Gettin ready to order fuel line hose and fittings. Is there a fuel hose that isn’t braided and a pain in the butt to work with that works with fuel injection and doesn’t cost my first born child? I’m struggling with what freaking hose and fittings are gonna cost me.

Fuel injection hose that doesn’t suck

I have used earls vapor guard hose and fittings for the past two years and have been happy with it. The fittings are super easy. My efi system runs at 58psi.

Earl's Vapor Guard EFI Hose
Modern fuels are the enemy of traditional rubber hose (including steel-braided hose) causing deterioration. Rubber hose must be inspected and replaced frequently to eliminate the safety hazards associated with fuel vapors and leakage that occurs as the traditional rubber liner deteriorates. Use...

That’s a lot more reasonable pricing. What did you do to adapt the sending unit? Or just run the hose over the barn and clamp it?
Well, I just dropped the big bucks on this fuel pump/sending unit, for my saddle tank, but I'm sure Holley makes a similar unit for the Blazer tank. The cool thing is you can reuse the hard lines as long as you clamp the hose with the vapor guard clamps.

Good to know. Thanks.
Nice that they include the hydramat so you can run an un-baffled tank. Unfortunately they don't seem to offer the same for the K5 tanks.Well, I just dropped the big bucks on this fuel pump/sending unit, for my saddle tank, but I'm sure Holley makes a similar unit for the Blazer tank.

I’ve been using raceflux vition hose and fittings. It’s black braided but not like the dreaded stainless ptfe lined hose. Super easy compared. I think they are hotrodfuelhose.com
The nylon summit brand hose is pretty easy to work with. I ran that hose with their fittings on the 84. IIRC I used earls fittings for the metric to AN adapters at the K5 sending unit.

TBI pressure or high pressure?
On my Dodge (TBI) I ran parts store ethanol rated hose to steel lines I bent myself then back to hose where it hooks to the throttle body, it’s not fancy to look at but it gets the job done. On the Chevy I run Eaton fittings from NAPA -8 on my fuel cell, then to rubber hose to the steel lines.

Fuel injected.
For what you want to do the Earls Vapor Guard would be perfect because it's cheaper and easier to work with. I dont recommend running it the whole length, but some people do. You can get hose ends for it to screw to a AN fitting so you can use it with the AN adaptors for the stock o-ring fuel lines. Or you could run some hard brake line and use the Earls hose clamps. Just make sure it has a smooth barb, you aren't supposed to use any sharp barbs with the Vapor Guard hose.
I have been using the Gates high pressure Green Stripe hose from NAPA. Its rated for ethanol and has been holding up really well for the last 4/5 years.
That’s the stuff I used, made my own lines from steel brake line.
Not opposed to the brake line idea. Just never done it before. Probably be a lot cheaper than getting 20’ of vapor guard hose. Flex line from tank to frame and then frame to engine. Put a fuel filter somewhere in the middle.
Essentially all the early TBI systems were was brake line with rubber hose, the factory added fancy crimps but if you carefully cut those off it’s just rubber with a hose barb.
Our ethenol fuel needs stainless or plastic.
See what Inline tube has to offer.
20 years ago I wouldn't hesitate to use 3/8 and 5/16 ths steel tubing to make fuel lines, now not so much. Recently acquired a stainless line for my Early Bronco, pump to carb. With added saddle tank that truck has plastic fuel lines, to selector valve.

I assume you are talking about pickups? The K5's and 'Burbs were all braided flex line with the GM o-ring connections. As I recall the flex steel lines are teflon lined (never cut one open myself), so should be resistant to ethanol.
Yeah, most of my fuel lines are from a TBI K5, like you describe, so been in service for over 30 years. AFAIK always some ethanol in them. The only problem I've had was with aftermarket hose (from the TBI lines at the frame over to the TPI rails) that grew a leak after about 15 years. That was some teflon hose with stainless braid on it from a local hose shop. Couldn't tell you a brand.
