess wd40 not strong enough
dunno what silli kroll is

isn't the only way to soak these bolts is if you could flip the truck upside down or back the truck into a PB blaster bath tank lol i can spray them that's about it

don't know why they made it so awkward

ok so if the 3rd one goes to a vent under the hood what is that black box behind the gas tank tail gate side its a rectangle box

i said at least one vapor line, probably has another one or two that go to that tank along with one from the engine compartment. if you do get a can of pb blaster type stuff you can buy extended hoses that fit into cap to spray into places the can won't fit if the top of the bolt is exposed but hard to get to

oh ok i didn't know there was multiple vent lines that's all so what is that rectangle box then

i only used to GM cars and Dodge trucks so they only ever had 3 lines 2 for fuel and the other for emission gas vapor what not..

but ok ill give that a shot i just finished doing all new brake lines so ill spray and let it sit a few days

thats a charcoal canister that the gas vapors are supposed to go through to filter the bad stuff out

oh ok thanks

so ya i sprayed the bolts with wd40 that's all i have at moment so let it sit for a few days and ill try as i don't think i can reach in that gap area with my hand and these plastic fuel line remover tools and pull them down

they sure put it in an awkward place i must say

thanks for the help so far i appreciate it

wd40 isn't really a rust dissolver but guess uts better than nothing

its all i got moment till i can make it to store store is 50 min drive away

and i heard power steering fluid or tranny fluid is a good rust remover is that true and whats in it that does it


and if wd40 not a good rust dissolver,, then what good is then for
