First I think your idea of making a SS tank would just be a waste of time and money. Something else is causing problems in you fuel system and you need to find what it is and fix it. Next the theory that these fuel pumps have a poor suction is BS... Just for shits and giggles I put the top of my pump 10'8" in the air with a 10' hose and pulled mineral spirits through it with no problem and had between 85 and 90 psi, the same as with a 3" pickup. Please skip the lectures on hydraulic head and how a pump shouldn't be made to suck so much, I grew up with a Chemical engineer and I know all about it. My pump is getting mounted on top of the tank against the fire wall. This gives enough room to keep the spare in its place and out of the way in the garage. I have a hard metal line which runs into the tank which will have a screen on the end. I agree that hot air blowing on the tank isn't the best thing, but I don't think the temp in the tank is gets as high as you think. However I do have a design complete for a heat exchanger / chiller for the return line which theoretically can the temp to -10c. The only thing stopping me from building it is time or the lack of. If anyone with is interested in building it, its very simple and will cost about $25 in materials but needs about 2hr of machine time.

I definitely plan to do something different with mine. After driving less than 80 miles highway today from a full tank of fuel, the pump was grumbling/buzzing/screaming. I'm sure this is due to excessive fuel temperature. I'm probably going to install a fuel cooler on the return line and then consider mounting the fuel pump lower and outside the tank. I think that part of the problem is that the pump is already mounted too high. (Not to mention that those crappy fuel pump boots are not acceptable.) So if you are mounting yours even higher (on the fire wall) then I would expect problems. My strategy is to make a new tank out of stainless steel, put a nipple going out the bottom back which would have a flexible fuel line attached. Then the fuel pump would be mounted inside the frame next to the accumulator. These frames are already made with holes in the right places for this to work. And I hear Volkswagen Beetles use a similar arrangement. Walt To unsubscribe from this group, send an email to: DMCForum-unsubscribe@xxxxxxxxxxxxxxx Your use of Yahoo!
