Fuel lines - The 1947 - Present Chevrolet & GMC Truck Message Board Network

All this talk of trucks almost burning down has me wanting to replace my fuel lines, primarily from the pump to carb. right now i have a metal line running up from the pump to the top of the valve cover then a section of rubber line to a glass filter

then to my 1405. all connected with hose clamps and i don't feel good about my setup at all. i thought about the edelbrock setup but damn they are proud of those. what do you guys do?

Longhorn Man · 12-30-2005, 01:40 PM

Just inspect or replace all the rubber lines... look under the cab, there's some rubber down there and some right before the fuel pump too. The glass fuel filter is fine as long as you secure it to where it will not hit anything nor get smacked by anything. The latter should be no problem, but the former... the fuel line can flop enough to smack the valve cover, or even on the carb depending on the location of the filter.
The hard line should be a non-issue. You can inspect it, even remove it and clean it up and shoot some clear on it. However, hard line is cheap enough, you may want to just replace it if you remove it from the pump. If you are good with a bender, you can route it a little neater than stock. Just make sure it is secured well, and more than an inch away from heat sources. I like using addell clamps (cushion rubber lined metal clamps) and keeping it from touching the engine myself.
Take a good look at all the hard lines under the truck too, they are always ignored untill there is aproblem.

get a non glass filter, and some people like to use 2 hose clamps per connection.

Longhorn Man · 12-30-2005, 01:44 PM

2 clamps per connection can actually make the junction weaker.
You are only dealing with a few PSI here, you could seal it with Zip Ties and be ok...not that I'm recomending that, but it would work in a pinch with no leaks. I've done that one myself.

I went ahead and sprang for the edelbrock kit it worked out really well and I even installed a fuel pressure guage... I did run braided line fromn the end of the metal line kit to the filter and pump... Next on the list is new line all the way back..

bucket · 12-30-2005, 06:53 PM

what is the best way to transition from the hard line to rubber line? a compression fitting with a hose nipple?

where do you guys place the filter? on the vertical run above the pump or on the horizontal run above the valve cover. seems that maybe you would want as few connections as possible above the engine. less chance of failure above manifold.

bucket · 12-30-2005, 06:54 PM

the edelbrock stuff is cool looking and i bet its good quality but still...

anyone make anything similarn but less expensive? mr gasket maybe?

Longhorn Man · 12-30-2005, 07:41 PM

no need for the fitting, in all reality, that is another place to have a leak. just cut the hard line, and put the hose on there and clamp it. nothing special needed.
I like having my filter on top personally.

**53burb** · 12-31-2005, 02:29 PM

In the "chrome" section at Checkers/Kragen, they sell a chrome fuel line made by Spectre. It's only about 10 bucks. I believe you can get them on EBay as well.

Longhorn Man · 12-31-2005, 04:46 PM

If they are chromed on the inside, you should best avoid them. The chrome WILL flake off and clog ub the filter and/or carb.

*FormerMember* · 12-31-2005, 05:21 PM

I make mine out of aluminum line from Summit. You can buy the fittings as well and have a very nice and neat set up. My lines from the mechanical fuel pump to the carb are always hard line. I run braided from the fuel pump down the frame rail to the gas tank.

What is the edelbrock kit? Does anyone have a picture of it? What does it include?

Good suggestion, never thought of that when I installed it...

Here is a link to an Edelbrock fuel line on EBay...http://cgi.ebay.com/ebaymotors/Edelb...spagenameZWDVW....
they also have ones with a filter...http://cgi.ebay.com/ebaymotors/Edelb...spagenameZWDVW

I put a small bubble on the ends of the steel line where the rubber line slides over it. The bubble gives the hose and clamp more resistance to sliding off. Just like the all the fittings in your cooling system have.

**dennislbrooks** · 01-01-2006, 09:59 AM

I also clamped my top filter on the intake manifold to move with the engine vibes and prevent a lot of oscilation on the rubber connect lines. I pack a full fire extingusiher in each of my classic vehicles. Like TX Firefighter says do step one of a double flare also. I like the double clamps also.

Funny that you knew how I do them. I figured that out years ago, and I thought I had discovered plutonium or something, I was so proud.

Just use the flaring tool with the little insert for double flaring. Then, don't do the second step to the flaring process. It leaves a nice little bulge for the hose to grip onto.

now if we can just figure out how to do a metric o-ring pinch --Lewisville Hydraulics can do them
