Hello Don,
Please tell me that you are not drawing fuel out of that sump on the bottom of the fuel tank. Fuel pick-up tubes never reach the bottom of the tank for a purpose. That is where all the crap and WATER accumulate. The filter will keep the crap out of your engine but will let water pass right on through to the cylinders. If you ever suck enough water into a cylinder it will “hydro” and bring everything to a dead stop because water will not compress. You would have to pull that cylinders spark plug in order to rotate the engine and expell the water. Also, water would not be a good thing to introduce into your fuel system anyhow if it can be avoided. If I am wrong and it is a return line??, most top mounted pick-up/sending units would have a return line built in them for that size engine. Unfortunately, H2O is common in fuel tanks. You can get it from crappy gas and sweating that occurs in the tank during temperature changes.
Also, where you have penetrated the chassis with the fuel line make sure you at least grommet the holes, or best, clamp the fuel line on either side of the penetration to ensure that the line can never come in contact with the “knife-edge” created by the frame hole. Continued…….

I am looking at the location of your fuel filter and it appears to be right in the location of the lower control arm mount. Did you scarf those mounts off and do something different?
Also, you might want to provide some protection for that filter as that is where the rears like to sling rocks and such. Generally, running lines and locating filters inside the frame rails is safest albeit not the most convenient for filters.

I am still here Don. Your web sight has must have “anti-ramble” software in it, as it keeps cutting me off.
The reason I mentioned the securing if your fuel line through the frame hole is from experience with a power steering line. Just a slight contact with the frame did an incredible amount of damage in a short time. I ended up repaling the line and wrapping neoprene around it. Always open for questions…You’re getting there!!!
Talk to you later..Joe

Hi Joe …
If I didn’t tell you that I was drawing fuel from the sump on the bottom, I wouldn’t be telling the truth … it’s a gravity feed out the bottom to the pump. I plan to use a water absorbing additive that I used on my boat (that had aluminum gas tanks) and worked really well – never had a water-related problem in 11 years. The return line comes in on the top (opposite side).
The fuel line penetration will be grommeted as well (as soon as I can get a bigger drill bit). The stainless braided line is pretty tough but I know of what you speak. THe hole was deburred, chamfered, and smoothed but I think a grommet is still a good idea too. I have the correct size grommet – just need a bigger hole. I appreciate your thoughts on some real concerns. If it doesn’t work – we have the technology to fix it – but I’d rather not.

The filter is mounted inside the frame rail; it’s the pump that’s on the outside. The fuel line was run on the inside also – it crosses over the transmission and under the firewall to reach the driver’s side of the engine where the FI fuel rail pick up is located. I secured the line with cushioned clamps to keep it from vibrating in contact with the frame as well.
No scarfing control arm mounts here; they’re stock. What is different is the lower control arms by Global West (GW). The uppers are brand new Ford OEM.
The rear was from an ’89 Mustang that used to be a qaud shock unit. The outter shocks (anti-wheel hop stabilizers) were removed; hence the GW units for lower control arms.

Sorry about being cut off; I don’t know of any “anti-ramble” gremlins on the site. I’ll ask my son-in-law webmaster about it. Again, I do appreciate and welcome any and all advice and comment.
Oh yeah, the fuel pump itself is wrapped with a fairly dense foam covering for proection. I don’t think it’s real clear in the picture.
