Does anyone know the thread and size of the banjo fittings bolts for the gas tank. I will Like to plug those up and remove the factory lines since I ran new fuel lines. Thanks

 

I am not 100% sure but are they not M12x1.25 ?

On the MKIV , I believe from the hanger and into the oem filter it is M14x1.25 and out of the filter it is M12x1.25 . If I remember right , they are same as that filter out banjo bolt.

 

no need to replace bolt , just cut line undercar , use a fuel hose and clamp a bolt on it as from the banjo bolt upwards into tank is a long metal tube that feeds the system .. i use the feed and return banjo connections as a way of returning fuel back to tank

 

i really want to find a plug and install in where the banjo bolts use to go with a o-ring. I just feel like thats the best way to do it. I will probably removed the banjo bolts tomorrow and see what I can come up with.

 

They're prob 14m x 1.25 or 12m x 1.25 like gerrb said. Pull one, take it to the bolt place and get a short stainless bolt and new crush washer. Use a factory crush washer, do not use an o-ring. I usually drill out the banjo portion bung on supras and replace with a bulkhead fitting.

Anyone that tells you to plug a line with a hose, bolt, and a clamp, especially dealing with fuel, is ghetto. You're going about this the right way. Good job.

 

i guess you dont know how the sc fuel lines run in relation to the bottom of tank .. theres a small hole next to the banjo bolt that will leak fuel if you dont weld it up .. just replacing the bolt is not the answer

and no its not ghetto as theres zero pressure .. all you need to do is cap the metal line inside the tank as it runs upwards inside tank then down the hanger to pump .. just cap it right there and be done with it

btw , i run 1000 hp fuel systems , so i might have a small idea about our fuel supply systems , maybe

 

What do you do about the return? I didn't know there a hole next to the banjo bolt as I haven't taken it off yet.

 

Hey lexforlife. That's nice your fuel system is capable of 1000whp. But you're advising someone to cut a line and use a piece of rubber hose and a ****ing bolt in the hose to cap it off. THAT IS GHETTO. This dude is trying to make his car proper and clean. Don't derail him. In fact, I have never installed a big fuel system in an sc. So tonight I'm going to go look at my gfs car because I can't force myself to believe anything from someone who would suggest something along the lines of putting a bolt in a hose with a clamp.

 

well its not like you are plugging a line that is still being fed by the pump, its a leftover line that is essentially like a vent now if I understand right. fittings would be better but look out for the little hole that was mentioned, most likely there is a better way to block it but it doesn't seem that bad really if there is no pressure on the line.

 

Both ways would work i guess it just depends on how the OP wants to tackle this.
