You haven't told us what is wrong with the original pump, other than it leaks oil. So that's what AX's answer addressed.

For the time and money it would take to fix the mechanical pump, you could cap off its mounting and throw it away, and put a regulator in the line out of the electric pump. Many of us have gone this way because it is a superior system. The old pumps weren't made to take the chemicals in modern gas, and even with a diaphragm made of modern materials, they won't last as long as an electric. I could never find a good gasket for the glass bowl that would last more than a month on fuel that contained MBTE.

 

oh thats a cool idea. well can you point me to a website with a regulators? and perhaps which electric pump do you also recommend because i think the one i have is 5 to 15 psi which is too high. (yeah i dont know what's wrong with the old pump) - so could i just use a piece of aluminum over where the old pump is and bolt it on?

 

It reaaaally sounds to me lke you need to take this thing to a qualified mechanic. Don't mean anything by it , but some of the questions you are now asking leads me to believe that a mechanic needs to enter the picutre here.The fuel pump components are available at most auto parts stores. Plus if you are on the run, and live in this truck,the money you save buying it online would be spent in time trying to stay at a delivery address long enough to receive it. Most auto shops can have you fixed up in about an hour.

 

Well I just did a big post on how to test a mech FP, but then it ate it when I tried to post (I HATE that!).
Rather than redoing it, I really wouldn't bother replacing or repairing the mech fuel pump if you already have an elect. FP all hooked up and running. 5-15# is too much pressure for most carb needles and seats, 7# blows the needle off the seat on my brother's racing carb. Just get a regulator and block off plate from a parts store (NAPA etc.) or speed shop (local, Summit, Jegs, etc.).
Or whittle your own block off plate out of 1/4-3/8" aluminum plate using a fuel pump to block gasket as a pattern. Install the block off plate using the gasket and sealant, plumb the regulator into the fuel line between the pump and carb. Make sure you also have a fuel filter before the regulator. I prefer the inliner filters with the clear housing and pleated filter element, to be able to visually check the fuel flow and filter condition.

 

Yeah but most auto shops are way over priced and they're not cool people, including my own brother, he is a mechanic in indiana, and he is a dick! I can handle removing the pump and putting a cover on it. I think that's the plan. I haven't found any regulators yet. There is one on jcwhitney but its about 100 bucks, should I pay that much?

 

And I'm not on the run. California is home-base now. Southern California.

 

Take it to a mechanic, tell him to get a regulator for 3 psi and install it. It is likely that the 215 uses the same fuel pump block off plate as other common engines, or that one can be adapted. It should cost you less than getting towed one time when you get stranded.

 

my dad and i are going to do it. we just need to know where to get the regulator?

 

Summit sells a number of pressure regulators. Summit Racing - High Performance Car and Truck Parts | 800-230-3030
