Fuel Pump

[MustangSHO4-8]

Hey, so did some tests and am finding that my fuel pump is lacking proper output, I have heard of some people uprading to a bigger pump or some nonsesnse like that. If anyone can elaborate for me that would be awesome.

what did your data show?

Replacing your fuel pump with a walbro 155 will do the trick if your pump is bad

If you have trouble getting a Walbro (I was in a hurry and just went to Autozone) you can use the pump for a Mustang. I don't remember the exact rating, but it worked out very nice.

Remember he has a GenIII, I don't know if it makes a difference with the pump or not.

my fuel volume was like 5oz. in 15 sec and should be more around 8-16oz in 15 sec
and my running pressure was at 32 psi and should be between 35-45psi. Im pretty sure my pump has been on the down slope for a while now, ive been having to double key it to start the engine so the check ball valve inside is releasing fuel pressure back into the tank. I know Napa wants $165 for the pump checker is like $195for pump and like $380 for the whole drop in assembly.

Just to make sure, you replaced the filter, no?

Just checking...

yeah i replaced filter like 2 or 3 months ago with a napa gold, im gonna replace it first cause there is the possibilty of it being clogged, and its cheap enough.

oh yeah and the old one i replaced didnt have the greatest of fluid coming out of it, kinda rusty colored!!! So im thinking like maybe a new tank and pump and filter would be a really good idea if i can afford it.

I've heard of people with old-school muscle cars that get their fuel tanks cleaned out, it has to be cheaper than buying a new one.

On my 89 I installed a Mustang 5.0 155lph pump. It fit perfect, I only had to shorten a small piece of rubber hose inside the tank. $85 from Summit.

I think my pump is trying to tell me that it is on the way out too. The car still drives fine but it is a bit noisy now.

A Walboro for a mustang will work with a little modification. Thats what Carter has in his.

yeah, in all data it charges like .7 hours to clean fuel tank which is that there supposed to steam pressure wash it out i believe??? ya i would rather clean it out then have to buy a new one which will run me like $465. Ill look into the other fuel pumbs but i am thinking ill just stick with oem since im not going to mod the car at all, at least for right now. Gotta save money to finish the stang first so i can bring it down here!!!
