attempting o-ring fix on IP
Picked up all parts and tools to do this job. Does the fuel deleivery valve come apart as you are pulling it out? If so, is there any proceedure to take it out and or put it back together? I'm doing this without taking off the intake manifold as described in an earlier post. Thanks to the person who posted it. Does anyone have part numbers and vendor for replacing o-rings in Viton to prolong lifespan. This forum has been great in providing information.

I've not removed mine so can't say for certain, but i beleive it has a 1/2" nipple inserted into the IP and pulls straight out.
The o-ring part sizes were posted recently as was a photo of the shutoff valve. If you dont find them PM me and I will send tham to you this evening when am at home.

Thank you, I bought the OEM o-rings from the dealer and if it's easy enough I'll pull them back out again and replace with the Viton ones. I'm betting I won't want to do this job very often.

you need 12 total- 6 rubber and 6 copper crush washers. be carefuland read the directions on this, if they aren't torqued correctly, they will leak!

I would also advise removing the intake manifold. 20 minutes of removal time will make the job SOOOOOOOOO much easier.

Wow...my post was way off base...read too fast and thought the question was concerning the shut off valve o-ring. Missed "delivery" valve completly.

IP disaster
I started the job last night and I didn't go as planned. The delivery valves were a real mother to get out. I dropped one of the springs and was unable to find it. Need to go to the dealer and see if they can get me one. I need to at least fix that one to move it. It is impossible to torque them with the intake on. My wife suggests I take it somewhere and get it fixed. After all the fuss, I totaly agree. I have no doubt that this problem was caused by the changeoever to ULSD in that I first developed leaks in the clear lines and onced fixed had new leaks in the IP pump delivery valves. I all happened so ubrubtly.

I don't know about the change over to ULSD causing the problem.

Delivery Valve Spring
Folks,
After I retired, I worked as a Bosch Fuel Injection Tech Rep for a little while. Go to your local Fuel Injection Test/Calibrate shop....they should have some in stock, or perhaps a used one in a tin can someplace..... SB

Delivery Valves
Quote:
You sound like the right guy to ask: When I did mine, my magnet also pulled up a lower sleeve along with the spring, piston, and sleeve at the top. The bottom one has a slot milled into it, and two different sized holes oriented at 90 deg to the slot. I pulled another one also to see how they went back in, and it looked like the slot should be to the rear, and they went back together smoothly like that. However, these two valves are still not delivering. Is there some kind of pin that dropped out when the bottom sleeve got pulled? Do I need to replace the pump? Thanks, Gerry Visel gcvisel@gmail.com |
