Engine leaking by the gas pump
« on: January 12, 2014, 12:48:52 pm »
Yester day I install a 700r4 in my truck and it work fine for couple of hours then it gave out and today I checked it out and I got it to run but my engine started to leak by the gas pump. So I was wondering of the transmission had something to do with it because that motor is just rebuilt from October 2013 and it wasn't leaking anything before I put this transmission on. if anyone know what can be wrong with it and it's also started ticking
I have a 1985 Scottsdale with a 350.

What type of fluid is leaking: gas, oil, coolant, ATF?  Are you saying you have a fuel leak from the fuel pump?  Is the fuel pump new?  Is the transmission still shifting correctly?

The leak is coincidental.  Unexpected things happen.  Try to determine from exactly where the oil is leaking, keeping in mind that oil runs downward and back away from the fan.  Carefully inspect the 1/8" vent holes in the upper half of the fuel pump body; inspect the fuel pump and adapter plate mounting gaskets; and make sure oil isn't leaking from an open bolt hole or loose bolt in the vicinity of the fuel pump.  In addition, valve cover leaks are a regular nuisance.

Use a 3' length of 1-1/4" rubber hose or a mechanic's stethoscope to try and pinpoint the "ticking noise."  Determine whether it's coming from the fuel pump, one of the valve covers, an exhaust manifold, or __________.

Recheck the transmission fluid level with the engine warmed up and idling and with the transmission in Park.  Did you connect and adjust the TV cable?

Yeah I checked everything you think it's the gasket for the fuel pump that's leaking it out

You didn't connect the transmission fluid lines to an engine oil cooler by mistake, did you?

clean the fuel pump and take the fan off but put the nuts back on. run the truck a little see if/where its dripping from.
