I'm wondering if you guys have any suggestions for a fuel pump for when I put the 89 engine in my 85 GS.

I was looking at a GSL-SE pump but thats 350 from mazdatrix. Completely rediculius.

Which aftermarket pumps would you reccomend?

 

why not take the pump from the 89?

 

aftermarket ... Bosch

 

just about everybody i asked said that the 89 one wouldnt work, including the person i bought my 89 boltons from.

even if it would work, i dont have the opertunity to get it now. i just dont know what fuel pumps will work with the 89 engine and fit my car at the same time.

 

lol, ya replied while I was typing. Any model in particular you would reccomend?

 

no ... not sure what model, but aren't you going to have to do fab work on you tank anyway?

 

you can graft a intank pump onto a first gen fuel pick up, for a n/a motor i would recommend a walbro 255 pump.

 

use a msd external pump..... $180.00 from summit or jegs... in tank pumps wont work on pre 86 cars or get a SE fump from a wrecking yard... they usally sell for $60.00!!

 

I am??? This is the first I've heard of it....

 

well, yes, if you decided to go with an in-tank pump. even if you decided to go with an external pump, won't you be beefing up the lines in and out of the tank? just curious ...

 

it will be an external pump and I will upgrade the lines.... i just thought you were talking about fab work on the tank itself...lol

 

If you plan on running an external pump you're gonna have to either fabricate a sump for the fuel tank or install a surge tank.

 

no since i'm a big n00b here... why would I have to make a sump? I was just under the impression that I put better lines on the tank and lead them to where the current fuel pump is.

Now I can probably allready guess that I'm horribly wrong so could some one tell me why this sump is needed?
