New to me 802a puking fuel :(

Hey guys! Long time listener first time caller. Thank you for all the info guys! Y’all helped me out with my first 803a that got us through these 2 hurricanes in Florida. Our house only did 30% load on the 803a so I recently purchased an 802a as I thought it’d be better matched for our house.

Seller said it was a perfect runner. Dummy me bought it sight unseen and paid an arm and leg to have it delivered. Unit fired right up and ran for 15min while I checked vitals. I discovered it’s puking lots of fuel. Runs great, I was hoping it was the return lines like I had to do on my 803 but unfortunately it looks like it’s coming from one of the pumps. Can someone point me in the right direction? I’ll uploaded a video.

I'm excited to hear the experts weigh in on this one. My one suggestion would be to pull the clear fuel out of the tank and put some red dyed Diesel in, that might make it easier to find the source back in there...maybe it helps, dunno. Good luck!

Are you sure it's coming from the metering pump itself and not the rubber line feeding the pump?
It’s dark now so I’ll double check in the morning. But first look I don’t think so. I put my hand on the line and it wasn’t wet at all. In the video you can see the bubbles at the base of the pump. The other pump doesn’t have bubbles like that.

Check your oil too, just to see if the crankcase is full of fuel. There's nothing at the level of the block on the metering pumps that can leak fuel. if the pumps are dry up above the fuel inlet line it has to be coming from the inlet tubes or hoses, there's nothing below that which would leak on the outside of the engine.
Also make sure the pumps are tightened down all the way. Loose pumps won't leak fuel, but if they are loose at all and fuel from up above gets under the mounting surface, the vibration makes it appear the fuel is coming from under there, but it's really not.

im going to replace the rubber inlet lines tomorrow just to be sure. Any idea what size they are? My fear is the pump body is cracked.

Look and see if there are little band clamps on the end of the rubber lines, at the metering pump. Based on what I see, my first guess is either dry rotted lines at the very end, or missing clamps. Much more likely to be a line issue than a pump issue.

My 803 has clamps. 802 has no clamps on the feed. Are these 1/4” hoses?

If the stock lister clamps are missing, you can use small hose clamps. To tighten properly, you may need to loosen the cast iron hold down on each pump, after replacing the line sections, so the worm gear body doesn't interfere.

Identical design on 802 and 803... Something should be there. I think they are 1/4". I'd need to search the forums for part numbers I have previously used. I exclusively use Gates Safety Stripe line for both pump and return lines. Available on the roll at your local O Reilly's.

thank you for your expertise! This forum is a wealth of knowledge. Going to try clamps and hoses in the AM!!
