My only issue with your Dmax filter setup is the primer seals probably won't take more than 10 psi without starting to leak. I would delete the primer button, you don't need it. That's why I bought the Dmax van setup, no primer bulb.Well I know how everyone loves diesel porn so here are some photo's of one of the fuel system's I've been working on.There is no DATA to show that there is any advantage to using this system. This system also requires dropping the fuel tank and adding a 1/2 inch pickup tube so I'm not sure if and when I will actually be putting this setup in service.
If it ran fine before swapping the pump and injectors, then you know the answer,So just to clarify what I did next, I cracked each individual injector one at a time while idling and there was no change when I cracked open #1 and #8 then I installed a original injector in the # 1 cyl and it still didn't fire #1 then I put the #2 injector that I know fired into the # 1 cyl and put the #1 injector that wasn't firing into the #2 cyl and the miss stayed in the # 1 cyl. I also did the paper test on all of the intake ports and they all only pulled the paper into the port no pressure coming out of the intake ports. I also ran compression on #1 and # 2 cyl and they where the same but the tester I have doesn't read accurate but I would trust it to be equal or consistant from cyl to cyl. I don't believe there is any engine damage, it ran fine when I removed the pump and now it doesn't fire on #1 and # 8 cylinders, I believe the issue is in the pump but I could be wrong but I'll bet $100.00 that if I run compression with the correct gage that every cyl would be within spec.
Its a kit, used this setup in my 84 G van, works awesome. I took it out of the cage and made mounting brackets. Didn't use the cooler, don't forget the return line and wired it to turn on with the engine on. Ford uses the same pump, so its replaceable. I didn't know this and killed it with a bad batch of WMO.Dmax van setup part numbers?
Gm built special ones for marine diesel nuthe OP indeed sent us the spec sheet on his IP, we could not find out much about it, the part number he posted is a dead-end, it appears to be a peninsular number, but we did not find out much with it.... appears to be a number that states .350" plungers, but this only exists in 4-6 cyl. configuration, so this leads us to believe that its either a one off custom H&R, or someone did some modifications in it. cannot be sure of the internals without measuring. we also have a flowbench sheet that he sent us, maybe he will post it up for everyone to see, or maybe one of our pump gurus will come in and explain the configuration.....
Db4 pump is better than db2 for fuel specailist setup thats why hammerheads 300hp used them with blower 5.7 ltrWhom is it that told you that much more fuel is available ? Many will say it is easy. For us, there is only two shops that we would trust with a DB4 pump.
The DB4, is a much different pump than a DB2. Definitely needs to have a tech whom is familiar with it to do any adjustments, as the plungers need to be exactly balanced, or they will work against each others. This is probably the reason they blew your pump up, and the primary reason that the cam pins break, even though it is a substantially larger pin than that in a DB2 pump....
Why do you want marine injectors? They flow less at lower rpms.Does anyone have the part number for the genuine BOSCH 311 injector nozzles? I believe ProCycle had a thread about the so called "MARINE" injectors probably quite some time ago I believe with this info maybe.
Marine deisel used db2 pumps for 170hp and 250hp then db4 for 300hp and 410hp enginesWell I went and bought a new compression tester and tested cylinders 1,2 6 and 8 and they are all @425 while I was at it I swapped injectors from #1 inj to #6 cyl and #2 cyl to #8 cyl and then #8 to #2cyl and #6 inj to # 1 cyl I hope you can understand that and I started it, I went to grab my phone to shoot a video of what I was doing and the engine shut off. It appears that the shut off solenoid has failed, it has 12.97 volts to it put it does not make a sound and now I can't get any fuel out of any injector line. My intentions were to remove all of the injectors and put small clear bottles on all of the lines and crank it over to compare the fuel discharge from the pump to each line but with the shut off solenoid failure I can't do that now. I tried to call Mel @ Conestoga today but I could not get anyone on the phone maybe due to the holiday, I will try again tomorrow
My injector are some that were reworked by the Turbinator brothers. I don't recall what exact injectors they started with.Does anyone have the part number for the genuine BOSCH 311 injector nozzles? I believe ProCycle had a thread about the so called "MARINE" injectors probably quite some time ago I believe with this info maybe.
