Fueling & Injection - 98 walbro pump install

Install was easy.No bucket to mess with.Any questions let me
know.

Huh, looks a lot different than the years after it. Does the stock pump unit come out fairly easy? After it's out what do you do... Put new pump in and splice the wires together?

Because the stock tank has no baffles I choose to keep my bucket for improved fuel pickup when the fuel level is below 1/4 tank.

I heard the 98's were not in a bucket...? Heck, all I know is i'm no expert. lol

I'm thinking about replacing my unit with a Walbro. Where did you pick yours up from?

the metal tanks have a built in slosh panel. the 99+ cars got a plastic tank and put the pump in a 'bucket' to keep fuel around it.

pictured is a metal tank install.

so what comes witht the racetronix kit that makes this whole process easier

Whats the part number on that 98 walbro pump? 340?

Thanks man

i got a mechanic working on my car i hae no time to do it my self my question is i got a 98 camaro and it does not have a bucket and the wlabro 255 will not fit in the stock container the bottom tube does not fit in the stock container so my question is if i were to mod it the way i see in the pic above wouldnt the gas act as a conductor to the positive and negative wire and would it not cause it to explode thank you

I just noticed now you used Butt Connectors to make your connections for the Ground and Power to the pump. YOu might want to change those, I've seen butt connectors loosen from vibration and loose conductivity. Heard a bad story of a local shop using butt connectors on injector wires and cylinders running lean with bad consequences.

Great thread. I will be replacing mine soon. Thanks

mr freeze, no worry about any explosions, i know it is counter-intuitive, but no worries

butt connectors have the potential to work ok. acutally i have 4 of them in my gas tank of my car.

Butt connectors on any component that delivers fuel is asking for problems. I can't see how you soldered the pump connections on that pump install that is a sticky and not your own. But hey, to each there own.

I picked up my Harness install kit today with the pump...I'll post up some pics later on tonight.

Was much wiring involved?
I will be replacing my pump soon.

$100 Walbro
$232 Racetronix

The Install kit comes with a plug and play harness that plugs in the walbro pump and the other end has a harness to plug into the factor harness. I'm taking pictures right now in the garage. I'll get them up shortly.

*waiting* :)

Just finished making my wiring harness tonight.

Here's the pics:

Pictures of the Walbro power and ground harness I took apart with a pick. Thicker gauge wire pictured on the left and the stock wiring on the right.

The new thicker gauge wires on the lead I pulled out of the Walbro pump harness. I soldered them as well as crimped them and heat shrunk the ends so there is no chance of them getting loose and coming apart.

Once the connections were done I put the leads back in the walbro supplied harness.

Then I took the leads out of the other factory harness with a pick and took out the factory small gauge wire. The new thicker gauge wire slid in perfectly and I Crimped Soldered and heat shrunk it as well again.

Then I put the leads back in the factory harness making sure they snapped back in place. And here's the finished Thicker gauge harness...

This was a nice easy job to sit at the work bench and throw together. I'm going to be replacing the rest of the factory wiring outside the pump this week upgrading it as well. Now I am finally going to drop the pump in the tank!

Just finished dropping the pump in and fired it up!

I extended the bottom of the pick up on the pump and test fit it a few times to make sure it wasn't pressed up against the plastic slosh bucket in the tank. The fuel feed line clears the top of the tank and still flexes without binding or pinching.

I'm definately going to do it this way.10mins :Dof cutting vs 4hrs of work.:mad:

was the wire you used Teflon jacketed? the Teflon jacketed wire is much more resistant to fuel than standard pvc jacketed wire. Other wise that install looks good man, rock n roll!

There isn't a worry about not having the fpr filtered and it doesn't have to go down to the level of the sock?

There isn't a worry about not having the fpr filtered and it doesn't have to go down to the level of the sock?nope just tie it up to a side The only reason the stock setups have the return redirected back to the sock is 'cos it's already filtered though the sock and the filter and so they dump it right back at the pump to keep the sock clean in the long run.

is a straight pain in the ass unless you notch like SPAZ1 said..i know i am going to after i drop the tank again..i am not cutting on top of my fuel tank if its leakin..ya know?

I used the kit from racetronix... I still had to drop the tank down a bit to get the lines off and it was really hard to get the pump unit back into the tank through the hole. Now my fuel gauge doesn't go to full anymore. I am going to pull it apart again when I put it away for winter.

It was easy to get the pump out. I just took the float off and the pump slid right out.

this should be a sticky since the 98 people are left in the dark when it comes to fuel pumps
and the 99+ guys got their own sticky and discussion
helped me a hell of a lot!

Mines an 01 so it doesnt have the baffles. I bought the racetronix pump only for $150 (I didnt see the need for the harness) and its been great especially since it fits in without modifying the bucket its been good for about 6 months now.

hey what sock fits the 255 pump? the 98 sock is way to small.

Why are 98's left in the dark? Racetronix makes a fuel pump kit specifically for 98's. It's a straight forward install. The only thing that really sucks is the metal tank itself is not as easy to move around compared to the plastic tank when you drop it.

I just pulled the piece out of the sock and it fit right on.

I had a really hard time getting the pump back in on my 98 it is mounted on a springloaded leaver and It didn't want to go down the weird shape just at a weird angle.
