my intake runners are made from 2, 18 inch by 1 1/2 stainless bathroom grab bars, get the exposed screw version, $18.95 each at home depot, I used big block chevy water pump gaskets and a thin coat of black rtv to seal to the heads, took about an hour each runner to get bolt holes located properly,

here is what you need from home depot, 2 glacier bay grab bar, p/n gb10018-21 , and gasket p/n is 30060 fel-pro , available at any auto parts store, and lots of patience fitting, cutting, and grinding, a trip across the wire wheel on my bench grinder gave them the polished look

the flanges are welded completely, smaller tubes probably would make more torque, but as is I can bring mine up between 1500 and 2000 rpm, ease the clutch out and go, I weigh 340, so that is good enough for me, I saw some smaller diameter bars on ebay, looked like the same flange, you might try them and see how it works, I would be curious to know, I used the 1 1/2 for easier hose seal, less transition difference....

It is a reman 740 I got off ebay, I removed choke, Idle solenoid, plugged the high altitude enrichener fitting below fuel inlet, took top off and removed plunger from purge solenoid, cut the coil off purge solenoid and plugged the hole in the threaded part and screwed it back in to stop up that hole, pulled the purge tube fitting and plugged that hole, also used uni link on opposite side from original throttle arm

Here is all the stuff I removed except the plunger and coil from the purge solenoid, and a couple pics of throttle, poor pics but you can see enough to get the idea, I used throttle arm and cable bracket from weber dgav I had from a Jeep project, had to add a small link for cable mount, simple stuff

2 joint system

I just decided that using the stock manifolds was more trouble than it was worth, the smooth mandrel bends and 1 less joint looked better to me, and was definitely better than anything I could fab on my own in the cave, I figured it was worth a shot, so far I couldn't be happier, I may have to do some jetting/tuning to get mpg where I want it, but I am over the major hurdle I think, different strokes for different folks

what size and type of fuel rated hose did you use? The VW manifold spigot is 1 5/8" OD and your runners are 1 1/2". Did you use 1 1/2" fuel hose and stretch it over the spigot? Can`t seem to find 1 5/8" fuel hose listed anywhere.

I could be wrong about it being fuel rated, what I used is Gates stick hose, available at o'reillys, it is commonly used for fuel filler pipe connections on automotive gas tanks, but if you keep the gap between runners and intake very tight it should not cause any problems
