I pulled the guts on the fuel solenoid while struggling with air in the fuel line…do I still need to leave the key on?

Thanks.. I almost pulled the glow plugs so turning the motor over would be easier when screwing in the timing gear but just went for 24mm on the balancer..the question that came to my mind since I don’t have the glow plugs attached to the wire am I at risk of any damage didn’t hook them up...

Thanks I’ll try that tomorrow…glad to know that It’s not electronic

Okay replace the seal on the injection pump and put it back on the truck yesterday…no more river in the valley and no more air in the clear return line…BIG shout out for the help on identifying the leak and also the injection pump rebuild kit…My eyes are tired of reading..can anyone tell me why...

Thank you Will L. Well explained…just looking at the picture I’m guessing DB is mechanical and DS is electronic…I get it now

I know that is confusing me…I thought seen ds4 and also thought there was db4 but not sure…is there a db4 and ds4 ?

Well got my injection pump rebuild seal gasket kit…whoa intimidating soo many parts..thanks MrMarty51 for the link has the keyhole gasket (seal) in the kit…pulled the injection pump this afternoon…and also thanks to Paveltolz for pointing me in the right direction, I was at a loss thinking how...

Perfect…thanks so much

Alright holding off on ordering the DB4 injection pump rebuild kit 33702 because I fail to see the seal I think I need..no way I’m going to rebuild the pump but looking to replace what I think is leaking…posting a pic of the seal that might be leaking and the rebuild kit…am I missing something??

Thanks for looking. I did see some for around $55-$60 bucks and they want $20 for shipping and the weight of the package 1lb….they call them aftermarket which probably most are…which I would go with but while looking at the pictures I don’t see any that resembles that gasket (seal)I thought it...

Very much appreciated…thank you for the time. Sincerely panran

Towed the truck to Colorado finally and now can work on it again. Stanadyne DB4 injection pump never could stop the bubbles in return line but finally tracked down the source after removing the lower intake a dozen times. Replaced lines to and from ffm and also replaced ffm housing because the...

When I gutted my fuel shutoff solenoid I mangled it a bit or bent it and it didn’t seem to sit right…that’s why I lost sleep and glad I took it back out..wasn’t seated all the way…I’ll try and find one tomorrow and post the size if I don’t find one I’ll try to bend it back into shape

The part is reassembled and works .. but when disassembling the retaining ring got slightly bent and I just worried about it…thought someone might know the size metric or inches and diameter?

Woke up in the middle of the night and tried searching for almost 2 hours and decided to ask: size of the internal retaining ring on fuel shutoff solenoid? I gutted mine and while removing it I must have bent it because upon reinstalling it…it doesn’t sit exactly right and rather than chance it...

Yes I noticed when I have the lift pump running.. I have a leak towards the back of the engine I’ll get under the truck in the morning…so I didn’t realize that would cause the air in the fuel line good to know and I’ll put cut off solenoid back together…thanks

I’m just now getting it.. I was treating the lift pump like I did the starter 15-25 seconds at a time..lol

Alright, so I gutted the shut off solenoid so I don’t have to crank the engine..turn the key on and jump the lift pump and leave it…okay I was worried about burning out the lift pump…by the way where does all that air come from?

Thanks for not giving up on all my questions gentlemen .. I almost gave up while jumping the LP and looking down in the IP seemed like no fuel was rising, kept saying last try and when I meant last try I looked over and the fuel was at the top..so I put the outlet valve back in and cranked it...

Sometimes I overthink but this question just popped in my mind…should I take the fuel lines off the injectors ( they are already loose) or will the bad fuel be directed out the outlet?
