78/79 ski-tique rod knocking

another silly question: On the fuel pump,.. which hole(front/rear) is the inlet and which is the outlet? (I took pictures of all the stuff I knew I'd need visual reference on and forgot to on the simple things,... lol)

K,.. preesh

Hey Pete,.. where'd you say I can get one of those? There was some site or something that sells them for like $20 or so but I forgot where it was.

You got it, that's the right fuel line... or should be if you have a stockish intake manifold. On Holleys, the gas line goes in the front towards the port side.

JJ,
I bought one from Skidim for my 302. Since it's gots a wedge plate under the carb, some tweaking was neded but it worked. The alternate is to use pre flared brake line and bend one yourself.

Ive heard that its not a good idea to use steel braded line with an fittings,.. why is that?

To my knowledge, they are not USCG rated.

CG rating is important, but another concern is that the flares may be different. I can't remember which is which, but automotive and aircraft use different flares, one is 45 Degrees, and the other is 37.5 degrees.   using the wrong flare will make the fitting leak

Didn't we recently see AN fittings on a metallic blue Ford?

Speaking as a guy who sets his boat on fire every now and then... regardless of regulation you do need to be a little careful in your fuel line selection on a boat. The specifically what is needed between an engine mounted fuel pump is something abrasion resistant (to avoid wearing through either by vibration over time or by contact with a rotating pulley or belt) has positive stop stress relieved attachments (ie not a non flared compression fitting on a hard line that could be slowly and imperceptably pulling out, or a soft line with a clamp and a barb fitting because it also could blow out under pressure suddenly and it could through fatique crack over time) and something that has a high enough melting temp to allow you enough time to swim away should you have a small thermal event under the motor box.

A high quality rubber hose with stainless steel braiding and AN fittings properly used meets all these actual requirements. But there are no markings on stainless braided lines that seperate the cheap low melting point rubber junk from the high qualily stuff that will give you enough time to swim away. That is more an issue for the coast guard because they cannot easily check than it is for you who can check the specs of the material you buy.

and dont be a dummy and put teflon tape on the threads, flares do the sealing not the threads, I dont own any teflon tape that *************** gets everwhere so i use pipe dope, the only place you should see dope or teflon tape is on a NPT National pipe thread.
just brought that up cause i always see teflon tape hanging off the carb fitting
