Another fuel filler neck replacement for a 510

Recommended Posts

I read through Creepy Cruiser's How to and used some of his idea's, see his here.


(1) So I also started with a filler neck from a 88-93 Mazda B2200.
(2) Couple of feet of 5/8 vent hose
(3) Newer gas cap
(4) and instead of a fuel filler hose from an isuzu i bought this. The reason I went with the new hose is i couldn't find and isuzu hose used or new. This is the hose Gates 23932 fuel fill hose 2" ID. This is the re-enforced hose with the steel in it. I also got the parts for the stock charcol filter to hook up to the 5/8 vent hose.

I used all the same tools including the tail pipe expander.

Parts I bought



So i was not sure how this re enforced hose was going to work when i was trying to get it to expand, but it worked out really well. So the mazda filler neck is just under 2 inches in diameter, the 2 inch hose goes over it very easily. I ended up cutting the hose so at about 14 inches, before you cut yours double check the length. To get the hose on the tank i boiled it in water with the expander in it. When i got the diameter right i dunked it in cold water. This seemed to help it stay at the size i needed it to. I also had the clamps on it while i was boiling it. Mostly so didn't have to fight to get them on after the hose was in place.







here are a couple of before pics

looks good but the only thing I see that I would have done different is put the  vent on top like the factory filler not down low where it can fill with fuel and not vent 

just my 2 cents but it looks great

Yes those leaks are fixed no more gas odor from there.....all my other connections are leaking though....  That will be fixed this weekend though.

What have people used for the Fuel Filler Neck or the Filler Hose for a wagon? 


I was starting to line up parts, then realized it probably won't work properly on my Wagon with that super sharp 90 deg down turn.


Should I just go get someone to fab up a bit of stainless tubing?


Note: I can weld - just not stainless.


Also, someone poke the 510realm owner to fire the domain back up. I feel neutered without it.
