Plastic Fuel Line 1990

Recommended Posts

What size is the plastic fuel  line from the filter to the engine on a 1990 Reatta ? Mine somehow became nicked/leaking.

Mine isn't at home but the majority is steel with a flexible hose or similar down above the filter?

OK I must be imagining the black plastic line under the driver's door that is spraying gasoline when the engine is running.

Could that be the return line from the regulator to the tank?

Could be anything that has fuel under pressure. Just know I must fix about a 1/4" blowout. Guess I'll just have to "get out and get under".

Yes it's plastic (nylon?) and it can be spliced. Done it many times were the squirrels chew on it. Not sure of the size; 5/16 maybe.

Spices are barbed nipples that you heat srink on.

It's plastic the whole way on mine.

Now I'm not so sure. I went to look at the '90, and the lines in the engine bay are steel.

Too damn cold here to crawl under to check.

I DO remember getting a replacement plastic line from Jim years ago.

Page 6C-4 in the FSM states the fuel and return are both 5/16" id., plastic. I found this in the PDF's that were so kindly posted by AZvet

Just to clear up some confusion....

 

On 1990 and 1991 Reattas, the lines are stainless steel starting at the fuel rail and going to about halfway down the incline where they go towards the back of the car. 

 

On a coupe, this is where the fuel filter is located. 

 

Padgett is presumably working on his 1990 convertible. On the convertibles, they transition from stainless to plastic at the same point. HOWEVER, if you've owned a convertible, you know that the fuel filter is located just in front of the drivers rear wheel. 

 

'88 and '89 Reattas are a whole different beast when it comes to fuel lines. 

 

You can buy kits to splice GM plastic fuel lines together. They're not cheap, but they work well.

Thanks for the information. Never owning a convertible I wouldn't have any idea of that.

Thank you Marck.   Padgett, on my daughter's (beater) 1990 Claret COUPE after purchase a leak developed just beyond the fuel filter going to the engine area.  I looked it over and decided - for us - to take the piece out which was leaking and replace with a rubber gas line, highest quality, from O Reillys.   This worked. Hose clamped it snug to the existing lines to and from and never had an issue after that even though the plastic line was not flared.

Well I bought a Dorman 800-012 barbed splice from Amazon, cut out the nicked section and shoved the two pieces together Really Hard (over at least three barbs on either side) seems to be working fine.

 

BTW on my 90 'vert there under the mid-back door area, there are two 5/16 plastic fuel lines
