Ok I can't find that pic to fix the twisted fuel line. And on those loosen exhaust pics you seen, what are those parts called, how big are the bolts, and do they have gaskets?

sorry didnt add the link , they`re called flanges and I think thers gaskets. The auto parts store sohuld be able to help with and the bolt size heres the link https://blazerforum.com/forum/2nd-ge...-filter-91472/

Ok I bought a straight pipe to temporarily replace the cat converter. The measuring tape pics are the measurements of the gap from the missing cat. The pipe I bought is 18" long and the holes are 2 1/2". The gap under my truck where the cat used to be is 14 1/2 and the pipe hole is 2 1/2. Is the pipe I bought too long? And should I have gotten a size smaller hole to slide it in easily? Also I bought bolt clamps to clamp it down.

cut the pipe with a hacksaw. you will need to buy adapters
to connnect them

I need to cut the pipe? Is it too long? What about the holes is that enough to slide it in my exhaust pipes? And what adapters? The bolt down clamps won't work?

if the new pipe slides over the old you should be good. length and everything. if they are the exact same size you will need adapters

What are the bolts to the flange that connect the exhaust pipe and exhaust manifold? Couldn't I just pull 6 good ones from a newer car or truck at a salvage yard?

I would get new ones from an auto parts store or hardware store

Do they have to be those exact bolts with the springs or just a bolt and nut ?
