Anybody out there have a secondary auxiliary tank for there toyota made by a company called "auxiliary fuel systems" "AFS" out of Hemet, CA

Reason Im asking is I have one, but I broke one of the fittings in the woods and about left myself stranded when I dumped nearly all the fuel out of both my tanks. AFS has been out of business for 15 or more years now. hoping somebody knows about the fittings.

Here is a pic of the tank.



this is what is left of the 90 that worked as a gravity feed line to the main tank



Its made of some sort of rubber material and has a 'O' ring in between the tank and the fitting.



If anybody has seen these types of fittings or knows what they are or how to get them, it would really help me out.

If there is also a better place to post this type of question, let me know and I'll try over there. thanks again.

I merged your posts into one to make it easier to read...

I remember seeing ads for that company in Peterson's mag back in the day... did'nt know they were out of business... No idea where you could get replacement fittings...
can't tell from the pics but if it is a metal tank it may be possible to install a replacement fitting. this may entail cutting open the tank from the top to get access to the bottom corner where the fitting is to install it. This may require cutting open and welding the tank closed again... there are specialist shops that can do this kind of work safely... check under tank repair in the yellow pages... if you have no listings there try under steamfitters or boiler repair...
Hope this helps...

Just had a thought norcal... have you tried a boat repair yard? the tank fitting looks similar to some built in boat fuel tank fittings... they may have something you could use or be able to adapt something for you.

Oh! and I changed the title of your thread to make it a little more clear what you were looking for.

Thanks for fixing that, it was kinda jumbled.

The main issue Im having is the tank is some sort of thick plastic. Otherwise I think I could fix it like your saying if it was metal.

I tried a few local tank welding shops and they all said they've never seen fittings like that, but they all fab metal tanks.

Was hoping someone else had seen this type of tank and new how to get the fittings. OR maybe how to fix the existing.

That might be a good idea. There are a number of boat shops around here by the lake. Maybe they will have something or might be able to fill the hole with some type of plastic resin so I can tap threads for a better fitting instead of funky rubber one. Thanks

Also, if anybody knows how to weld plastic in the northern california area, Id be interested in talking with you to try and fix this. I have a parts 93 4runner that I got a few days ago for the motor. Id be willing to trade parts for the plastic welding work as well if that would interest.

I suggest boat repair or maybe RV repair shop.

Keep us posted if/when you find a fix for it, I'm sure this kind of thing is going to come up again one way or the other.

Not many companies selling ABS/PVC/related fuel rated tanks.

Inca Plastics is one, but the Ontario, California facility doesn't like working on fuel tank. I know: I used to work with them when I worked with Weekend Warrior/ a.k.a. Warrior Manufacturing (spin off of Alfa Leisure) and Carson Trailer on their toybox a.k.a sport/utility trailers. We sub'd fuel tanks to a shop in Ontario, Cali, who built them from stainless.

Inca Products is another company (related to Inca Plastics, but specialize in marine fuel tanks). I haven't dealt with them so don't ask.

Comes down to who does roto-molds tanks and who can service them.
So, marine and RV are the likely "target" shops to do repairs.

how is that fitting attached ,is it screwed on ? cant you just put a brass fitting on there.

Thanks for the ideas fellas. I'll make sure to keep up with what happens. Ive been trying to figure out if its worth fixing or if I just need to junk it and get a metal one. This tank is kinda a pain in the arse anyway.

I'll try the local RV place and then take it to a few of the boat shops and see what they say. May take a while but I'll figure something out. Just a little distracted with putting a motor in my wifes 4runner, but this project is on the list.

I wish it screwed on. Then it wouldnt have been such a big deal and I could have screwed a new fitting on. It turns but isnt threaded, just that rubber washer and the rest of the rubberized fitting goes inside the tank. Almost like the plastic was heated and then the fitting was pressed in and allowed to cool around it or something. Just odd. I could just start to pry and tear things out, but I want to exhaust all other options before I do something that cant be undone. Figured it was worth a shot to see if anybody else had one or knew.

Like a PCV valve?

have you googled plastic welders?
there is a place I pass every day on my way to work that advertises plastic welding..

Turd Furgeson

It was just a 90* nipple? Break the rest of it out of there,find a brass,or steel 90* nipple of the correct size,take it to a radiator repair shop and have them weld a steel bung in your tank (or solder a brass one in) and screw your new fitting in. Or just have them solder/weld the fitting directly in there (depending on material). They will have to boil the tank out (or flush the hell out of it) first to get the fumes out. If your tank has any rust starting in it,now would be a good time to have them put a liner in it while it's there.

It's a plastic tank so those options are out Turd.

I wonder just what type of plastic it is would the PVC glue work and hold be no big deal to glue a threaded fitting in or even expoy.

What I can`t see is you have no stand off or at least you know of so all the dirt just gets drained into the main tank.

Just how big is the tank? I am thinking just replace with a fuel cell and be done.

If you had the first fitting break how long till the repaired one breaks

Im not sure what kind of fitting it is. Doesnt make me think of a pvc.

Glue or epoxy might work and it may be an option. The fitting is a some sort of rubberized material and not plastic. so it has a lot of flex to it, maybe because of all the movement in wheeling. The rest of the tank is a thick plastic and thick enough to be welded as shown inthe pic. I may have to get a plastic welder and give it a shot. Ive seen little kits at harbor junk, but Ive not always had the best luck there, but something Id prolly only use once.

Tank and fitting lasted 15 plus years. It prolly would still be working had I not got hung up and tore that gravity feed line out. There was a fuel fliter I put between then two tanks on the gravity line. That should have been the break point but it cracked the pictured fitting so I had to cut it the rest the way off so I could zip tie the remaing line higher then the stock tank so I didnt lose the rest of the fuel. Otherwise I still may still be out there walking looking for someone to bring me home

I think if I do it right and plastic weld something in there, or thread something for a new fitting. Might get another 15 out of it?

eric924run

pry the old fitting out then tap the hole. get a pipe thread tap. screw in a brass fitting from home depot. put some pipe dope on the threades or gas thread tap.

aviator

The tank will be thin plastic... no tapping that reliably...
