Coreyfatboy Posted February 8, 2016 Share Posted February 8, 2016 My 16yo just picked up a 1976 Chinook with 5000 miles in a barn where he duck hunts. It has been sitting since 90 and had about 7 gallons of gas in it. Tank is shot. Does anyone know where I can get one or how I can make something else work. Thanks Quote Link to comment Share on other sites More sharing options...
payaso del mar Posted February 10, 2016 Share Posted February 10, 2016 that's the problem with duck hunting in a barn: it leaves lots of pellet holes in the roof where rain gets in and destroys things...... altho it does make it easier to retrieve your ducks afterward. OK, sorry, couldn't resist that. when you say shot, how shot? there are various products used for coating the inside of tanks, usually on motorcycles, to keep rust scale from trashing the fuel system...one brand is Kreem. if it's totally shot, i'd start with junkyards in desert states...NM, AZ, SoCal. I found no new tanks online when I looked. Plan B would be to drop n drain the existing tank, then take it with you to somewhere you can compare it with a newer truck tank.....I suspect they don't change that much from year to year (ie, the tank from an 83-88 generation truck might fit, and those are still available). you might need to do some plumbing and relocation of fittings but that's not hard with a new (never had gas in it) tank Quote Link to comment Share on other sites More sharing options...
Coreyfatboy Posted February 11, 2016 Author Share Posted February 11, 2016 Awww ya I guess I walked into that one?. So I had two pinholes in it and haven't even tried cleaning yet so I'm thinking the integrity of the tank is probably bad. I'm seeing the tanks that u are talking about they have 2 bigger holes on the top of them and mine only has one. One thing I'm noticing is that mine is an electric fuel pump in the tank. The 2 hole ones seem to b mechanical fuel pumps Quote Link to comment Share on other sites More sharing options...
payaso del mar Posted February 11, 2016 Share Posted February 11, 2016 Look at tanks for 85 and older ones with carburetor... In 85, they gradually switched over to fuel injection so the newer tanks have a hole for a fuel return line. Not too hard to close off the 2d hole if you need to. You can get 85 tanks for carb or EFI models. You may have to get the in-tank fuel pickup assembly to match the tank. I have to wonder if your in-tank pump is a retrofit....I've never heard of carb'd Toys using anything but mechanical. There are more expert folks here who will know that answer.

I've worked on, or owned - 1976, 1977, and 1978 Toyota trucks with carbs and all had in-tank electric fuel pumps. I don't know if Toyota ever made any truck with the 20R engine that did not have electric. Toyota trucks went through major frame changes in the early 80s and I suspect the tank mounts are different.

zero Posted February 18, 2016 Share Posted February 18, 2016 That link you posted doesn't bring me to any fuel pumps. I'm not going to say "never made" about any of this. What I AM saying is I've never seen any parts listing for a 20R truck with a mechanical fuel pump. When I look up parts for a 1980 - is shows me a "no longer available" electric pump in the tank if a 20R engine. If a 22R it shows a "still available" mechanical pump.

zero Posted March 4, 2016 Share Posted March 4, 2016 I wish I could get so lucky with finding a gas tank for my 2002 Chevy four-door 2.5 V6 4WD Tracker. Seems to be a REAL odd-ball. I found a few in junkyards but nobody will ship. Pickup only - and the closest so far is 300 miles away. The ones local to me come "pre-rusted." New ones seem to be discontinued. Sad thing is - my Tracker is from Kentucky and has no rust. Seam is leaking. I was hoping to just swap in a good tank instead of pulling this one and jerking around with it.

I have not done a parts search since last Fall. At that time - I called every place listed in car-part.com. I have not looked lately. Tracker is off the road for the winter (sort of) so it hasn't been on the top of my list. I try not to drive it on road salt unless I really have to. Use it more in the spring and summer.

Coreyfatboy Posted March 8, 2016 Author Share Posted March 8, 2016 The only thing I need to figure out is if there is a pressure regulator some where. I am going to have to put an electric fuel pump in line on this tank Quote Link to comment Share on other sites More sharing options...

I am going to have to put an electric fuel pump in line on this tank All you need is a low-pressure fuel pump. No extra regulator. Something that runs at no more then 4 PSI. If it was my truck I would buy a good fuel pump made for sucking fuel from a tank not made for electric and also with a very long service life. Those little rotaries and pulse pumps like auto parts stores do not fit that category. I'd use something like a Walbro FRA-2. Runs at 2.5-4.5 PSI and has a projected 5000 hour service life. That's like 250,000 miles in car-talk. Quote Link to comment Share on other sites More sharing options...
Coreyfatboy Posted March 9, 2016 Author Share Posted March 9, 2016 Ok on to the next problem. My old tank had one hole in top with a 2 prong electrical plug I'm assuming one to run sender and one to run pump. The new tank I got has 2 holes one is sender and one is pick up. So I thought there would b one wire going to the sender and I would use other to power in line fuel pump. When I went to hook things up I found that there is 2 prongs on the sender in the same configuration as my old tank. I believe the wires to be ylw/rd and blk/rd. Any ideas what wires would go where Quote Link to comment Share on other sites More sharing options...

One wire is dark - perhaps black with a red tracer (stripe) and that is the POS for the fuel pump. The other wire looks like white (or something light) with a yellow tracer (stripe). That goes to the non-grounded side of the fuel-gauge sending unit. There was NO ground wire on the Chinook and is kind of a poor setup. Later Toyota trucks use a separate ground wire instead of just bonding to the frame. Quote Link to comment Share on other sites More sharing options...
Coreyfatboy Posted March 9, 2016 Author Share Posted March 9, 2016 So the dark wire will be power source for fuel pump and the yellow for sending unit. Do I need to run a ground wire off off the other prong on sender Quote Link to comment Share on other sites More sharing options...

I'd have to see it to say for sure. I have a 1987 sending unit from a Toyota truck sitting here. It has two terminals and one is for a ground wire. Easy enough to tell. Just stick an ohm-meter on the wire that you think is a ground and check for continuity between it and the metal part of the sender. Quote Link to comment Share on other sites More sharing options...
Coreyfatboy Posted March 9, 2016 Author Share Posted March 9, 2016 I don't believe either of the wires are ground. I was wondering if I need to ground the sending unit since it has 2 prongs and I only have 1 wire, yellow , that I think is powered Quote Link to comment Share on other sites More sharing options...
zero Posted March 10, 2016 Share Posted March 10, 2016 You've got me a little confused. Which sending unit are we talking about? The 1976 Chinook sender only has one wire going it. To complete the circuit is uses the metal of the holder that makes contact with chassis ground. If you are talking about a sender from a newer truck - I'm not sure what you have. Some time early to mid 80s, Toyota started using ground wires to the sender. I don't know what you have. Post a photo. If you want to check for sure - just stick an ohm-meter between the two terminals and move the float on the sender up and down. Should go from around 2 ohms (full) to 100 ohms (empty).

Coreyfatboy Posted March 10, 2016 Author Share Posted March 10, 2016 Ya I'm using the wiring from a 76 and the tank from an 81. Sender on 81 tank has 2 prongs on it so I'm wondering if one of the prongs I need to just ground Quote Link to comment Share on other sites More sharing options...

It is just a variable wire-wound resistor with a lead at each end. No polarity to it as long as you are SURE it has no continuity to the metal it is mounted on. Either end can go to the chassis -ground and the other to the sender. Quote Link to comment Share on other sites More sharing options...
