Im finally upgrading my fuel system to a higher capacity pump. Im going from the stock 045 to the 044 pump...and hopefully a bump in HP

From what i understood the 044 unit is a straight "bolt up replacement" for the stock 045 but as i always tend to find out, that is a relative term.

Ive added pics below to show what im looking at.

2 issues......

1) the stock pump uses a rubber hose and hose clamp for the intake side of the pump. The stock pump comes with a "barb" for the hose to slip over.
The 044 pump doesnt. It just has a female threaded port. Is there a part number or a theread barb out there that will make this work? I assume so.

2) on the ouput end you can see the fittings are differnt also. I would assume i should just be able to remove the 044 fittings and attatch the stock one to the new 044 pump.

Thanks!

Tony.............haven't done this project but would suggest:

1) use a 'compressed air' fitting to the intake side of the new pump that is threaded appropriately that shall also accept the rubber line and clamp.
2) remove the check valve fitting and check if the stock bolt shall fit and seal; if so done. If not you may have to get another 'banjo' bolt thats threaded for the new pump output.

Seal both with 'teflon' tape.

I thought that teflon and gasoline don't play well together...?

Hey Tony,

Are you still running lower-than 30# injectors? Do you get a drop in fuel pressure? What's leading you to believe you need more volume?

I found on that screws into the input AND outputof the pump from Earls. I will have to check it out when I get home. Its still in the boxes.

Depends what colour you use.

Ill try and tighten it a bit more tonight after trick-0-treat'n

Tony,

The 044 even looks "more flow" Need a pic showing the comparison...

What did you end up using to getter installed?

Tony

Hi Brian
I am using the 30lbs at this point. My last dyno of 448 rwhp was with the 24s. I dont have a record of a new fuel pump being put on my car so i decided to kill two birds with one stone...get a new one and a better flowing one. The new pump will just eliminate one more part of the equation when tuning the last 50 hp out of this thing. When i decide to Sharktune the 044 have the flow capablilty to deliver fuel with out haveing to skyrocket the fuel pressures to do it.

Hey Tony,

What is the 044 fuel pump out of? Where did you source it?
Is it noisier than stock?

Bump for the 044 FP source!

Tony

Thanks for the bump.
I didnt see Adams reply there.

as far as noise..i dont notice a difference at all? Actaully i think it is quieter than my old unit..it used to buzz now and then

FYI..i talked him to 222.00 shipped

Giovanni

Thanks for the info Tony. Why did you go with the Bosch 044 instead of the GSL392 that cost much less? I saw your other post on the archives about the 392.

Are we missing a post? I thought someone posted a picture of an elbow and a source of where to find the correct fitting

Tony

I think it was a post by Gretch somewhere that showed a 90' curved fitting on the end? I recall seeing it as well. Im sure Murph knows the part number also
I got the fitting i needed down at a hose/hydraulic shop. I needed mine "yesterday" so to speak as i wanted the car on the road...therefore..
FYI..metric parts are NOT cheap!!!!

i went with the Bosch unit as it does bolt right up into the stock area/brackets..the Walbro unit is much thinner and a bit longer. I didnt want the hassle of making it fit..
