I couldn't find a fuel pressure tester locally that had the proper fittings for the 22re coldstart injector.

I could put a tester in line w/ my fuel pressure regulator using a hose, but that wouldn't tell me if my FPR was working properly.

I ended making one for about $20 from princess auto (harbor freight). This is probably obvious for lots of people, but I was very annoyed when none of the tool shops around here had the proper fittings for a commercial product.

Parts:
-----
-piece of 1/4 ID hose
-2 hose clamps
-Glycerin filled 60psi guage

-female 1/4nptf to 1/8" nptm male adapter
http://www.princessauto.com/power-tr...-m-x-f-reducer

- m8 banjo bolt and nut (Thread pitch doesn't matter), shank should be about 1" or 25mm long. I just used a bolt I had around and drilled it out to be a banjo union bolt.


Construction
------------
The hydraulic adapter is just to adapt the hose to the pressure gauge w/ the hose clamps. Apply some thread sealant. Screw the adapter onto the gauge, slide the hose over the adapter, hose clamp tight.

The banjo bolt was surprisingly easy to make... Probably much easier then tracking one down. It has to be roughly 1 nuts height longer then the stock bolt. If you could find a very thin m8x1.0 nut (~<5 mm), you could probably use the stock CSI banjo bolt.

Connect
--------
Put a washer on the bolt, slide through CSI, add the other washer. Wrench the nut down onto the bolt so it's all a tight fit. Attach the hose to the remainder of the bolt threads and tighten down w/ the other hose clamp.

I didn't take pics of it in operation, but it worked well with no leaks.

Hope this helps. Besides the drilling of the bolt, the whole process just took a few minutes.

 

very cool

I hope you're using hose that's able to hold that kind of pressure

 

Nice job

 

Nice work.

But I wouldn't walk away from a hose-slipped-over-the-end-of a bolt under fuel pressure, not even for a second. (So I wouldn't try to start the truck, unless someone was staring right at the fitting.)

Now that you have the rest of the parts, you might think of getting the real banjo bolt. The 8mm (at the cold start injector) can be had from Actron http://www.actron.com/product_detail.php?pid=16288 (this connects to an Actron Fuel pressure guage, which I believe has a non-tapered thread). Perhaps a better connection would be at the Fuel Pressure regulator, with a 12mm banjo bolt drilled for a 1/8" tapered thread (which you already have). http://www.autozone.com/autozone/acc...ntifier=373289 or http://www.jegs.com/i/Auto-Meter/105...oductId=749158

 

The Actron fuel tester was not available in any of the stores I went to. I would have purchased that product and it's banjo adapter, but I did not want to order from the US. Things are slow to get across the border sometimes and occasionally you get charged duty. I wanted to know the answer that day.

That tester is available as a rebranded product under the name equus.

Unfortunately, I went to 5 stores (canadian tire, lordco, napa, kms tools, princess auto) and none of them had the banjo adapter, even though they carried the tester.

Included with that actron/equus tester are hoses and hose clamps, which is where I got the idea in the first place. If they are able to sell that as a commercial product, it should be more than safe and suitable.

I also used a 3 foot hose, so in case my end fittings leaked, it wouldn't leak all over my engine. It didn't leak.

Scope103, I'm confused about your comments. The FPR on a 22re does not have a banjo fitting. How would that bolt help me test my fuel pressure?

What I could have done is kept the equus fuel pressure tester kit and make that banjo bolt adapter myself. Or waited a few weeks for it to arrive via mail.

If I am going to have to make my own adapter anyways, might as well take the $20 solution instead of the $60.

I thought about getting a shop to test my pressure for me, but I figured they would charge me at least 1/3 of the price of a new tool (love new tools). In the end, for $20, this setup worked perfect, did not leak a drop of gas and solved that nagging q that has been in the back of my mind for at least a year.

 

Sorry, I went and looked at my truck. It is a banjo bolt for the FPR.

That larger banjo bolt should work, but then you wouldn't be able to test your FPR.

 

sick, im gonna head to princessauto and get the parts

 

I'm not sure I understand that. The entire fuel rail (and the line to the CSI) is at the same pressure, set by the Regulator. Where ever you measure it you should get the same number. Perhaps you thought I was suggesting you remove the regulator itself and use that as an access point. Instead, I would suggest removing the banjo bolt at either end of the line to the CSI, and replace that bolt with an 8mm banjo bolt with the NPT thread. (I have a 3VZE, which is not as convenient for access to the rail. On the 3VZE, the easiest access point is the 12mm banjo bolt near the regulator.)



You did a good job, and thanks for sharing the details.

 

I am planning on testing the pressure on my 22rte...which would be similar to the 22re....The question is, what size banjo is the CSI? I am looking at this kit bit it comes with a 12x1.25. Is there a 12x1.25 banjo fuel connection on the 22re somewhere?

Thanks

 

The CSI banjo is a m8x1.0.

This is the adapter you need to check your pressure w/ that kit.

That kit is the same as the one I linked to in the 5th post (just rebranded) and won't work without the adapter.

 

Does anyone know where I could possibly find banjo bolts and adapters at a local retailer so I dont have to order them online? Or where I could find the fittings to make one?

You might be able to save a few bucks trying to build all these parts yourself. If you're a really good machinist you might be able to build one with $25 in parts and 3-4 hours of time. Think carefully about taking any shortcuts; if you have a fuel leak in the engine bay, the expected service life of your rig could be measured in seconds.

 

Is is possible to install the banjo bolts so that they restrict the flow of fuel?
i know a twisted fuel line can give the bogging at WOT i am having,but when i put the fuel filter back on, can I have turned the banjo bolt say 90degrees off, and restricting proper flow of fuel?

(we are talking rebuildt 22re, runs and idles great, only bogging at WOT when you hit the linkage fast. Also present when TPS out)

 

I doubt it. The "banjo" has a toroidal (donut-shaped) space all the way around the bolt, so the alignment with the hole through the bolt shouldn't make any difference. Besides, like all ordinary bolts the banjo bolt is a single-start thread. Which means that you can only start it one way, and when it's tight there's only one way it can be pointing. So if it worked from the factory, you can't reassemble it "wrong."

 

what is the spec on the fuel pressure?

thanks for the link! still havent been able to come up with a pressure gauge to test pressure but like lc eng pressure gauge kit they offer. for now i will try and build my own.

 

hope this works... i found a gauge to use, and i found some banjo fuel lines off a 91 celica engine lying around with banjo bolts. i have a larger line and a smaller line off the celica w banjo bolts. just tryin to peice it together

 

tryin to post a pic of the gauge. sorry if it doesnt come up. been awhile since i uploaded pic.[IMG][/IMG]

 

Just make sure you can do it for less than $50, and at the same time avoid setting yourself on fire. It's pressurized gasoline, after all.
