Builds 1985 BJ70 Story and Modifications (1 Viewer)

[AlbertoSD]

I then replaced the primer pump, re-bleed the system and the truck started again as it did when I fired it up. I shut it down and re-started it after a couple of minutes and it was fine.

However, I went to start it the next day and it had the same symptoms as it did before. It seems that it is loosing the prime or letting air in somewhere. The first few times (before it starts again) the smoke is white (indicating lack of fuel) and then it starts and iddles fine. But then the next day it will not start easily.

I will start inspecting all the fuel hoses and such...but am I missing something obvious?

Any thoughts??...any help and guidance would be greatly appreciated.

Thanks!

Bump for some help

Also, anybody know where to source the bronce washers that go on all the banjo connectors of the fuel system?

Thanking you in advance for your help,

Hi Alberto,
These washers (usually copper) are all still available from toyota, but you need the part numbers. Otherwise places like harbor freight carry assortment of copper seals/washers and you can find them on ebay.

Thanks, Jan!

I think that these washers are the cause of my air-leak. I had to swap the bleeder fitting on the fuel filter assembly as it was in the wrong place (it was on inlet of fuel filter rather than outlet) and I think that I should had replaced the copper washers.

Once the truck starts it runs great, but doesn't like to start if you leave it overnight.

Just ordered the washers through Toyota. The Part number is the same as listed in Toyodiy:

Part # 94712-77121

What other places are suspect for air-leaks?

Thanks again,

Had same issues on a dodge diesel, start at the tank and replace all the rubber hose with silicone, I use Parker hose rated for diesel and hydraulic apps. The solvent they are selling as diesel fuel is hard on everything it touches. If that and the copper washers don't solve it you can rig up a pressure rig for your gas cap and put 5-10psi in it no more and look for the fuel leak..

I ended up borrowing one from a diesel tech on one truck, the suction lines don't see pressure so they don't leak fuel but do let air in. By pressurizing the tank and lines any leaks show up instantly..

Good luck the first one about drove me nuts as it was a braided steel line that was leaking and didn't know until we pressurized it. I didn't mess with them as everyone said those never leak..well they were wrong...

Good luck and great thread...

Will spend sometime looking at all these little things...amazing how time consuming it can be.

Thanks for the note,

Alberto-
Beno was able to get some for me last year when he was at American Toyota (now Larry H. Miller Toyota). He's with Proffitt's now. Cruiser Dan can probably order some for you as well (/vendor-marketplace/17873-getting-cruiserdan.html).
I was able to get the washers so I could check/clean the little metal mesh filter that is supposed to be checked/cleaned every few years. Let me know if you need part numbers- I should still have that laying around.

Thanks, Rob!

Got them ordered at the local Toyota dealer...we will see how soon they get in.

Thanks!!

The mesh filter is the "Fuel Feed Pump Filter", part no: 22529-67010
The washers (they are called gaskets in the maintenance manual) are the same ones that you have already put on order. The information on the cleaning schedule is in the Toyota Maintenance Procedures manual. Mine is for 1986 models, publication MM001U. It is a 5MB file if anyone wants it. I'm not sure if it came from TrollHole's stash or elsewhere, but I'll send it to anyone who asks. izula001 gmail.

Thanks again, Rob. Just sent you a PM with my email address to get a copy of the Maintenance Manual.

Did some work on the BJ70 this weekend. Got the washers from Toyota and started replacing them everywhere I knew there was one of those. There are two washers per banjo connection (one on each side of the banjo bolt).

 

[AlbertoSD]

I will make sure that all fuel hose clamps are tight and try to see how it starts. If this fails, I will do what Ray (RAYJON) recommended and pressurize the system to find any leaks. Really want to get the truck ready soon.

Thanks for all the advice, guys.

[crushers]

another important consideration is where the washers sit, BOTH sides need to be completely clean of debris or rust ...
best of luck

Thanks, Wayne!

I hope to get it running well this week

 

[RAYJON]

make sure to only use 5-10 psi, you only need enough to check for leaks, too much can cause tank to balloon.. good luck,

my 13BT was having a similar, intermittent, starting issue. After a day or two of sitting, the truck did not want to start (and this is a 13BT, direct injection... it fires right up without the glow screen). Sometimes it would start, then immediately die. I cracked the bleeder screw, and was getting no fuel. I ended up disassembling the stock lift pump... expecting it to be a mess. But all the pieces inside are metal. It all seemed clean and fine, and it went back together... and fired right up.

It was fine for a week. Then it happened again.

I finally got fed up and added a Walbro. I am not normally one to put a band-aid on a problem without finding the real problem... but I guess that is exactly what I did. Anyway, the Walbro went in and I never thought about it again.

Thanks Ray and Brian,

These will be my next steps. Got a few of the items and now I'm searching for the right fittings to make it work.

Thanks for the guidance, guys!
