It's another pick on Pete Day!! Ken, Yes, I did learn something thanks' to you. I must have been misinformed by info off the internet or, come to think about it, another member who doesn't visit with us much anymore.

BTW, I did have to replace my hard line to the carb on the 302. I bought the PCM and did have to do some slight re bending at the carb since the PO put a wedge spacer under it.

I may try to bend the hard tube, it is new and don't want to throw it out.    Second choice would be hvac copper tube, Got to dig out my flair tool and get a new tube bender.   Last will be rubber hose.

Steve,
Here's a link to the pre made hard line. Scott's took me to Overtons search page and all they sell are tubes!!    I 'd stick with the pre made since it's steel. I don't know if the copper would meet the regs. I'm sure Ken would know!

BTW, how are you at making double flares? The line is inverted double flared.

Ken knows that the answer is in the regs and the easier reading ABYC guide.

Try page 52 of the ABYC guide.

Ken,
Still going through the guide but page 52 + covers from the tank to the engine. It states "to the engine" is typically the "fuel pump". So, give me a page hint for the line from the pump to the carb.

Page 52 about 5/8 of the way down the page they cleverly tuck in the fuel pump to carburetor line.

It says

"Metal fuel lines used on the engine, i.e. the fuel line from the fuel pump to the carburetor, may be made of materials other than those listed. This line is usually supplied with the engine".

I have brass on my boat. I think it came directly from PCM a few years back.

The off the shelf tube isn't going to be made for the wedge, original tube is designed to hook up to a carb that is angled back, move it level and its off by 12degrees.   My steel tube is New, I will try to bend it to fit otherwise copper will be second choice and Yes I did read the USGC regs and verified the type. Seamless   annealed copper which is HVAC tube.

Again, how's your double flaring skills?

Thanks Ken. Yup, the statement is tucked in there.

Scott, I like this one, looks well made and will take care of the bending issues plus no need for barb fittings.

Double flair only has one more step outside of a single, whats hard about that especially on copper.   The sierra part doesn't appear to be a double flair. Isnt the double for higher pressure?   got to look it up I guess.

Steve,
Well the last time I made a double, I'm glad I practiced on some extra tubing first. I always find that even with the gauge, getting the proper distance of tubing clamped into the flare tool is the hard part. If you make double enough, it's easy. Do you make them frequently?

Good point on not being hard to do. Just need the correct tool. Yes on the dbl flare for high pressure. Another type uses a single flare but has a "flared sleeve" that mates up with the flared tube. We use that type on the race car a lot because you can tighten and loosen multiple times with out affecting the integrity of the tube flare.   NHRA and other sanctioning bodies allow the use of aluminum fuel lines but prohibits copper.   Don't know bout USCG. Seems to me that I read somewhere that the USCG rules only apply to waters that they govern. Different can of worms.

Need to use approved stuff for the ins company. if anything happens and you have a part that isn't approved then an exclusion in the policy will likely bounce your claim.   If its USCG approved then it is insurance company approved.
I am not aware of a body of water in the US and territorial waters that are not under USCG authority.   They are the feds, trump all local and state.

Probably a smart idea to follow their regs anyway, then you are covered.

Little off topic:    Our Funny Car inlet fuel line from the tank to the pump is Aluminum 3" diameter!!   15 gallons in 5 seconds

Ok.. I am back .. New QFT installed.. on the 78.. runs much better.... but.. it still seems to struggle out of the whole.. could a bad pic valve prevent the secondaries from opening. I also have a lot of slack in the throttle cable.. but the carb is still going wide open..??

Anyone interested in my old 450cfm holley?

Thanks guys

Eric:

If the engine runs well -- except for hole-shot -- I would look at accelerator pump and engine timing. What is your current degrees of advance at idle?

With the accelerator pump, the instant that the throttle linkage moves, the accelerator pump must start to engage. No delay. Also, there are different cam profiles that will modify how the accelerator pump engages: duration, volume, timing, etc:. You may want to watch the video below for some good tips.
