Ebay fuel lines

[NOSLO2PT0]

I guess this would go here, since it’s fuel related. Recently, Marty started a thread regarding fuel line size and lean issues with BIG injectors. Got me thinking about upgrading my fuel system. Do you guys trust those eBay fuel line kits for $40-50, that include like 10’ of line and all those fittings? Hell, the fittings alone they provide would cost more than that if you bought name brand (Earls, Russell, etc).

What’s everyone’s take on the eBay fuel line kits? My last car had name brand -6AN from the tank to the rail, but I was only running 1600cc injectors. New car still has all stock lines, but running 2150’s.

No, I don't trust an item in which the only consideration in engineering was to find the absolute lowest price possible to produce it. The stock fuel line is good for 600+ WHP. Replace them when you run into fuel issues, and don't replace them with garbage that puts safety at risk.

I can’t stand eBay. You can never trust them even if it’s from a dealership. Received my jeep front emblem today and this is what I got…just the package for $70

Is that an empty package? Just file a claim, ebay will take care of you.

Yup no emblem, just the package. I did file a claim so they better get on it . Just annoying I have to deal with it. Either the guy that packaged it stole it or it fell out.

When youre buying those kits, youre essentially buying cheap China made products. Most of those listed items you see are bought in bulk for dirt cheap directly from the manufacturer in China..and resold on Ebay/Amazon for a profit. Just like any other business model...with the horrible risky quality getting added to it. If it were any other item, sure. Youre talking FUEL lines here. I wouldn't cheap out. Even the "branded" fittings on Amazon/Ebay are cheap China parts that they pay a little extra to have a logo stamped on. Im not talking about the big names like Russell or Earls.

Here ya go.

I have a kit of the -10s and -12 from amazon I bought 5 or 6 years ago and needed quickly. I use them on my catch can, figured since it's under no real pressure it would be fine to use cheap ones. The vacuum leak I had from every fitting was so bad I had to just vent my -12 suction hose to atmosphere for my trip because the MAF was going crazy with it plumbed into the intake. I'd avoid unless you like roasting marshmallows on the side of the road.

I always try to consider the consequences of failure when evaluating these sorts of things. If you're ordering some cheaper interior panel mounting clips, and they fail, you get an annoying rattle that you can fix when you have time. If you install substandard fuel line and it fails (especially under the hood!) ....
You get the point. I will say that I don't believe all Chinese products are crap, back in the 1970's that's exactly the way that most folks talked about things made in Japan! Good thing DSM is from Illinois.
I still do order some things off ebay, and others I get only from reputable vendors like JNZ, RTM, STM, E-PSI, and so forth.

A little sneaky tip. Some of those vendors sell the same stuff on Ebay for cheaper

You do know that the DSM was just assembled in IL, while all the parts actually were made in Japan

What nonsense. I feel like a broken record on this but I'll post it again. I maxed out a 37r with boost into the 50s using completely stock fuel lines, filter, rail, a single in-tank pump, a bolt on afpr, and 2150s. This was with E85 also. The car behaved like stock and had zero issues. There is absolutely zero reason for aftermarket lines or anything more unless you're going for HP into the 800s using corn or even more with gas.

What I found on the Ebay fuel lines (like Vibrant but NOT) is that they aren't exacly sized. I sure didn't trust it to hold 40+ lbs of fuel pressure at the fittings but we did use it as low pressure line on my sons 86 Z28. I have a Holley Blue pump mounted in the back and we run that line up to the carb, but only at 7lbs.

I think the rear seats were made in the midwest...
Yes, I was attempting some poor humor. My point is that Japanese products came to be very well respected, and at some point Chinese products will too. I mean the iphone in my hand right now was pretty much manufactured there. I do agree that one has to be cautious with ebay offerings.

Did you do this on a stock style fuel filter with oem feed line and banjo bolt to the rail, or at least upgrade to a -6AN filter/feed line to the rail?

 

[Stapl3]

Stock fuel filter from the local auto store.

I lined the stock banjo bolt up as per a faq many years ago and drilled out the hole a hair. Later seeking more flow I replaced it with a fitting and saw no change and regret doing it.

It's your car and do absolutely what you want and definitely experiment. But I'm telling you based on first hand experience the stock stuff is good for 99.9% of us.

If there was any modification here I wish I had done, is to delete the fuel filter entirely. Run a new line from the hardline going to the fuel filter directly to the rail inlet.

 

[NOSLO2PT0]

No fuel filter at all? Trust the filter on the pump 100%?

The only reason I asked this question/contemplated the upgrade was due to a previous post regarding a lean spot as boost comes on when using stock lines and very large injectors. Maybe I’ll just keep everything stock for now as my ultimate goal is only in the 700whp range

 

[jed344]

No cheap lines or fittings here. Fuel delivery is not the place to cut corners.

What dyno and what was the car trapping in the 1/4. I see claims like this then the cars trap 140mph. Was fuel pressure being logged? I am not aware of a in tank pump that can come close to supplying that amount of fuel at 90+ psi fuel pressure.

 

[TCB91GSX]

I'm still trying to figure out why this is even a thread.. Do it right or don't do it at all.

@Stapl3 has been a member here for over 15 years. I seriously doubt he'd waste his time making exaggerated claims about maxing out a 37r with stock fuel lines and a single in-tank pump just to try and prevent someone from attempting to use cheap Chinese fuel lines and fittings. Is a timeslip truly necessary for him to make that point in this type of thread? Are you making the point that a larger fuel line is necessary at power levels below 800hp on E85? Since the OP didn't specify the goals I guess we'd have to clarify that for relevance.

Just want to make sure we're not going off on a tangent that isn't even useful for what's being discussed.

My take - be careful with the fuel system. I ran braided lines and fittings (well known brands) on my set up when I was taking the 1g out to the road course regularly. I noticed fuel leaks in the engine bay on a few occasions and was VERY lucky the car didn't catch fire.

When considering where to take short cuts on cheap parts, you'll want to weigh the risks if those parts were to fail. Things like the fuel system and the suspension and steering systems could have catastrophic consequences. In some cases it doesn't matter that much, but the fuel system probably wouldn't be where I'd be looking to cut corners on cheaper parts. Some might not agree, and that's completely fine. It all comes down to how you assess risk for yourself.

 

[jed344]

My question likely does not help OP. I was asking because in my 12+ years being here I have been on different dyno’s and it can be miss leading i feel as 800whp on a dynocom vs a mustang dyno is very different and can give impressions that those numbers are the norm.

I get that, and that is definitely true, I just don't know that it's super relevant in this discussion or the point he was trying to make, since he wasn't claiming he made 800hp with stock fuel lines, only that he maxed out the 37r. He referenced 800hp only as the level where an upgraded fuel line might be necessary if using E85, or higher if running gasoline. I guess we'd need to know what the OP's goals are so we can see if he'd even need a larger fuel supply line at all.

Again, not a big deal, just don't want people wasting their time debating something that isn't even the focus of the thread.

 

[NOSLO2PT0]

Ultimately, I’ll be on a 63mm turbo, hoping to be around 700whp. Car is going through stages of power levels. Trying to crawl now (14b), then walk (FP Green), then run (BW S363sxe).

i just wanted to make sure the fuel system will be up to the task. Only want to build it once

The car has never been on a dyno or at the track. I did the tuning myself with 3rd and 4th gear pulls on the highway. 40psi base fuel pressure, rising into the low 90s obviously. I tried it at 30psi base fuel once, but behavior changed for the worse and the duty cycle on the injectors was very high. Pump is a modified Walbro 450 with a BAP. I don't know or care what power it makes or time it would run. I'm only interested in trolling around on the street and doing 2nd and 3rd gear pulls. It's undefeated and has pulled on some crazy stuff. The parts I used are what I used, believe what I'm saying or not and any doubt I guess I'll take as a compliment, but I know what I did with the parts I listed and have nothing to hide or lie about.

 

[Stapl3]

No fuel filter at all? Trust the filter on the pump 100%?

Sure. That's a gamble I'd take. How many cars out there are running around with stock fuel filters on them and 100k plus miles? How dirty is fuel really? The stock filter is just a restriction to flow in my eyes and I would be curious to see what happens if it's gone. Even if it's a 5% increase that's big time when pushing the limits of stuff. And I know I pushed the limit of the pump. There was no more to get out of it. I really don't think I even hit the limit of the lines now that I think of it.
