I've been looking at pictures of the hoses and didn't notice any interference. I still have just a bare frame yet. Is there a picture of the subframe bolt somewhere that would show me the interference? Thanks for pointing this out, that's why I asked
The bolt head isn't flush, but it does occupy less space than a hex head would. Also less edges to rub against the hose.Is the assumption the bolt head will be flush with the bottom of the subframe? I believe at least one person who has assembled the subframe using the supplied carriage bolt has stated it does not fit all the way into the sleeved hole? If this is the case, there may be less clearance than a standard hex head bolt. Careful test fitting is required to check this measurement before committing to a mod that would be very difficult to reverse.
The barb and hose are considerably smaller in diameter than the AN hose connection.And how are you going to get around the subframe bolt that wants to occupy the same space as your hose barbs?
The only problem I see is that the welded hose barb will sit directly under the subframe bolt. You will either need to use Ross's idea so the bolt goes in from the top, or you will need to make the barb removable.I just purchased a piece of 1" black pipe and I plan to machine hose barbs with a lathe that will be welded in place. The pipe OD is .010" or so larger than the tube ID so not much needs to be removed. I thought I'd turn down just enough of the pipe to insert 1/2" into the tube. I'll then machine a suitable barb to fit the hose on the other end of the piece of pipe. Before I move ahead with this, does anyone see any problems I'm overlooking?
#KLMMOTORAPORTS (Ken) has some good pics and discusses this a bit in his build log.Those of you who went 16/20 AN line, can you help me figure out what fittings and direction I should go? I've sort of come to realize my first plan of attack isn't going to work (alumaweld bungs onto everything and go from there). I saw there are some 16AN to 1.5" Radiator adapters and I guess I'll go that route but I didn't want to overcomplicate things.
I know 16 is smaller than desirable, especially considering 20 is basically perfect, but I couldn't find any 20 line that wasn't a billion dollars.
