QV fuel line replacement question

Guys, I've changed all the fuel lines on my 84 QV with exception to the hose that attaches to the fuel filler neck and gas tank. here's why, I purchased the two crossover pipe hose and the filler neck hose from GT car parts in AZ. and the rest of the hoses from desire 308 (peter) The crossover pipe was a breeze to change but I fought with the filler neck hose for 2 hours, finally I pulled a tape on the old hose and it says 55mm inside dia. the new hose is 52mm id. so I call up GT parts and tell them the hose is the wrong id. and dave tells me they buy 10,000 at a time (hard for me to believe as their are not that many cars left) and I'm the only one who has complained, then he tells me to heat it up and that will help. I have been lubing the hoses with dish soap as it makes rubber slide easy and then dries unlike vaseline. So, does he need to take a drug test?( I would think this would compound problems) or does it work, 3mm is alot of expansion. thanks for your input.

 

Thanks for the help guys, but the napa hose measures 2 1/4 inches inside dia. and the one I cut off measures 2 1/8 '' id. I'm uncomfortable with the difference. Hate to see my car go up in smoke.

 

Thanks guys! Paul, thanks also! Guess I was just looking for that "you'll be fine" post. Dan, I appreciate the offer! I'll try the boiling water idea first and see how far I get, if I can't make it fit I'm off to napa.

 

Michael thanks, just got the napa hose, the boiling water thing didn't work well at all. The thing I don't like about vaseline is that the hose stays slick, a little soap will dry and disapate. I have another question, There are 3 steel braded fuel lines on my QV. two that connect to the fuel distrubition piece and one down in behind the fuel pump. I would think I need to change these also as they are true fuel lines not vapor lines, is this the norm? not having much luck finding replacements.

 

Verell and Michael Thanks for the info. I thought they were rubber. I'll probably just leave them "as is" for now. I tried to get them from Fer parts but they said they would have to call Italy and the factory is closed for the whole moth of aug. Thanks Again! Kim
