5.3 fuel line

"you can also use aliminum tube and an fittings. its easy to bend and cheap.
3/8 fuel line- http://www.jegs.com/i/JEGS/555/15100/10002/-1
compression fittings- http://www.jegs.com/i/Earl%26%23039%...65106/10002/-1
pay no attention to that 50 psi max bull stuff"

It shows use for only 25PSI, can i use this safely? what have you used?

I used my stock fuel line(hard line on frame) and used the hard tube adapters to -6AN to go to motor and fuel tank.

I just plumbed mine using dorman hard plastic line and fittings, like new style vehicles. this is the first time I have used it, but seems to work pretty good.

I used factory gm plastic quick disconnects and high pressure rubber fuel line (goodyear).

here's a pic of the connection at the rails....

I used the Jeg's 3/8" aluminum hardline for my LT1 and I havent had any problems so far. I used the AN adapters to the stock quick disconnects on the engine. I run at least 40 psi at idle and Im sure 10 psi or more over that at WOT the Walboro pump will do up to 100 psi if unregulated so I am confident so far. Hope this helps....

I used aluminum fuel lines, and -6 AN fittings. I have some braided stainless hose also to allow for engine movement as well as from the tank to the fuel filter/regulator. I used some QD fittings as well.

Where Did you get the factory quick disconnects?

[72truckman]

... And is that Fuel injection hose different from just regular fuel line?

[Sicmaro]

I got the quick connects from the crashed vette. they are the fittings for the fuel filter. the hose is fuel injection hose, has a plastic liner instead. thin blue plastic surrounded by the black rubber. I used high pressure clamps also.

Im computer challenged tonigh and cant find anything..... where did you find the high pressure hose clips

Also, could i have a pic of your corvette regulator mounted to the frame?

I bought the fuel injection hose clamps at Advance Auto Parts when I did mine, they are specific for this purpose and they have all the popular sizes.

Most of my clips our the clamp down style. I got those from my old shop i worked at. They do make screw down style high pressure clamps. should be able to find them at most auto parts stores.

I didn't use the vette regulator. I used a truck fuel rail that was regulated and had a built in return line........
