Does anyone know if I need to drain my gas tank if I'm going to change my fuel filler hose (ie. the hose from the gas tank to the filler neck)?

Thanks!

 

Not unless it is completely full................................

 

It sure will make the job easier though, either that or do like I did and loosen the bed bolts and jack the bed up

 

I put a few bucks of gas in it last night. So the main thing I'm worried about is liquid gas sloshing out, not pressure in the gas tank, correct?

 

Nope, no pressure in the tank.

As has been said - you shouldn't need to drain it if it's not near full. Either lift the bed a bit or drop the tank down using a floor jack and some 2x4's or plywood. (To keep it level and balanced.)

 

Thanks guys

 

Not to steal the thread but I'm planning on changing my tank what is easier move exhaust, receiver hitch, and drop tank. Or pull the bed off?

 

Few years ago I was filling my '77 and gas started running out behind the bed side.

Stopped, looked underneath, squirrels had eaten into the hose connection.

Got a replacement at NAPA, it was longer than needed, you cut it to length. I was able to get old off and new on with aid of vasaline and tightened clamps without raising bed or dropping the tank.

Then I bent up a piece of aluminum and slipped it in place to discourage further squirrel attacks.

So far, squirrels have eaten some tail light wiring insulation between the tails under the tail gate of the '77,
chewed on the new just recently replaced front flexible brake line from frame to axle on the '77 enough to warrant another replacement (I had recently redone the brake lines for the second time since I've owned it),
4" top side fuel vapor hose on my '07 over tank,
nicked the pressure line enough that it leaked,
almost ate through one wire in the harnes for the FPDM of the '07,
nicked a high pressure line on my '92 T-bird,
and I find walnuts in all kinds of places.

 

I found an intake snorkel and air cleaner box packed full of dry dog food on my '96 Powerstroke a few years ago.................wasnt squirrels.............MICE............little bast**** had been packing the dog food out of the shop and stashing it for winter I guess.......It was so packed in there that the truck would hardly run. Thats how I found it when I started investigating why the truck was running so crappy.

 

Are you guys sure that you don't have an ex-wife messing with you!!!! Ha! Never have heard of squirrels chewing on this stuff.

 

I think the squirrels are after the salt coating everything. I see them under my truck all the time. Hate them as much as meeses.

 

I don't think you can get the tank out from the top with the bed off. My exhaust is off to the side and the hitch plates are directly under the frame rails.

 

Yes, you can get the tank out with the bed off, but the bed is heavy as hell, so you need lots of helpers, if the tank isn't full, its probably easier to drop it

 

Yeah not sure which way ill go yet my receiver hitch must be a little diff cause its in the way and the exhaust also! That shouldn't be to bad to take off though! Inside of the tank looks prefect outside has rust! Thinking about using that rust killer and just use some rustoleum spray paint or are there better options?

 

I'd be killing some squirrels.
