[DeTomaso] Has anyone used the Earls 510ERL oil cooler adapter?

I don't see how you're going to use 3/4 pipe thread in 3/8ths pipe thread ports.

3/8ths is too small for a V8 in my mind.  I'd use / have used 1/2npt on V8's and 
3/8npt on air-cooled VW's.  However this may be more superstition than fact.  
Some guys run 3/8ths on V8's and 1/4 on VW's and maybe doesn't make a practical 
difference.

With this adapter

I used curved metal tube 90 degree push-lok barbs in a tight spot.  Looks sano 
and so far so good.  Big fan of push-lok here.

Not a fan of sandwiches because I want the hottest oil going thru the filter, 
then the cooler.  Not cooler, then filter.  This might also be more a 
superstition than fact.

Might skip the thermostat on a performance application:  restriction, 
complexity/one more thing to fail.  Biggest fear would be getting a big air 
bubble instead of oil when the thermostat opens in the middle of a "race".

Just sayin' ... I could be wrong

That's as good as any, I guess. You'll need two dash-8 45 degree-to-3/4" 
pipe AN fittings to get the braided-steel hoses away from the block so you can 
route to a remote oil cooler or a remote filter (or both). I do not 
recommend 90 degree fittings -ever- due to the restriction to oil flow they 
present, and I definitely do not recommend smaller than 1/2" ID hoses in any 
part 

of any oil system!  Some guys use dash-10 (5/8"ID) fittings & hoses. Earl's 
'3/8-hose' suggestion is courting disaster in a high rpm performance engine! 

Keep the hoses as short as possible and far away from all hot or moving 
parts, bolted down if necessary. With some adapters and straight fittings, you 
may find it will only fit in one (1.0) position due to a block-register boss 
in that area, and it might point the hoses in a bad position. You may need 
to retrieve the flat o-ring seal from an old oil filter to use on the block 
side of the adapter, since some assemblies do not come with anything extra. 
If you find one for $5 or $10 at a flea market or swap meet, check it over 
carefully for pinholes in the (Chinese?) casting, chips in the o-ring areas 
and cracks in the pipe thread bosses. Sure- a TIG welder can fix all of 
them, but that's just more cost. I once had a swap-meet unit that needed FIVE 
TIG welds to operate without leaks. 
FWIW, I run both a Ford/Laminova water-to-oil cooler, an oil thermostat AND 
a remote filter on a 351-C , all supplied by a stock oil pump. D. Quella is 
a Laminova dealer & runs one on his racer. Laminovas are compact, effective 
and small. Plumbed properly, a high-volume or high-pressure pump still 
isn't needed even with these oiling extras. Good luck- J Deryke
