4180 SPOT

I was looking for the PN on my hot fuel diverter valve and while I was there decided to check the fuel filter. When I removed it I found the spring was installed like this.


When reinstalling it I found that the only way I could get it correct 100% of the time was to hold it against the filter element with a small screwdriver, then insert the assembly in to the carb.
I tried it a number of times and trying to hold it in place by hand failed more than 1/2 the time.

Now that I think about it, maybe this is a noob "discovery".

Hey Rovernut, looks like you're working on a 4180 Carb and you've got a couple threads going.

I just rebuilt mine and here's what I did with the inlet filter and connection to the hot fuel return.

I had some trouble getting the inlet fuel filter to seal leak free with the hard line running from the hot fuel return so I ran a piece of rubber fuel hose from the hot fuel return to the inlet filter. ! went with a Wix 33019 (NAPA 3019?) for the inlet filter as it's set up to receive a fuel hose. On the hot fuel return side I got a hydraulic line with the right flare fitting and cut it down to about 1 3/4 inch and secured the fuel hose to it with two hose clamps.

Sounds like a good workaround.
I've decided to go with a new Edelbrock carb. My 4180 is in bad shape and knowing my luck I'll get it apart and find it beyond redemption, or need other parts for it.
