Hi Guys;
I've been away at tech school for a few months and am just beginning
to get
back to work on my engine.
%%
Wondered where you were!! SNIP
Can somebody out there tell me if this
is just a mount for a filler cap or if it is for a pressure cap?
%%
Both. It's the highest point in the system on the car, and it is also a pressure cap as well. The plastic bit sits on a flat flange. They take the same size caps as most of the late model cars with thin radiators.
Can I
also get the dimensions of it with & without the cap.

I'll see what I can rustle up at work tomorrow morning. I think I have a complete '89 pump sitting on the shelf somewhere that I can measue, unless someone comes up with the measurements sooner.
The "coolantheadertank" pics show how it will be mounted & the
"coolant
recovery bottle" pic is an old snowmobile coolant tank modified. Side
port on this tank has been plugged and bottom port has been modified
to accept a 3/8 hose.
Comments, criticism are welcome, but I'd really like the info on the
filler
neck thingy, so I can order one tomorrow if it is appropriate.

Only comment I can make is that I can see a stress fracture coming to an engine cowl near you REAL SOON where you have welded the pipes onto the evap cores. You could end up with glycol all over your screen.. I'd hate to see you cook a motor. I just couldn't stand it then got blamed on the EWP by "you know who"!!

The bracing looks a bit flimsy, but it's hard to tell from the pix.. Make sure that the evap cores are well supported and gusseted, preferably on rubber. Make sure the EWP is firmly mounted as well. Don't let it just dangle.
%%
You will get ALL sorts of vibration harmonics from the evap cores as they cop a beating from the prop blast. As it stands, I can see one of those harmonics will be the natural frequency of that piece of drilled out angle bracket suppoting them. I can see them in my mind's eye flapping like wings!
I%%
would prefer to have short spiggots (just like a radiator) on each, and a T piece in the middle , all connected with flexible hose. If you really wanted to be flash you could use Wiggins style couplings, but WHATEVER you do, the water lines MUST be flexible.
%%
Apart form that, all looks good!
Cheers mate,
Leon
