have read other posts about fuel pump vapor lock issues but this problem seems a bit different
my jeep starts fine first thing every day. it has so far run just fine for any length of time as long as i dont shut if off.
tuesday i ran errands started fine in the morning ran about 15 minutes when i got back in it started fine ran it 60 seconds it stalled
took about an hour to find starter fluid came back and used the starter fluid twice on the second try it started up
the next day started cold just fine ran an errand about 15 minutes on the highway spent an hour in the store came out started up just fine but again huffed out in about 60 seconds.
starter fluid wouldnt start it. tried numerous times.
took off gas cap tried to start it using starter fluid no start
took off fuel line before fuel filter tried to start it no gas came out of the line
walked to gas station got gas put alot in carb didnt start. put alot more in carb and it started and ran just fine, sat about 4 hours then started just fine again.
started fine this morning when i did the fuel volume test.
so basically i seem to have an issue with getting gas either from the fuel tank to the pump or from the pump to the filter, NOT SURE WHICH when the vehicle has been runniing and it is shut off restarted and then driven about 60 seconds.
i checked my fuel volume when cold and i get at least 1 pint of fuel in about 10 seconds which is very good
fuel pressure tester is way too expensive to buy to test the pressure on the pump.
so while it may be vapor lock or a bad mechanical pump im leaning towards trying to fix all problems with one solution
electrical fuel pump
wondering if this will solve all issues, vapor lock, fuel lines heating up,a failing mechanical pump
etc etc etc??
seems to be the least expensive, easiest way to go?
so before doing this id like some feedback as to whether any of my assumptions are correct?
also need to know how to hook up the electrical wiring for the fuel pump?
can i just install new metal fuel lines with the new pump then connnect the new fuel lines right before the mechanical pump with gas type rubber hose? my fuel lines look rusted i dont see any leaks but figure i should replace, i do i have to try to remove the old lines? or can i just run new ones along side the old ones?
oh yes and how do i get the large nut type thing on top of the gas tank off?
ive done it in the past its taken forever and i end up ruining the piece to get it off.
appreciate any advice or help i know the post is long but its kind of a strange problem
started wednesday morning just fine. ran it on the highway about 15 minutes stopped came back out about an hour later started just fine ran another 60 seconds and died like it was out of gas. used starter fluid numerous times wouldnt run.
