fuel pump block off/dummy pump

Does anybody make/sell a more economical fuel pump block off/dummy pump? I'm looking for the kind that replaces the center guts of a mechanical pump. $60 bucks seems steep, but what do I know.....

Its a sizeable chunk of aluminum you have to start with, then a waterjet, or CNC to make them accurately, then drilling, tapping, and cleaning.

$60 doesnt seem cheap if you have to pay someone to do all those things, and keep up the machines to do them.

Bob - I think he is looking for the dummy CENTER for a mechanical fuel pump, so the car still appears stock, not the little round CNC plug for the pump hole

Here is a thread from 2013 that may be worth looking at.
The photo I have attached was in one of the replies as a possible method to make a bypass yourself but I for one would have my reservations about it.

I suspect it would take most mechanically inclined individuals that have never attempted to do this, at least four hours to potentially replicate this effort successfully.
If one were to value their free time at $15.00 per hour then add in the the cost of materials and the risk of failure, it probably is not cost effective.

My time in my opinion is worth more than that so spending the $60.00 to purchase a part that will bolt in and work is a no brainer.

Check with Dave Motohead and Clarks.
The solid block, I found style is best. No chance of leaks and the install looks stock.
I made my own with round aluminum pucks from McMaster Carr. However the labor for each makes selling them made my way prohibitive. But it's fun to make ones own solutions!

I have the Clark’s block and it looks great. Had no issues so far with it.

I posted that pic way back when. If I recall it took a couple hours to do.
I have had no trouble with it and it was not hard to do. I don’t track my time in terms of money. It’s a hobby for me and I like to try new things. The op can easily get one from Clark’s just as well. I don’t live in Cuba but I wouldn’t mind visiting there!

I used an old pump as a plug. They are very soft and easy to saw down. Just need to plug the shaft hole with a cap or sealer.

I am also having an issue shelling out $60 for a bypass plate to mount on the fuel pump. My current thoughts is to model the shape of the old pump block (seen below in gray), 3d print a filled in version allow a notch for the 5/16 fuel line and 1/4" barb to 1/8" NPT Female connection it, then paint it gray. Also will need to use hose clamps, preferably the full metal ones without the screw.

The ABS filament (3d part material) has a melting point of around 230 degrees celsius (428 Fahrenheit) and a glass transition temperature of 105 celsius (221 Fahrenheit) so I believe the 3D printed portion would survive.

The 5/16" fuel line is rated from -40 to +212 Degrees Fahrenheit.


Thoughts?
