Diesel leaking

March 31, 2020, 04:26:36 pm

My newly acquired 1998 320 36' Foretravel has developed a diesel leak coming out of the aquahot exhaust hole in the middle of the fiberglass under belly. I took the cover off the aquahot and it looks ok. Had it serviced at MOT a month ago. The leak is a drip every 10 seconds. Fuel tanks look ok from what I can see. I used the aqua hot yesterday and it works fine.Shut off circut breaker thinking it may be a fuel pump to the AQ?. no change.
Any thoughts ?

Probably fuel lines or fuel filter if yours is in the cabinet. Next up would be the fuel pump if it only leaks when running.

When I changed my filter out I discovered the filter lead tube had cracked. I had some diesel on the floor, but not enough to leak like you explained. Filter is an easy fix.

Well I found the leak , it was a cracked fuel hose to the AQ motor from the filter. Replaced and not leaking or explosions.
Not something I want do do again.Thanks for all your in put.

Be sure to clean up ALL the spilled diesel.  If it gets down into the basement "sandwich", it will dissolve the insulation AND give your coach that diesel smell forever.

Other than cutting it out, not aware of one.

The sandwich I am talking about is below the floor of the basement.

Thin layer of fiberglass forming the floor of the basement.

Box beams with foam insulation where there is no beam.

Thin layer of fiberglass forming the bottom of the coach.

You can not access the sandwich without cutting.
