Hard line 3/8 fuel pump to carb?
Is SS the best material to use from mechanical fuel pump to carb? 3/8 is what I want to use. What is the best routing to go? I assume keeping as far from the engine as possible? I would of course double flare all ends. Need some input. Thanks folks!

That reminds me. We originally ordered a replacement from Inline tube and it wasn't even close to fitting my 100% stock setup. Called them up and they said that I must be mistaken because it's the right one for the '66 Toronado. Well, like I said it wasn't even close. Waste of time talking to those guys. Just made a new one myself and saved the headache.

I just used regular old steel fuel line. Practiced on a a few scrap bits first.......Bent it up and double flared it. It's less than 10psi so you know....it's not a spaceship.

I get a plan in place.

Cool car though! I just looked it up and I've never seen one before. Very neat car!

I'm no expert or anything. I just used a coat hangar to make myself a little map to follow and used a cheap tube bender to bend it up. Gotta get the fittings on there before the tube ends get too bent to install them........then flare the ends and then make the final bends at the end. If it doesn't work out, cut yourself another piece and give er another go.

I think that looks really good. Just keep about a 1/2" clearance from the engine so that you don't risk any chafing and I'd call 'er good! Double check it for leaks as well.
Some weird looking fittings on that thing, is it stock?

Nope this is just temporary, they’re just compression brass fittings, not even tightened up, they will NOT be used for the final setup, this is was just to keep things in place until my 3/8 line and fittings show up. Don’t worry, I’ll double flare the connections properly.

In a word, no. At least not in my experience. The original hard line from the fuel pump to the carb was not stainless steel. Stainless looks nice and will certainly last forever, but keep in mind one thing. Stainless steel is HARDER than the OEM steel. In order for a seal to be made at the various fittings, the flared end has to deform slightly as it is tightened to fill in all of the microscopic gaps. This is not an issue for OEM steel, but it can be an issue for stainless. I actually read about this somewhere.
I replaced the fuel line on my '67 Delta 88 with a 425 engine with stainless steel, and it was difficult to get the fittings to seal. I got the line from Inline Tube, and it was pre-bent to fit my application. I'd tighten the fittings at each end to what seemed like a good tightness, start the engine, and I'd get leaks. Stop the engine, tighten some more, and restart the engine. Still leaks. I eventually ended up making the fittings VERY tight, pretty much uncomfortably so. But the fittings did ultimately seal, and I had no further problems. But if I had to do it over again, I would definitely get the OEM steel and save some money in the process.

This is a useful thread for me, as I am still in the process of worrying my ILT-ordered custom-bent fuel line into place. It's about an inch out in places, which is just enough to require use of a bending tool, so I'm getting psyched to try doing that without cracking it like I did the last one.
Then there's the matter of getting the fittings clocked correctly so the angles allow everything to be buttoned up.
Best of luck to OP!

Not sure what the original was, I’ve had rubber line with a metal filter inline l. It’s always been with rubber lines when my gramps gave it to me after buying it from an old woman in the 90’s. Would aluminum work? Not sure which is easiest to work with. It’s only from the mechanical fuel pump to glass bowl filter to carb.

Another reason I'd go with original steel is alluded to by BangScreech. Even though the line I ordered was pre-bent to fit, a little tweaking was still needed to get everything to line up just right. It is easier to bend the OEM steel than it is the stainless, even just a little bit.

Unless you have a really high end tubing bender I’d stick to softer metal. I have a decent 5/16” 3/8” bender and I still have trouble bending Nicole/copper lines into anything past 45 degrees. I like the idea of buying a pre-bent versions. I’ll have to look into that for my Jeep.
