Re: [DML] fuel pressure tester

["jtrealtywebspannet" <jtrealty@xxxx>]

The suction hose that I am referring to is the hose that connects the 
fuel pump to the baffle in the bottom of the fuel tank. It is very 
easy to kink when installing the fuel pump if it is turned as you 
reassemble. It also can get soft and mushy with age and under high 
flow it can collapse under vacuum. During testing this may occur.
Getting back to your hard hot start it typically is a bad fuel 
accumulater or a bad or missing check valve on the fuel pump. The test 
to check this by switching 2 plugs will not help you determine if it 
is either the accumulater of check valve as you need both parts 
operating corrrectly to hold up the rest pressure. To test for the 
check valve just clamp off the return line to the fuel tank and either 
watch the pressure or just try to restart hot. To check the 
acccumulater remove the return line and clamp off. Start the fuel pump 
and if fuel comes out the return of the accumulater the diaphgram is 
ruptured. If you do find yourself replacing the fuel filter or the 
accumulater BE CAREFUL WITH THE FUEL LINES. Kinking or bending them 
may require raising the body to replace them!
