petrol tank feed pipe nipple

[jcrcleeman]

Can anyone confirm that the nipple has to be soldered onto the outlet pipe?

I've found quite a few general threads but nothing specific to the nipple fastening.

I've also seen mention of the pipe having a "swaged " single flare end, is this an alternative method?

Is it a simple diy soldering job? ( as I don't really want to have to buy the full pipe etc if it's simple to do it.)

I'm pretty sure it's not a compression fit but thought I had best check it out.

The nipple is soldered onto the pipe as per the picture. If not soldered and a poor job is carried out petrol may leak from the nipple which is dangerous and air may be drawn into the pipe resulting in poor delivery of the fuel.

Point taken Phil.
New pipe ordered!

No significant amount of fuel could leak out because it's on the suction side, but the air leak would make the pump ineffective. If you can solder, it will be fine. If you are using a steel pipe, a good flux is needed. Pre-tinning is a good way to inspect it before the fitting goes on.

On Tuesday I had a new pump and pipe fitted the tank was just under half full was below where the pipe goes into the tank. When I got home I put a couple of gallons of petrol in and it started dripping out of where the pipe went in to the tank so the garage that fitted it drained some off and refitted the pipe and put the petrol back in and is not dripping now. The mechanic said they can be a bit of a fiddle to get them to seal and I know people that have fitted petrol pipes and usually takes two times before they seal correctly.
