Anyone know the sizes of these lines, need to Re-Locate the filler \ or extend them by about 2 - 4 inches, because for some reason, they cant reach to the filler neck hole in the bed.

 

Try one of these

 

Only thing that would make those connections too short is a body lift.

No body lift on mine, the rear half of the frame was rebuilt for the most part. So its either because the fuel tank was moved over just a touch or because it doesn't have the original bed.

 

Remove the old hoses, take to auto parts store and match. Gotta take them off anyway.

The main hose on my filler neck (91 4Runner v6) was 1-5/8" and no auto parts store in the area carried that size fuel hose. I ended up buying 2' of a marine grade fuel hose online and cut it to length.

Now, of course, yours could be a different size, but like Wabbit said, pull the hose and take it into a parts store, or if you need it to drive to the parts store, pull one end and measure it yourself.
