converting 94 to crank driven oil pump

I am converting my 90 (yeah, it has been a while on the back burner not running) to a crank driven oil pump by swapping the front cover to the "intermediate" front cover that is set up for a serpentine belt but still takes a distributor. I am also converting all the accessories to serp belt. Kind of a pain in the ass, but it is going fine. Question, though--the water pump doesn't have a heater return port on it so I am imagining I have to use a Disco lower radiator hose that connects to the heater return and the resevoir. Is this what others have used? Seems like it may be a different shape but I can't tell without buying one. Has anyone done this conversion?

Yes on the Disco hose. Blast from the past!

Thanks Pendy--yeah, it has been down for a while. Couldn't wrench for since you sent the cover and stuff out--First dislocated and separated my left shoulder, then broke my right clavicle and had to have a titanium plate and 9 screws put in. Given the OK to resume Aug 2nd, so finally getting around to it!

I did not know.

Sorry to hear this. May I recomend Asian massage therapy. Think they give a titanium discount.
Kidding aside. Hope the recovery goes good for you. Check in with me if you come up short on parts.

The conversion went pretty well-- a tad involved due to all the bits involved, but I'm sporting about 30psi at idle so am very happy :-). Had to fabricate a alternator mount, still converting the new air con pump for air compressor, and swap out the steering pump which is groaning and should be back in biz!

Just a note on the oil pressure sender and VDO gauge--I had the sender installed on my v-belt set up on the oil pump pressure switch but I noticed that the serprentine belt oil pressure sender hole is too close to the block to physically fit then sender unit. That is why you see several people with hose contraptions up out of that area and mount the sensor remote. I was fortunate to have my front cover off and some time to think about it, but all I did was take an old stock sender, chop off the top and drill it out and tap it for a 90 degree elbow and just connected the sender to that. The only way possible to ge the elbow on, however is to have the front cover off, so if you ever do take your cover off, then put one of these on! I will post some pictures in the near future under the appropriate vdo gauge thread...
