So I bought my 1980 pickup a couple of years ago, being my first toyota I didn't know too much about them admittedly. I assumed there was a 22r in it, because of the big sticker on the valve cover!



One day I realized it had a 20r style carb on it so I figured it was a 20 with a 22r valve cover. Being that it ran like a top I wasn't too upset.



Well recently my ignitor took a dump and I let it sit for a few months before I got around to changing it out for one off of a parts truck I acquired. Got her firing again and low and behold now my fuel pump seems to be done for. Well...that's where I realized something fishy was going on, being that most 20r's have electric pumps and mine obviously has a mechanical one. So I needed to find out once and for all what I actually have. Turns out it's neither!



Lucky me it's the fabled 21r!!! Everything I read says parts are super hard to find if not impossible.

So long story short and being I need a fuel pump, do any of y'all have any idea if a 22r pump will work for simplicity of location and what not, or will my best bet be to go with a electric pump down by the tank?


Thanks fellas

Wonder if it was a import motor swapped in.

Seems a 20 r or 22r swap might be in you horizon.

Yes 21r is an import motor, here is what wiki has to say about it:

The 2-valve SOHC 2.0 L (1,972 cc) 21R was produced from 1978 through 1987.
Cylinder bore was 84 mm (3.31 in) and stroke was 89 mm (3.5 in).

Output in 1978, constrained by emissions, was 105 hp (78 kW) at 5,200 rpm and 116 lb·ft (157 N·m) at 3,600 rpm. Air injection and emissions equipment for the 21R-C (1982–1985) dropped power down to 90 hp (67 kW) at 5,000 rpm. The air-injected Japanese version, the 21R-U, produced 105 hp (78 kW) at 5,200 rpm and 120 lb·ft (162 N·m) at 3,600 rpm but dropped to 101 hp (75 kW) at 5,400 rpm and 114 lb·ft (154 N·m) at 4,000 rpm in 1986.

Applications:

1978-1982 Toyota Carina RA46-A, RA56-A
1978-1981 Toyota Celica RA46-B
1981-1983 Toyota Celica RA60-B
1978-1983 Toyota Corona RT133
1978-1981 Toyota Cressida/Chaser RX40, RX41, RX60
1979-198? Toyota HiAce Wagon RH23G

I'm pretty sure the 22r pump will fit but can't say 100%

"Nice" find - could be fun, could be a nightmare! The fuel pump looks to be the same as a 22R, but can't be certain. Remove it and take some detailed pictures and I'm sure we could help you out. The 22R fuel pump is actually stocked at most parts stores so you could always go to the store with your old one and compare.

BTW, I updated the thread title to be a little more descriptive. With what you have under the hood, you'll likely need all the help you can get.

Cool! I have heard of the 21R but have never seen one.

Thanks guys, I'm going to give a 22r fuel pump a try, when I get some time to work on it. I will definitely keep everybody updated on what does and doesn't work with these motors.

As long as this one keeps running well I'll leave it and probably begin the process of rebuilding another motor. I have a rebuildable 20r but if I'm going to go through all that work I think I will try to find a 22r to go in it.

Sorry for the late update, turns out 22r fuel pumps work on the oddball 21r! Got it put in and driving last weekend...thanks guys!

years ago (early 90's) my first 1gen threw a rod. rather than rebuild I opted to by a dock motor from a place in LA. for all intents and purposes it appeared identical to my 22r but turned out to be a 21RU not sure what the "U" stood for. I can tell you though that most of the parts from the 22 bolted right on. (all as far as I can remember) timing chain/cover and all(double roller). never had any issues with gettin parts from the local parts store, just ordered for the 22R. of course it ran for 200k plus miles without much need for anything. disclaimer*** it was twenty somethin years ago and my experience is purely anecdotal. take it for what you will.
