Very good write up Matt ! Nice job.Very impressive.
Awesome write up! Thanks for documenting.
Nice job. Can't wait for the rest.
Thanks for the write up. Looking forward to hearing how you like it
Bill provides an inline fuel pump that you find on a Ford F-250 pickup truck I believe. As per the installation manual, you want to have the pump below the bottom of the fuel tank. The passenger side frame rail provides a perfect location. It allows nice easy access as you can see it through the rear wheel well. An inline filter which goes before the pump is also provided. To secure it, I decided to drill and tap 1/4-20 holes in the top of the frame rail. The straps provided by Bill with the fuel pump have a hole which is probably a 6MM. That's just a little too tight for a 1/4" bolt. I opened up the hole in the strap a little bit with a bastard file. My original install used regular hex head bolts. Given the way the strap was positioned, it made installation, tightening and everything else rather difficult.
You can also see in the above pic I used nylon spacers to stand off straps from the frame rail. Please ignore my lousy grounding wiring job. This gets corrected soon!
I ditched the hex head bolts and went to socket head bolts. Much easier to install. You can see how the strap and fuel pump tilt towards the bolt so getting a ratchet on a bolt head is almost impossible. Using an allen key is no problem! I also installed a proper ground to the frame rail. Here's a tip! The frame has 17/64" holes all over. That is the perfect hole size for a 5/16-18 tap thread! I used one of these holes for the fuel pump ground. Clean the surface real good!!!!
Looks good right? Well almost. As many of us know, electric fuel pumps have a very noticeable whine to them. MrsKenmore was not digging it and neither was I. I figured it just needed more isolation from the frame. I ordered from eBay 1/4-20 rubber isolators! 1" diameter and 3/4" tall.
And now with the fuel pump.......
The isolators totally worked and nearly eliminated the whine. Now I only hear the rubble of the mighty 196!!!!!
Very nicely done... I’m wrapping up an install of an AFI TBI for my 345 S2. I’ll be refereinging this post as I finish up in the next two weeks.
