Fuel Pump Confused
I think I have blown another fuel pump. I blew one 6 months ago, then 3 months ago and probably again. The first one which lasted 1.5 years was off ebay, second from the mechanic(Probably Advance Auto), and the third from Advance Auto.
Is there something I am missing? Please help!

fuel filter?
when a fuel filter becomes half clogged, the current flow required to pump the same amount of fuel doubles. high current flow= burned up pumps. just a thought, fuel pumps should last years not months

I'm not saying ..I don't shop at Advance..because I do..BUT especially on electrical parts you're better off with OEM/ GM parts. There's a reason many aftermarket parts are...hmmm....cheaper JMO

I thought about fuel filter before also. It is probably the original one from 87. I tried to find it but I couldn't find it. Does anyone have an 87 that can tell me where to look?

On my 87 its located passenger side on the inside of frame just before wheel opening. Just follow your fuel lines from the motor towards back of car. If you change it try to run your fuel level down ¼ tank or lower, relive your fuel pressure, either at Schrader valve, or pulling fuse while running, open the fuel cap on tank, and be careful there will be gas dripping it's a easy but messy job.

Here we go again. I store my vette for the last 3 months and now I have it out. I filled it up with gas and the hesitation is back. That has been a good sign the fuel pump is dying again. Anyone have a link to a good durable fuel pump? It is an easy job but it gets old after a while..

Walbro makes good pumps.

Something else must be wrong though. I'd change that fuel filter for sure. Also look at the wiring really good. It might not be getting the correct voltage because of some corrosion. Good luck! Hope this next time is the last for a while.

The problem sounds like a old/never changed fuel filter. Take a look at
Racetronix fuel pumps. The kit they sell is complete.....not just the pump but "EVERYTHING", (gaskets, 9 bolts, silicone, fuel hose, clamps, the sock, the electronics and more).

I love my Racetronics kit. I've had it over a year now with no issues.

I know where the fuel pump is. What I meant to say is that I can not find my fuel filter. I have looked on the passenger side 4 times now and I just don't see it. I can find the fuel lines running down the side of the car and then it goes up and disappears on me. Do I have to jack up the car to find it? By the descriptions I assumed it could be worked on without jacking up the car.

Even getting a visual on it it's still not easy to loosen the nuts and get out. Working room is very tight to say the least. I could not get mine out till I had to replace the starter and then it was do-able. The other common way is to un-bolt the lower nut on the filter and then separate the fuel line at the top of the engine and take it out (fuel line and filter) together.
I was lucky I guess to have a bad starter shortly after I bought the car which made it possible for me to do the filter easier. Thing is, I’m about due for a filter replacement myself.

They all forgot to tell you it is behind the front pass wheel
Only accessible from underneath and has a metal heat shield hiding it.Follow the fuel lines that run along the rocker panel forward to where the firewall angles up from the floor pan and you can't miss it

The pulsator is in the tank with the fuel pump. It is the sort of oval metal cannister the fuel lines push into with the red silicone rubber bladder inside.
Usually, after about 20 years, the red silicone relaxes a bit, and your fuel pressure just squirts around inside the tank.
Get about 5 inches of FUEL INJECTION HOSE not fuel hose. Fuel injection hose is good for 70 pounds of fuel pressure, and regular fuel hose is good for about 25 pounds. Your pump puts out 45 PSI in running pressure, but pulses up to 60 in some instances when you go from high fuel demand to idle in a hurry.
and yea, jack up that beast, it's right behind the right front tire on the frame rail out of sigt, but placed correctly to have gas run down your arm into your pit and make you run to a faucet real quick.
