Here's how I've been making it for several years now (i think i derived this from the listing at cocktaildb.com):

1.5 oz light rum
1.5 oz dark rum
1/2 oz lime juice
2-4 oz passionfruit juice, depending on the source/strength. (fresh passion fruit has a marvelous perfume but is extremely tart; sometime I use one of the spanish brands or even welch's)
2 tsp grenadine (mainly for color)
1 oz simple syrup (adjust up or down to taste).

serve in a tall ice-filled glass with a straw, garnish with cherry, orange slice.

I have no idea why the Pat O's are so red. food coloring I guess.
