Re: Restoring Rusty
That hose says SAE J30R7. That's just plain old fashioned carburetor fuel hose. Same as GM and others used for carbureted fuel systems through the end of the age of the carburetor. Max running pressure is 50 PSI, intermittent operating pressure is 75 PSI for Continental hose but not all hose meets this spec, burst pressure is 250 PSI. That's for NEW hose.
The SAE has actually downrated J30R7 to use as EVAP hose but it's still just fine for lower pressure non-fuel-injected vehicles. I use it on my ATV, Motorcycle, riding mowers, and other small engines that don't use Vinyl hose. You want an operating envelope cushion to deal with aging. The actual operating pressure envelope can be reduced quite a lot by age especially in higher temperature environments with higher ozone levels like West Coast cities. If your operating pressures are right on the ragged edge of maximum you won't get much life out of it. SAE J30R9 hose is the stuff you want for TBI and TPI fuel systems. It's rated for higher operating and burst pressures and is less vapor permeable than the old J30R7 hose. It's what GM originally used on the TBI and TPI fuel injection systems before they went to Vinyl fuel lines in the mid 90's. My first choice in clamps are constant tension spring band clamps that everyone seems to hate. They maintain constant tension over a wide temp range without over tensioning and smashing plastic hose barbs or crushing the hose itself and loosening up like worm clamps seem to do. German Fuel Injection clamps are a close second choice. If you're an SAE member this is the link to the J30 fuel hose standards. It's some pretty dry reading. https://www.sae.org/standards/content/j30_199806/ |
Re: Restoring Rusty
I believe that AC Delco filter uses a special GM Fuel line fittings. The end is straight with a ring crimped into the tube that the ferrule rests against with a shoulder for the O-ring.
This guy shows how to make GM Fuel Line crimps and Jiffy Tite transmission & oil cooler line crimps. |

You all won't believe this, so I button everything up and turn the key to prime the fuel pump and I hear a gush of fuel hit the pavement, I'm like Noooo can't be
Yup, a fourth line has failed on me, this time the high pressure hose that runs from the fuel tank to the fuel filter, and I did not touch this line!!! It is so UNBELIEVABLE I made a video for it, so avoid this AMAZON steel braided hose at all costs https://www.youtube.com/watch?v=dwd68TfculU |
Re: Restoring Rusty
SAE J30R14 is the new J30R7. It's an updated low pressure fuel hose spec with the lower vapor permeability of J30R9 and better ethanol breakdown resistance in the spec with the lower operating and burst pressures of the J30R7 hose. Most manufacturers already met or exceeded the ethanol resistance spec in their J30R7 offerings but not the vapor permeability ratings.
The stuff you want on the pressure side is still SAE J30R9. Gates used to have a comparison tool but I can't find it. |

Re: Restoring Rusty
That is definitely unbelievable! Hate to say it, but if you haven't already I'd replace every last bit of that braided hose on the truck. That could have had a VERY bad ending!

Re: Restoring Rusty
Sure am.
https://www.underhoodservice.com/cor...-installation/ J30 is the SAE fuel line standard with R numbers for specific types.
Ignore the comment in that article about using J30R9 fuel hose for oil. J30R9 doesn't have the temperature rating for an oil or transmission cooler. It might work for cold oil but not for an oil or transmission cooler at operating temp. SAE J1019 hose is actually designed for that job. |

Re: Restoring Rusty
Yeah. That's one of the reasons I educate myself before getting stuff from the parts guys.
They mean well but they'll also offer you fuel hose for transmission coolers and regular fuel hose for in tank fuel pumps. You might want to get the spec sheet for the exact hose you have. Manufacturers can and often do exceed minimum specs. |

so I wrote to the seller on Amazon since I bought three hoses from them over the last two years, and I sent them pics of my hose failures and the link to this video, I was not rude, I was honestly concerned for other peoples safety, and they kindly replied and promised a full refund

Re: Restoring Rusty
"Hope nobody hurts"..
I used junkyard factory hard lines with a small piece of rubber at the sender with double FI clamps. |
Re: Restoring Rusty
If you bead the end of the tube you don't need to double clamp it.
The ATS Parker Beading Tools are darn nice but the price is pretty dear. Here they are FWIW I have seen similar bead forming tools made from modified pipe cutters. Depends on your tooling availability and skill set. The Earls tube beading tools work fine for a few tubes. |

For the part-time/shade-tree builders, brass compression fittings also work as an easy way to get it done on steel tubing w/o a bead forming tool. Put a ferrule + the male/female portions of a brass fitting together on the tube. Tighten the male/female portions to locate & 'crimp' the ferrule in place. Loosen the male/female portions. Then grind/cut the female portion off as needed using an angle grinder. The crimped ferrule is left on the tube & the hose can be forced over it w/a single worm gear clamp to keep it firmly in place. |
Re: Restoring Rusty
dang...that could have been disastrous

Re: Restoring Rusty
I always just do a bubble flare with a normal cheap flaring tool. I even did a video on it a few weeks ago when I made new trans lines.

Interesting idea using ferrules as a small tube bead. I stay far away from worm clamps on hoses smaller than 1". I use constant tension spring clamps and fuel injection clamps for smaller hoses. I'm moving away from worm clamps to spring clamps on larger stuff like radiator hoses at this point. Toyota has been using them for a couple decades and they don't leak. I hate the locations the thoughtless line workers tend to put the ears at the factory, and I'm not the only one that does, but they can be moved to a location that's accessible so they work for fine the rest of the life of the vehicle. |

Gentlemen does this "brand new" Corvette Servo look brand new to you all, ladies as well
by the way the new large C clip was so rusted I ended up re using my old one (not shown in pics) |

Re: Restoring Rusty
Why do you beat yourself up by ordering from Amazon. I like my parts from a tranny shop or engine shop. I,m sure you have your reason,s but I got tired of that game. Getting old so don,t like to do it more than once but that doesn,t work sometimes either .

so the truck sat in the garage for 2 or 3 weeks while I slayed it in my '54 and painted our perfectly fine oak kitchen cabinets... white! [pronounced: no time to work on the truck(s)]
and the texter side front tire went pretty much all the way flat... on the bottom I took it off rolled it around and usually I can spot a nail or a screw somewheres in the tread section right quick, but nothing this time, checked the valve and it was tight so after coating it in Windex and no bubbles, I took it to our vegan environmentally friendly fluid dynamics station, and still couldn't see any bubbles, what gives? is my Ex messing with me again !!! ha ha |

I've had more than one that when the cap was tightened all the way tight, it would inexplicably slightly compress the stem allowing air to purge. Different caps solved the issue. If you can't determine anything else, it might be worth dbl checking. |

I can do an all Black Vinyl. They are fully restored. That’s the frame, tracks and all the hardware. I would highly doubt that upholstery shop would have touched your frame or tracks. They would have charged you $600-$650 to install a cover, and that’s it. I also replace any broken springs. I don’t just stick a block of foam in there, like I have seen done so many times. |

are you saying $350 for a seat or just for shipping, sorry don't mean to be difficult that just sounds amazeballz, and yes shops quoted me $500/$600 for just a vinyl cover but they sow/make it not one that I would buy first |
