Fitech Fuel Pump Bosh 69100

On a recommendation I decided to try out the Bosh 69100 fuel pump to replace my noisy Aeroflow that came with the installation kit. I go to plumb it in and noticed that the fittings are not for 3/8 but rather 5/16. I am hoping someone who is currently using this pump for Fitech could chime in..
Thanks!

What's your build?

Good Afternoon Austin!

Say thanks for getting back to me!

What I have going is a 1971 Ford Bronco that has a 69 351W.  In the next couple of months I will be having my Fitech installed (600 HP).  After some research I have found that some of my Bronco brothers have opted to replace the Fitech pump with the Bosh pump (69100) as the Fitech pump is rather loud.  Please note after I had sent my 5/19 email I have found that some of the Bronco guys have used the following as a solution:

One Bronco guy said: I used this and installed on the high pressure side and on the other side that draws from the tank just used hose and clamp.

I will not be doing the installation and am really a fish out of water with the whole Fitech thing.  Just want to be sure I am doing what I can to help my mechanic.  Your input is greatly appreciated!  Rene

 

 

Most of us would recommend at the very least a 3/8 fuel line and 3/8 return.  I personally prefer an in tank pump with an LS return style filter regulator.  This reduces the work for vehicles without return lines already.

In your case, I am unclear if a 5/16 line will work.  If your motor is anything but stock, I would recommend going with 3/8.  I believe, in your case, it is the pump with the small fittings.  This can and will cause a restriction.

The easiest way to know if you have a fuel supply problem is to monitor your fuel pressure.  If your pressure drops at full throttle and/or high rpm, you have a fuel problem.

Good Morning Austin,

Say thanks for the feedback.  I'm thinking that I will do the initial set up with the Fitech pump provide and workout all the gremlins and then have the Bosh pump installed down the road.  Per your many recommendations, I did purchase the Fitech fuel pressure gauge.  I will update you on my progress regarding my success with Bosh pump.  Talk to you later, Rene
