Default Walbro 255l/hr fuel pump install pics

First of all, this is NOT a one-person job. I suggest 2 to remove, 3 to re-install the tank. I had this sucker so empty, it barely made it a mile to the gas station when we were done, and it was still a BITCH.

Tank removed from the car:

Debris on the rim of the tank. This was removed by putting duct tape around the INSIDE of the lip of the tank, sticky side up, then gently brushing the debris onto the tape for removal. You don't want to use vacuum here. One little spark can ruin your whole day:

The baffle shouldn't cause any problems, as it cracked on the upper portion. The 93 still has a more accurate and stable sending unit than the 95 anyway. On of my strap bolt anchors broke during install, and I have it rednecked now. I'll have to order the retainer nut and a new bolt for a 15min fix later.

Man up, bud. I did it three times all by myself with enough fuel to get me to town, 20 miles and still have enough to run errands first.

I had the same shaped baffle pieces come out of my tank.

You can get the anchor from the help section at Autozone.

EDIT: I never even dropped the exhuast...

I went with OEM anchors and bolts. Just ordered from the dealer, they'll be here tomorrow morning.

I didn't 'drop' the exhaust, but I did undo the rear hangers and pull it to the side.

Bill..on that three person install is that two for holding the tank and one to connect wiring?

I think that'* what we did on Frank..but he was also pretty high up on jackstands at that point. And I think Toasty took a gas tank hit to the forehead too.

3 to install would make it MUCH easier. Not for the wiring or fuel lines, but to jimmy it up into position and hold it for the straps.

Bill how would you rank a bonneville tank dropping to other vehicles you have done?

I just got done doing this on my car. . . .I feel your pain Willwren! I did it by myself and couldn't drop the exhaust in the back because it was so rusty.

I curious to see what you FP will be now. I was going to do the same pump as you but then Zoom talked me out of it when he said that he isn't sure if the bonne FP wiring is as bad as the GP'* but if it is there would be chance that it could flow worse if voltage isn't high enough. So I just went with a GM one figuring I'd never get to the point where my pump won't flow enough let alone my injectors.

Blazin, I'm at 48psi with the key on, engine off. I jump to 51 idling if I disconnect my vac line. No problem with the wiring current carrying capacity for the Bonneville.
