Going to set my sho on fire!

[SuperHO]

walbro 155lph...more than enough volume, lasts forever and a day.

 

[zach44102]

but will a 155 be able to support 300-350 whp? 190's im sure can and i here of alot people running them on the stock regulators all the time and have no problems. can a 155 support that power?

 

[SHOtime2511]

Yes,a 155 will be fine.

 

[Mr Anonymous]

man people still cut holes in the floors of their cars and chop up fuel lines to avoid taking off two clamps and two bolts holding the fuel tank in.......? I can drop a tank on the ground without the car even jacked up in 12 minutes half inebriated.....

Yeah, I've never been able to figure out the cutting the hole deal.

We work on the nastiest, rustiest cars in the world yet I've never had an issue dropping a tank to do the pump. Yeah, the more gas in the tank the more of a pain it can be, but it still isn't exactly difficult.

Dropped a full tank once. Filled up, drove to school, and the pump died on the way home. And yeah, the 155 would be more than enough.

 

[SuperHO]

have either of ya'll tried dropping a rust belt tank in a driveway with hand tools and a floor jack? if so, ever done it without shearing a strap bolt?

FWIW,

I have a hole cut in the floor of my car (That has SFC's). It was done very well, with Hinges and a latch to open it if needed. I also added a rubber seal at the bottom and then put foil tape over the top of it, for extra protection. I think if it is done right it is a nice convenience to have.

Ive seen tanks so rusty that when the straps are pulled, it takes material off the tank with it, which means a top a new fuel pump, you now need a new tank as well.

Agree 100% . Done carefully it is a great mod . Makes testing/changing pumps a 2 min deal .

I cut an access door for my fuel pump. Works great for me. Hinged it and put a latch to secure it. Sealed it and put duct tape over where I cut. I did it to avoid having to drop the tank......I had heard of issues with rusty fasteners ect and wanted to avoid the headache.

At that point its a trashed gas tank anyways and its time for a new one. Wouldn't you rather find out about a gas leak in your garage/driveway rather than going down the road?

I think its a smart idea to install a gas pump door when the tank is dropped. That way you can do a good job.

As far as SFCs go its not a smart idea to modify a car in such a way that it won't be fully functional anymore.

Well its a price to pay for stiffening up our four door family sedan.

Just FYI, the stock 140 lph Walbro and the 155 lph Walbro are the same pump, with the same flow rate curves. Only difference is the plastic assembly on top. They were rated at different voltages.

 

[SuperHO]

stock fuel pump volume IIRC is 70lph, and none of my stockers ever had Walbro written on em anywhere...

 

[SHOtime2511]

The stocker on my 89 was a Walbro unit.
They are not rated at 140lph however.

if a car is that damn bad its time for the junkyard anyhow!

Oh really, what makes you think so??... all of the "stocker" pumps are Walbros.

The original factory SHO pump was a Walbro model 5526.

The current Walbro direct replacement pump is the model 526 (they dropped the leading five from the earlier PN for unknown reasons), rated 140 LPH.

 

[SuperHO]

huh...well i'll be dipped...

 

[zach44102]

if i remember correctly, 112 LPH fuel pumps in MTX, for some reason some ATX's got a standard 65 LPH pump.

Who cares what's in it, as long as it works.
