Noticed while priming that spins faster after couple seconds cranking (oil pressure starts up). Would wear be improved by use of accumulator/lube prime pump or could I just keep shut off solenoid off until I see oil pressure (starts first compression anyway so still using single battery).

Anyone? That's crazy or don't worry @ it, or ????

You are getting low pressure/High volume on the IDI engine. Some have added accumulator (way in the past) but you should be fine.

Is it needed? No, there seems to be a pretty solid track record of IDI longevity when taken care of. Would it help? Absolutely.

I've seen one or two 6.2/6.5 guys do it, none on a 6.9/7.3 yet.
If going off the factory "gauge," get a real gauge and compare.

I have a real gauge and video today it sat on zero until she started (cranking did not speed up like day before). Overnight @ 45F and yesterday @ 60F so maybe should change oil to 10-30 and try again. Don't remember whether gauge pressure or electric but will find out, maybe capillary tube slows response.

I ran Rotella 10w30 for the last two winters over here in NY, just because I got 5gal on sale at wallyworld. Didn't seem to make any difference really. IIRC the spec is SAE30 in winter so you should be safe.

I agree with Jasper though, I'd run the 5w40 as long as you don't find that your engine drinks it like water. I thought about it but didn't feel like spending the extra money cuz I'm cheap lol.

I haven't installed one. But an accumulator would be nice for a turbo engine. Not for the start-up, but the engine shut-down. Save on the turbo. I try to idle the engine a bit before shut-down. Just can't justify the extra expense.

Same here, cheapest 3 qt Accusump @ $220 on fleabay so thought to try just holding FSO closed until cranking speeds up (but no speed up). Wanted to change oil/filter anyway so will try 5-30 and try to drain oil cooler / flush pan also. Accumulator better since would work for both shut down and start up.

I just thought they were cool. With accumulator (in my head) you would want 1 for pre lube and a separate 1 for shut down ... you could just put this pump on a timer + momentary switch and get both ... + no 3qt accumulator to find space for.

Your right, was planning on one pump or accumulator for start/stop (+ have another job possible for pump), secret until it works:D

From above....

Check this out:

---------------------

I have some of these. Used them as transfer pumps. Nice little gear pump.

Don't like to run em continuous...they run a bit hot for my liking. They use 3/8 inch fittings. The home Depot fittings fit.

I think $300 is a bit pricey though.

Try here...

$100 ballpark. By the time you throw shipping in.

Betcha this is where they get 'em.

There are several vendors selling the same pump from what I see. Different pricing for pump and shipping.

I have done a lot of business through AliExpress. Most of the industrial stuff has been on the up and up, but most of the cheap fashion stuff meant for retail resell has been a disappointment to me.
