Why not tee into the return line going to the tank along the frame rail?

As of yesterday afternoon everything is good, I'll run it a few more times next week and make some fine tuning adjustments and I believe all will be good.

I've got tweeking to do and more run time, swap injectors back to his, etc... It does sound much better, it seems to have a "spit" and it's both banks, nothing terrible, just not smooth yet...

Maybe, keep in mind I'm winding down my need....

I have all the usual plugged in so they are seen. I use water temp, CPS, all the IP plugs, and lastly the harness has the OBD1 plug and requires a OBD1 ECM...

I'm being told OBD2 can't be done like this, all I'm doing is getting the pump in place so the owner doesn't have to move it, he knows he will need to time it to his pcm... My setup let's things talk enough then I unplug, as long as the pump is right it's a breeze for him and it proves the motor...

Well I don't know what I did but something fixed itself, at least for now, lots more running to come... Timing @ -1.94

Thanks, everything has been disconnected over night, I'll head out and start from scratch and do some checks... A few days ago I did disconnect the cps, when it did start it ran smoothly so I think that means that CPS is bad, I swapped another one and went back to running crappy...

Doing some searching I think I should check the optic sensor and steeper motor to see if they are working.. I'm not a electronic pump person till now, so could someone tell me how to check and maybe replace these items, and every time it throws a relearn error code, I have cleared codes...

This IP was on a motor that failed, the owner says he thinks it was working when it was removed. The prom I'm using is a prom quadstar sent me to use for this testing on my stand. I do have the owners prom I'll swap and try to see if that makes a difference. I could swap a db2 in to prove...

I have a new build on the run stand and I'm having a lot of trouble getting the timing set. Everything I'm using was used a month ago so I know that part works, and I use GMTD on my laptop and have done it before. Now, this time I'm using the customers used IP & injectors, and pmd extension...

You need to look again at bearing clearance, keep bearing clearance at .0025-.0030 inch max.... And I have new takeout valves and springs I'll offer you cheap if you need new valves and such...

I see a lip on the outside edge of the valve, if you're not going to pay a shop for a valve job just clean and run as is...

The contact area on the seat and valve probably have a curve pounded into them from miles, normal. Laping isn't needed or done if a good valve job is done on newer machines, if using a grinder and rocks then a lapping is useful. Post some close up pics of the laping contact patches...

Looks like you're paying for glitterie shinny parts under the truck to me.. good filtering has already been done...
