I am doing the kits as well, it makes sense to replace them all why you have it taken apart.

Here is a better view of my passenger side now that I have the battery tray out. Looks like ample room to work.

Wasn't there a recall a year or so ago for these leaking high pressure fuel pump gaskets (not the current one for the low pressure pump)?

It was for the fuel pressure sensor gasket where fuel leaking past it was a possibility. It was a safety recall, often referred to as Safety Recall ELF (E2F).

Yes, VERY different locations and procedures to change out the gaskets for each.

For those who have done this, I’m reading the first post write up. Leaving the vehicle overnight will reduce pressure in the fuel pump? Is that right? So if I let the car sit overnight then before working on the gasket replacement, I remove the negative terminal on the battery, then there won’t be anymore pressure?

what happens if I don’t wait overnight and there’s pressure? I definitely don’t want a CEL as I’m terrified of those lol.

I just removed my passenger side pump this morning Allusuc and when I disconnected the fuel lines there was virtually no residual pressure. I disconnected and removed the battery two days ago and the car has been sitting since then so plenty of time for pressure to drop. There are other procedures to reduce pressure more quickly if you need to, but if you plan on just waiting it out I think over night would be long enough. Just remove the first hose slowly to be sure you are still not pressurized. I do not believe you will get a CEL if you still have pressure, but you do risk fuel spraying out and making a mess so you may want to wear safety glasses.

thanks! I will park my car in the driveway the night before and unplug the negative terminal. So 12-16 hours if it sitting unplugged should be good. I’m assuming that you did not losing your gas cap? I’ve heard others doing that the night before too.

also, question: since the battery will be disconnected for 12-16 hours, when I put the negative terminal back onto the battery after I’m done with the gasket repair, will i have to reprogram saved radio stations and the time/clock ?

When I did both gaskets I disconnected the battery overnight and loosened the gas cap. There was no pressure in the lines.

Correct, I did not loosen the gas cap, but it definitely could not hurt to do that. I do believe it will be necessary to reprogram radio stations and clock once the battery goes back in.

I have now completed both the passenger and driver side fuel pump gaskets and everything went according to plan. I did this work concurrent with replacing spark plugs and valve cover gaskets. Here are a few pics of the end result.

Passenger side before

Passenger side after

Driver side after

How did you do the driver side? I can’t get the black box out the way to remove the 2 bolts holding the fuel pump gasket in!


this black box here. Ton of wires underneath
