Hi !

Can anybody help me with undercar fuel line size....there are 3 lines, 2 of size A and 1 of size B. I want to know the size to order from the part store.

See picture attached. I am talking 13, 14 and 15. My thoughts are 2* 3/16 and one 1/4.

Second question, I notice that only the line of the filter (out probably) has fittings ? What is the fitting size ? The rest are holding to a rubber only...is that right ?

Thanks

3/16 and 1/4 ?

 

they are going to be metric. either 8mm and 10mm or 6mm and 8mm. 13 is your feed, probably 10mm, 14 is your vent line, 15 should be 8mm rubber hose to the regulator, and 16 is actually the return hard line. hth.

 

Thanks.

When replacing brake line, you use 3/16 tubing. Part store don't sell metric replacement hoses uncutted...

 

the thread pitch on the fittings will be different. i suggest you try to find a different parts store.

 

Most parts stores don't sell metric hose. If you know of one (a major player, not some unique mom and pop or specialty store), please let me know!

 

Still searching for answers from someone who has done it !

 

Pressurized one is 3/8

Vent and return are 5/16.

For future references.

 

buy a length of brake line, reuse your old fittings if you can find new metric ones and flare the ends.

 

Yes...I will definatly do that. Thanks a lot for sharing ! I got used to flaring for the brake lines, and am ready to attack the fuel ones

Only the big one will have to be flared though (the feed), as the return and vent don't have fittings, just oversized end connecting to ruber hoses.
