1972 Fuel Line

[Martin Z.]

I'm confused.....Is it true that there is no rubber fuel line material on the pressure side of the fuel pump to the carb on all 72's? If so, where can I find a steel line from the pump to the carb for my 72 LT-1? Thanks in advance.

NO 1970 to 1972 Corvette had rubber on the pressure side of the fuel line. Lots of other newer years also. 1968 and 1969 with that fuel filter at the passenger side head had some rubber line, but AFAIK it is on the low pressure, return side -- but I will defer to those more familiar with that installation to be sure.

Yes, 68-69 with Q-Jet used a rubber connection ONLY on the 1/4" fuel return line. I don't know of any 68-82 application that used rubber anywhere on the pressure side of the pump. In fact, as I recall, the use of a rubber line on the pressure side of any C1 or C2 Corvette was limited to a few earlier C-2 applications.

Thanks Joe for the confirmation. I was pretty sure that was the case because rubber on the pressure side of a fuel pump is a HUGE safety issue. I cringe when I go to show & shine type events and see some of the fuel line "modifications." I am sure a number of good Corvettes (this is not exclusive to Corvettes -- I have seen a lot of squidgie fuel lines on Chevelles too) and other fine Chevrolet products have gone up in flames because of this oversight.

No Corvette after 1965 had any rubber on the pressure side of the fuel pump; all had steel lines and SAE inverted flare fittings.

In 1968 a friend of mine factory-ordered and purchased a new 1968 Chevelle SS 396 with L-78 engine and M-22. He took delivery of his car fairly early in the model year and his car was built right here at the GM plant in Fremont. Of course, the carburetor used for this application was a dual feed Holley. His car was delivered with rubber fuel line from the "Y" block to each of the fuel bowls.

A few months later I ordered a new 1968 Chevelle SS396 with L-78 engine and M-22. Mine was delivered to me in May, 1968. It was also built right here in Fremont (with my roommate at the time, a foreman at the GM plant, following it down the line). My car had steel fuel lines from the "Y" block to the fuel bowls.

When my friend saw this, he returned his car to Central Chevrolet (where we had both purchased our cars) and told them to change the fuel line to steel. So, they did. Of course, very few pre-formed fuel lines were ever available from GM, so they made up the lines from stock. My friend assumed they would do this replacement under warranty. He should have confirmed that first since, as it turned out, he was mistaken; they charged him for the work. They said the car was built with a factory-approved fuel system and just because my car had steel fuel lines did not mean that Chevrolet owed it to him to replace his so they were like mine.

He traded in that car in the May, 1970 and replaced it with a factory-ordered Z-28 Camaro. He still has that one. It's the one that's got 186 original miles on it today; he only drove it the day it was delivered to him and never again.

I'll probably be going to a local car show with that guy on Saturday. I'll remind him about the Chevelle fuel line. I'm sure he has not forgotten it, though. It "stuck in his craw".

Re: 1972 Fuel Line

I am surprised CHevroelt would do that (use the rubber on the pressure side.
