Problem 1993 Holiday Rambler 34 Gas Tank Fill Issue

[Megaro76]

Hello
My new to me HR AlumaLite 34 class A 460 gasser on Ford F53 chassis has the issue I have heard of where the gas pump clicks off even at the slowest fill rate

After looking underneath and following the fill tube from fuel door on the driver side to the tank, it appears the fill tube is original with a noticeable dip before entering the gas tank. Does anyone know if this is correct? I’m going to take some pics to help show what I’m working with. Hoping to get resolved for upcoming trip
Thank you all in advance

It's common,not normal. Get rid of the "P" trap and the fuel will flow.

See pics. Most of the fill tube is steel with I’m guessing some type of undercoating/sound insulation sprayed over it with the exception off the 8-10” shown with the hose clamps. @Kevin D Pem Thank you for your reply about getting rid of the p trap. I have tried pushing up and that section and it is pretty well fixed in place to the point I started to rip the screws holding the fill tube entry part behind the fuel door. So strange. I’m hoping some can offer tips to try in getting fuel flowing. I have not had much look at local rv services saying it just is what it is unless I want them to pull tank and make something custom.
