I have fuel squirting out if the top gasket on my fuel pump, case 4-390. Can I just remove the top cover and replace the gasket. From what I hear there is much more to it then that.
Once u get the top cover loose, you’ll see a main gov spring and an idle spring..
It’s VERY IMPORTANT that you pay attention to what holes the spring is in..
I wouldn’t take it apart until u get the replacement parts/gaskets..
U can go to eBay/Amazon and get a mini kit to reseal the top cover only.. it costs between 9-12.00 w/free shipping..
Just Google CAV DPA top cover leak..
One more thing to watch for is.. when putting the cover back on, MAKE SURE u engage the shut off bar w the nub on the shut off shaft.
It’s a diy job..
BUT.. the cover shouldn’t spray out fuel for no reason.!!
REPLACE THE FUEL FILTER..
Yes I believe soIs it a CAV pump
