Com' On PO - Dangerous Fuel Lines
2 Attachment(s)
The PO decided to run the rubber fuel line from the carb to passengers side of the motor, run it back behind the motor, to the frame rail and then to the fuel pump. The lines were SUPER cracked (see pics) and very dangerous so I reran the lines. I angled the fuel pump connection up and ran the fuel line infront of the motor.
QUESION: Is the way I ran it a bad idea? I want to make sure the heat of the motor isn't going to hurt the fuel lines. What do you guys think?? |
Re: Com' On PO - Dangerous Fuel Lines
I would have ran a metal line myself. Not sure how safe the rubber line is.

Re: Com' On PO - Dangerous Fuel Lines
the rubber lines are fine, not perfect but fine.
thousands of street rods drive everydya like ho you have it. but in the end id be happier with gettin a tube bender and running some nice steel lines, but that's just me. |
Re: Com' On PO - Dangerous Fuel Lines
take the time to run metal, it's simply safer. If you must use rubber, I would not allow the line or filter to rest on the water pump (or anything that will get hot).

Re: Com' On PO - Dangerous Fuel Lines
that method would get you kicked out of NSRA or just about any other sanctioned car show or event. I believe the rule is no more than 6" of flexible fuel line per vehicle.

Re: Com' On PO - Dangerous Fuel Lines
the rubber lines are just fine until they cause your truck to burn to the ground

Re: Com' On PO - Dangerous Fuel Lines
Point taken guys, I will work on getting metal lines going. I was hesitant since I haven't done that before. Thank God it didn't already have issues, I bet I pulled 4 feet of hose and a plastic filter. Thanks for the comments everyone.

Re: Com' On PO - Dangerous Fuel Lines
I don't think it's a good idea to run the lines right next to the alternator and wiring

I would have used an fittings and line. Best lines for fuel pump to carburetor imo.

Re: Com' On PO - Dangerous Fuel Lines
If you have more than about 6 inches of rubber fuel in line in the ENTIRE truck you are asking for trouble. There are only two pieces needed: a short flex segment where it goes from cab to frame and a second one where it goes frame to pump. That much rubber may not even be legal for all I know, but would never pass a safety inspection. And it wouldn't be allowed near an NHRA track (not that you likely care about that). So now that everyone has told you steel lines:
You can buy pre-bent lines for most of it. I enjoy making my own lines, and if you stick to the copper-lines mild steel stuff it's even fun and can be done with a hand-tool. Stainless is WAY harder, don't try it your first time. |

I have high pressure rubber FI line from my tank to motor, probably 18 feet of it. And i have zero worries or concerns |

not only is it a fire hazard for your truck, I'd hate to have my vehicle next to yours if it lights up. Park it in your attached garage and you loose your house as well. Fire=BAD. Do everything to avoid it |
Re: Com' On PO - Dangerous Fuel Lines
If rubber is just as good as, and just as safe as, then GM would have used rubber the whole way on every vehicle. Times millions and millions of vehicles, it would have resulted in enormous cost savings and additional profit. But they didn't.

There is a very big difference in the quality of high pressure rubber hose and the crap they sell on the spools in advance auto zone....

Re: Com' On PO - Dangerous Fuel Lines
My question is what kind of Carb has the fuel inlet on the drivers side? Guess that I may be out of touch.
I would at the least get an OEM type metal fuel line from the pump to the carb. To each their own. Metal fuel line is best but rubber "FUEL" line has been used for years. |
Re: Com' On PO - Dangerous Fuel Lines
Nice looking engine compartment. It also looks like you did try and run the rubber lines neatly kudos for that.
As others here have already stated metal lines are the way it should be done. I don't think the premade lines will work in your case, I noticed the low mounted alternator along with the Holley carb. and the aftermarket fuel pump. Using the Holley will require a special fitting a special Banjo style fitting. a short rubber ( 2.0") run to your filter another short rubber (2.0") to the metal line to your fuel pump. Yes sanctioned events don't recommend flexible fuel line unless it is braided line. I used to run a Camaro that was run with 1/2 aluminum line. That was a Bit%% to work with it just wanted to kink. Good luck with it keep us posted and how about some more photos of it. |

Re: Com' On PO - Dangerous Fuel Lines
Put your fuel filter before your fuel pump, not after. It may be a pain to get under the truck to change it, but if you ever get trash in the gas, your fuel pump will thank you.

NHRA doesn't allow more than 6 inches total on the car, I believe. Plus rubber fails at a much higher rate than steel. It's probably even more than 100 to one. The more you have of it the more risk you take. What about road debris? Have we not all hear the "thunk" when something gets kicked up into the undercarriage? You'll dent a steel line, puncture a soft line. |

Re: Com' On PO - Dangerous Fuel Lines
WOW!! You guys know your stuff and thanks for the feedback. So when I decide to remove the rubber line can I put on a braided one instead of doing the metal? Also, is there a problem on where the fuel line connects to the carb, should it be on the passenger side?
