Can these pipes be removed without dropping the gas tank? And can the SS
pipes be installed as well that way? Engine and tranny are out, and I�m
prepping for the conversion.

 

The pipes in my �85 are not rusty, but one of them is flattened for about 4�
to an oval that�s �� by 2�, rather than the 1 �� original diameter. One
surprise after another with these old vans.  A quick calculation says that�s
about a 0.8 sq. in. area for coolant flow vs. the round 2.4 sq. in. area.
Yikes. Never had an overheating issue, but with my Subaru conversion
investment I�m going to junk these pipes.

 

What�s easiest to install, the two piece or full length pipes? I�m thinking
the full length pipes are better without the extra hose connection, but I
really don�t want to drop that tank (again). 

 

Thanks!
