just pulled the intake off. then pulled off the hose at the ip and turned the lp on. and i got good flow all the way to the ip.... i pulled the nipple for the hose off and no screen.. is it further inside or is there not one on this pump. and when i went to take that nipple off the whole back part moved, that the nipple is fastened to... is that ok or is that for timing......
I also grabbed the numbers off the pump.

If there is no screen,then it can't be plugged-been too long since I had one of those pumps apart to remember for sure.

If fuel has made it that far,your trouble would almost have to be a timing chain/gear problem or the key in the IP drive flange must be sheared or the shaft could have broken inside the IP?

Did you check for any return line restrictions or blockage yet?

I had troubles bleeding my injection pump and lines so what I did was put an air nozzle on my main return line that goes back to the tank and put about 10 psi through it and it sent fuel to everything.

also i am putting my 6.5 heads and turbo on my 6.2. is there clearance problems with this setup. there heath heads the originals crack a while back. do you have any advice.

A 6.2 and 6.5 short block are the same engine except for bore size,no issues with the heads.

Get ARP heads studs that are usually listed for 6.2 and follow the instructions on them to the letter,also if the heads have been resurfaced you would do well to use +.010 head gaskets usually to maintain the compression rating as stock.
With a 6.2 short block the problem is less pronounced so standard head gaskets would likely be ok,I would have to do some calculations to be certain though.

whats the best place to get injector lines from.

IIRC the 6.5 injectors must use the 6.5 lines?

Ebay is as good a place as any for lines.

Just found these,might be what you need?

on my 6.2 i decided to just run the turbo and the 6.5 manifold and leave the head swap for another day. do i still need the vacuum pump. i have a turbo master from heath. the 6.5 always had the tm, idk what else the pump does?

depends if you have a S or F vin engine,the F vin only need vacuum for the wastegate,but the wastegate solenoid must still be connected to the wire harness to prevent codes unless the ECM is reflashed for the turbo master.

The S vin required vacuum for the EGR.

so if im running the 1991 6.2 i shouldnt need it then.
