lifter galley crossover tube with air gap intake?

Ah. Well, that makes more sense...lol.
90° fittings negate most of the benefit, as do holes that are straight down into the galleys. The 45s, with holes drilled on the right angle will be tight to the block and I'm pretty sure that would fit. But, what's done is done. You may want to remove the braided and fittings, and then use some clay to check what room you have. Dual planes are not normally used in applications where that line would be. So you may need to do some playing around to see what exactly will fit.

moper, let me see if i got this right. you should drill at a 45 degree into the lifter galley and then us a 45 degree fitting to make a straight metal line between the two????
